DIGITALISATION –<br />
When the World<br />
Requires Realism<br />
YOU FIND AN INTERESTING WE-<br />
BINAR, article, or ad under the<br />
headline “Digitisation”. You<br />
participate in the event and<br />
get to know the subject enthusiastically.<br />
You paint in your<br />
mind incredible ideas on how to<br />
grow your business. In the end,<br />
however, you press your gaze<br />
to the ground and sigh deeply,<br />
because truly genuine solutions<br />
did not exist. There is still no<br />
moon in the sky -moment, but<br />
instead “let’s go brainstorming<br />
together”.<br />
There has been talk of digitisation ongoing for at least the last ten years, and<br />
various service solutions or products have been developed. In terms of maintenance,<br />
there have been discussions on analytics and simulation, artificial intelligence,<br />
machine learning, mobile solutions, and virtual and augmented reality.<br />
As a result, fault prediction, “pre-chewed” data with decision proposals (read<br />
artificial intelligence) and ready-made maintenance instructions for smart<br />
glasses have been promised. For the most part, digitalisation has been described<br />
as a “Superman,” but so far it has shown up more in its day job.<br />
In spring 2020, Covid-19 came and changed everything. Partly for an indefinite<br />
period of time, partly permanently. Earlier digitalisation was partly a<br />
choice, now it is forced. We are forced to find solutions and products that enable<br />
us to operate in changed circumstances. Solutions that can be implemented<br />
now, not in a five years’ time. Suddenly, digitalisation doesn’t have to be an allencompassing<br />
miracle from the planet Krypton. An honest and reliable engineer<br />
is enough. And here, I think, lies the whole thing.<br />
Ongoing digitisation discussion could be described as a 100-meter run. In<br />
the debate there has been a desire to run 100 meters in less than 10 seconds.<br />
This is possible, but the starting level has been at 13 seconds. Thus, we have to<br />
pull on our training clothes and humble ourselves to work towards the 10 second<br />
goal. It is good to know in which direction you are going, and there must be<br />
ambition. Personally, however, I also want to get a real picture and understanding<br />
of the present without the need to take off the mask.<br />
For example, would real-time and visualised data, online training spiced up<br />
with virtual reality exercises, and good mobile solutions be the realism that already<br />
provides significant benefits?<br />

MAINTWORLD INTERVIEW<br />
Adash portable vibration<br />
analysis devices nowadays.<br />
30 Years of Adash<br />
The Adash Company, a producer of vibration analysis instruments and software<br />
is celebrating its 30-year anniversary this year. Though this is an uncommon<br />
article here in <strong>Maintworld</strong>, we have decided to online interview Mr. Adam Bojko<br />
and Mr. Radomir Sglunda who are founders and owners of the Adash Company.<br />
We would like to know more about their successful worldwide business and<br />
basically why and how they started. How is the current market situation and<br />
how do they see a future of machine condition monitoring?<br />
MAINTWORLD: My first question is<br />
probably no surprise. What brought<br />
you two together and what lead you to<br />
a decision to start your own company<br />
concentrating on industrial maintenance<br />
and predictive maintenance in<br />
particular?<br />
RADOMIR: We met at the Coal Research<br />
Institute here in Ostrava in the<br />
6 maintworld 2/<strong>2021</strong><br />
mid 80s. Adash is based here in Ostrava<br />
too by the way. We were in the<br />
seismic measurements department.<br />
That was our first touch with a vibration<br />
analyser. Nobody knew in the beginning<br />
how to operate the B&K 2034<br />
vibration analyser, which was bought<br />
by the Research Institute for our<br />
measuring purposes. It was no surprise<br />
that all manuals where in Eng-<br />
lish only and we needed to study a lot<br />
all the new terms for us. We found out<br />
how to set up correct time waveform,<br />
FFT and other types of measurement<br />
for our seismic measurement purposes.<br />
But why did the manual keep<br />
talking about some "rotating machinery<br />
analysis"? This area was totally<br />
unknown to us, and we were curious<br />
to know more about it. We managed
MAINTWORLD INTERVIEW<br />
to get more materials about this<br />
method of predictive maintenance<br />
and started to offer our services to<br />
surrounding factories.<br />
MAINTWORLD: I presume that you<br />
were using competitors’ devices<br />
for your jobs in the beginning. But<br />
what was actually your first product<br />
under the Adash name?<br />
ADAM: We were young with not too<br />
much in the way of resources. We<br />
literally had just our PC. Therefore,<br />
there was only one way for<br />
us to start; to do some programming.<br />
Our first Adash product was<br />
software for Modal Analysis. Later<br />
on we got in touch with TEC from<br />
Knoxville and we made Operating<br />
Deflection Shapes at their instigation.<br />
However, this was specialized<br />
software for a limited amount of<br />
vibration experts. And we were<br />
hungry to catch a bigger audience.<br />
MAINTWORLD: Where did you see<br />
these bigger opportunities?<br />
The first Adash vibration analyser<br />
A4001 from 1995<br />
The first generation (1998) of the Adash<br />
bestseller. The legendary A4900 Vibrio M<br />
vibration data collector. Thousands of pieces<br />
and counting have been sold worldwide.<br />
ADAM: We wanted to attract the<br />
general public. Basically, guys in<br />
the field. People involved in dayto-day<br />
data collection. Adash was<br />
actually the first in the world to<br />
write route measurement management<br />
software DDS which was<br />
running under Windows 3.1 OS. We<br />
were selling it along with competitor’s<br />
data collectors and things finally<br />
started to move. We even sold<br />
tens of copies to our German rival<br />
Pruftechnik in the past when they<br />
did not have their own Windowsbased<br />
software yet.<br />
MAINTWORLD: So why did you also<br />
start hardware production if you<br />
were successfully selling your software<br />
with competitors’ hardware?<br />
RADOMIR: That is a simple answer.<br />
Competitors closed their hardware<br />
communication protocols. Therefore,<br />
our DDS software could not<br />
"talk" with their data collectors<br />
anymore.<br />
MAINTWORLD: Understood. I guess<br />
you started with a simple vibration<br />
meter, correct?<br />
ADAM: Actually no. Our first device<br />
in 1995 was a vibration analyser,<br />
data collector. We hired our<br />
first employee whose hobby was<br />
electronics, and he became our<br />
hardware development engineer.<br />
The vibration analyser A4001 was<br />
presented at the biggest Czech<br />
engineering fair in Brno that year.<br />
I remember the first version at the<br />
fair was not 100% ready for market.<br />
The batteries there drained in<br />
about 10 minutes, so we needed to<br />
be very quick while presenting to<br />
potential clients ☺. This battery<br />

MAINTWORLD INTERVIEW<br />
Adash online vibration monitoring<br />
systems nowadays.<br />
The first software in the world for route measurement<br />
management DDS running under Windows OS from 1993.<br />
The first Adash<br />
online vibration<br />
monitoring<br />
system A3600<br />
from 1996<br />
issue was of course fixed right after<br />
the show.<br />
MAINTWORLD: It seems there has been<br />
huge progress during the years as you<br />
have a wide range of portable and online<br />
monitoring equipment in your<br />
portfolio nowadays. How do you fight<br />
against competition and what is the<br />
current situation in your business area?<br />
RADOMIR: First of all we managed to<br />
find distributors in over 90 countries<br />
during the years. Competition will<br />
always be here which keeps us in pace<br />
to bring new things to clients. We are<br />
developing our products according to<br />
the end users’ requirements actually.<br />
We are listening to their suggestions<br />
8 maintworld 2/<strong>2021</strong><br />
of what should be improved or what<br />
features should be added to our software<br />
or hardware. Technical support<br />
from our distributors and from us is<br />
quite quick I think. We have unique<br />
measurement features and also, we are<br />
competitive price wise. Last but not<br />
least we offer 5 years warranty on our<br />
products.<br />
Our big competitors have been acquired<br />
by huge corporations during<br />
last few years. We think it will slow<br />
down their development in the future<br />
as they have lost independence.<br />
MAINTWORLD: Talking about the future.<br />
How do you see vibration condition<br />
monitoring in the future? What<br />
can we look forward to in Adash?<br />
ADAM: Despite concentrating now on<br />
our portable devices, I think factories<br />
will be turning more to 24/7 online<br />
monitoring systems. But we believe<br />
there will be still a group of vibration<br />
enthusiasts who will appreciate<br />
our portable systems. We also hear a<br />
lot these days about Cloud software,<br />
Wireless solution... We are currently<br />
working on Cloud-based software as it<br />
is a demand from clients to take a look<br />
at data from any part of the world and<br />
to look at the data via a mobile app. We<br />
are ready for Wireless data transmission<br />
to our devices. However, we have<br />
not found a reliable wireless accelerometer<br />
producer on the market so far.<br />

VANCAUWENBERGHE,<br />
Director of BEMAS,<br />
Wim Vancauwenberge (BEMAS)<br />
about Asset Performance 4.0<br />
Conference & Exhibition<br />
"Opportunity to give assets vitamin D in a targeted way”<br />
On 26, 27 and 28 October <strong>2021</strong>, BEMAS (the Belgian Maintenance Association)<br />
will organise Asset Performance 4.0, a hybrid conference and exhibition in Antwerp.<br />
The focus lies on the digitalization of maintenance; reliability and all other<br />
disciplines that influence the performance of assets.<br />
10 maintworld 2/<strong>2021</strong>
ASSET MANAGEMENT & TECHNOLOGY<br />
WIM VANCAUWENBERGHE, DIRECTOR OF BE-<br />
MAS, explains the context of the initiative:<br />
"Our world is in the middle of an extremely<br />
exciting phase of continuous digitalization.<br />
Sensors are becoming cheaper, machines and<br />
installations are getting a digital upgrade, data<br />
is being unlocked via the Internet of Things.<br />
The good old creed 'to measure is to know' is<br />
becoming more important than ever! Thanks<br />
to digitalization, this 'measuring' is done on<br />
an increasingly large scale, more accurately,<br />
more thoroughly ánd at a lower cost.<br />
The next step after measuring, the “knowing”,<br />
has also evolved greatly in recent years.<br />
Machine Learning and Artificial Intelligence<br />
allow sensor measurements and other data<br />
sources to be handled very differently. Thanks<br />
to smart algorithms, all data can be combined<br />
to detect deviations at an earlier stage, to predict<br />
what might go wrong and even to propose<br />
the necessary measures to predict problems.<br />
This may concern quality issues, abnormal<br />
energy consumption, and of course technical<br />
malfunctions. Digitization thus helps to take<br />
reliability and maintenance to a higher level.<br />
Vitamin D for Data<br />
Capturing and processing data is one thing.<br />
But the big challenge for an organisation is<br />
what you DO with it. The AP 4.0 conference<br />
will therefore also bring new insights and inspiring<br />
examples of how concrete benefits can<br />
be gained from the advanced digitization of the<br />
production process and asset management.<br />
"We see that organisations often already dispose<br />
of a lot of data. It is therefore especially<br />
important to set up those data and data flows<br />
correctly and to link them to intelligent algorithms.<br />
This allows all business processes to<br />
be boosted with the vitamin D of Data. We see<br />
that more and more organisations are combining<br />
existing good practices with new data-driven<br />
insights in order to create additional added<br />
value with their assets."<br />
Hybrid Conference<br />
& Exhibition<br />
"Since its launch in September 2020, the Asset<br />
Performance 4.0 platform has become a<br />
digital source of inspiration where more than<br />
900 users can find information and inspiration<br />
on digitization in asset intensive organisations.<br />
At the end of October <strong>2021</strong>, we invite<br />
everyone with an interest in this topic to the<br />
FMCCA in Antwerp. Those who participate<br />
on site can network and have in-depth discussions<br />
with the guest speakers and colleagues.<br />
However, it is also possible to follow the presentations<br />
online. Both asset owners and experts<br />
bring inspiring insights and share their<br />
experience with the new technologies. We<br />
also organise a hackathon, where companies<br />
can present their solution to the case live on<br />
stage. At the exhibition (also open for visitors<br />
who aren’t attending the conference), specialised<br />
companies present their best practices<br />
and digital solutions in maintenance, reliability<br />
and asset management. During the Asset<br />
Performance Awards, companies can win a<br />
prize with a case about a (digital) improvement<br />
project. Of course everything will be<br />
organised in accordance with the COVID-19<br />
measures in force at the time.<br />
"We are strongly committed to interaction<br />
and the exchange of experience. AP 4.0<br />
will be an inevitable appointment for anyone<br />
who wants to gain new insights into the current<br />
digitis not only limited to the conference<br />
on 26, 27 and 28 October, but will also<br />
continue to offer weekly webinars via the AP<br />
platform. All presentations made during the<br />
conference will remain available digitally.<br />
Participating therefore means keeping up to<br />
date.", concludes Wim Vancauwenberge.<br />

FOR THOSE COMPANIES considering a<br />
change, or assessing new solutions, it<br />
might be helpful to understand their<br />
many possible options. Some only add<br />
needless complexity and more work<br />

It is an ISA-95-compliant solution<br />

AssetWorX consists of a tree-like<br />
structure in which users can build<br />
a digital twin of their enterprise by<br />
mapping physical locations and business<br />
units, as well as equipment and<br />
machinery, all in one centralized<br />
system. This asset structure then<br />
provides a functional hierarchy for<br />
navigation and for data roll-ups.<br />
Lower-level equipment combines to<br />
form higher levels in the structure.<br />
Physical locations and areas of responsibility<br />
can be identified in the<br />
hierarchy.<br />
The asset tree provides a way<br />
to organize data sources (e.g., OPC,<br />
BACnet, database, web services, etc.)<br />
and visualizations (e.g., HMIs, charts,<br />
heatmaps, reports, etc.) in a logical<br />
hierarchical structure. For example,<br />
rather than OPC data sources being<br />
organized based on the address space<br />
of the server itself, these data sources<br />
can be organized based on the geographic/physical<br />
locations of the associated<br />
sensors (for example, by site,<br />
building, floor, machine, etc.), providing<br />
an invaluable level of contextualization<br />
for insightful analysis.<br />

Instead of configuring a separate<br />
system for each application (e.g., data<br />
management, aliasing, alarming, etc.),<br />
data from multiple applications can<br />
be configured into a single tree and<br />
organized in a logical structure that<br />
users define. Behind the scenes,<br />
AssetWorX uses existing configuration<br />
providers and services (as plugins)<br />
to configure existing applications.<br />
AssetWorX comes with multiple<br />
predefined nodes at the highest level<br />
of the structure. These nodes are:<br />
• ASSETS - where users can configure<br />
equipment and house their hierarchical<br />
asset tree.<br />
• EQUIPMENT CLASSES - templates<br />
that can be created for building the<br />
asset tree.<br />
• TREE VIEWS - allow users to better<br />
filter and reorganize items within<br />
tree-based navigation.<br />
• PRODUCT CONFIGURATION - where<br />
users identify preferences for<br />
AssetWorX settings.<br />
Within any enterprise, equipment<br />
can be interconnected according<br />
to its physical location or by the<br />
business units into which they are<br />
organized hierarchically. Users can<br />
easily define any number of those interconnected<br />
relationships using the<br />
asset tree. Each piece of equipment<br />
gets its own node in the asset tree,<br />
along with its own associated properties.<br />
A property might be a variable<br />
data source, a reference to an HMI<br />
graphic, an alarm, or a static value.<br />
It is within these equipment properties<br />
where the connection to additional<br />
possible analytics can be made<br />
to one of ICONICS popular analytical<br />
tools. One such tool, FDDWorX, is<br />
ideally suited for asset management<br />
and maintenance.<br />
Fault Detection and Diagnostics<br />
for a Proactive Maintenance<br />
Strategy<br />
FDDWorX is a predictive building<br />
automation solution that uses<br />
ICONICS’ advanced Fault Detection<br />
and Diagnostics technology. Configured<br />
within AssetWorX via Equipment<br />
or Equipment Class properties,<br />
it incorporates algorithms that<br />
weigh the probability of faults and<br />
advise maintenance personnel, operators,<br />
and management of actions<br />
to prevent equipment failures or<br />
excessive use of energy. When equipment<br />
failures occur, advanced software<br />
technology provides automatic<br />
guidance to a list of causes sorted<br />
by probability, resulting in reduced<br />
downtime and lower costs to diagnose<br />
and repair.<br />
FDDWorX collects equipment<br />
process data using industry-standard<br />
data collection mechanisms.<br />
It can automatically generate fault<br />
notifications and reports. Operators<br />
can use real-time displays to analyze<br />
relevant data such as the status of<br />
equipment operating outside the<br />
parameters of a given fault rule.<br />
The technology also takes into account<br />

Ultrasound and Vibration<br />
analysis: two key elements<br />
of predictive maintenance<br />
Vibration analysis has been for many<br />
years the technology of choice for<br />
maintenance professionals to monitor<br />
the condition of rotating assets.<br />
However, in the last years ultrasound<br />
has also emerged as a very popular<br />
technology for condition monitoring.<br />
The question that many are now asking<br />
themselves is: which one is best?<br />
Ultrasound or vibration? In this article<br />
we will focus on the role of ultrasound<br />
as a condition monitoring tool, and why<br />
using vibration and ultrasound together<br />
is the best way to reach excellence in<br />
your maintenance practices.<br />
Why vibration analysis?<br />
Vibration analysis is an incredible tool: it detects and measures<br />
small vibrations and what is causing them, thus allowing<br />
maintenance professionals to detect early failures on rotating<br />
equipment. Furthermore, vibration analysis gives us a very<br />
deep diagnostic and allows us to identify the failure’s root<br />
cause, and thus correct it to avoid further issues in the future.<br />
Plus, there are a great number of vibration sensors and solutions<br />
on the market to choose for, so maintenance teams can<br />
find a solution that is suitable for their needs.<br />
Why Ultrasound?<br />
Ultrasound is considered by many the first line of defence<br />
when it comes to bearing failures, since it can give a very early<br />
warning of a potential problem, even with lubrication issues.<br />
The way ultrasound does that is by monitoring the friction levels<br />
on rotating equipment. The concept is simple: as a bearing<br />
starts to fail, or if it has not been lubricated properly (under or<br />
over lubricated), the friction levels rise. Friction creates ultrasound<br />
emissions that can be picked up by an ultrasonic handheld<br />
device or sensor and translated to low frequency sounds<br />
that the inspector can hear. Ultrasound equipment will also<br />
provide a decibel level – and the higher the decibel, the higher<br />
the friction.<br />
Ultrasound or vibration?<br />
There is no easy answer to this question, but one thing is for<br />
sure: if a maintenance team wants to reach excellence, both<br />
technologies should be used. Ultrasound will provide the<br />
earliest warning of failure and is also very easy to use, since it<br />
relies on simply trending decibel levels. Vibration analysis is<br />
extremely complete and will give maintenance professionals<br />
a deep overview of the issue and the root cause of such issue.<br />
Almost as if ultrasound is the doctor who detects the problem,<br />
and vibration is the health specialist that will diagnose it properly.<br />
We will now talk about a few situations where, in general,<br />
ultrasound can be used instead of vibration analysis.<br />
18 maintworld 2/<strong>2021</strong>
ASSET MANAGEMENT<br />
Slow speed bearings<br />
Slow speed bearings are difficult to monitor. Since they rotate<br />
very slowly, it is difficult for vibration sensors to pick up<br />
significant changes in vibration. Even with an ultrasound instrument<br />
it may be difficult to pick up failures if we rely only<br />
on decibel levels, since in extreme slow speed bearing applications<br />
(usually less than 25rpm), the bearing will produce little<br />
to no ultrasonic noise. However, high-end ultrasonic devices<br />
will allow for sound recording: by recording the sound of the<br />
bearing and checking it in a spectrum analysis software, we<br />
can easily find peaks in the sound spectrum amplitude which<br />
indicate a fault in the bearing.<br />
First line of defence, easy to use<br />
For a maintenance professional to properly work with vibration<br />
analysis, significant training and experience are needed.<br />
On the other side, ultrasound has a much quicker learning<br />
curve. And this is because of how the technology works: since it<br />
is monitoring friction levels and translating them to dB values,<br />
we can easily check for potential problems with our rotating<br />
equipment. Once we setup a dB baseline for a bearing, we just<br />
need to trend the dB value overtime. So, if the baseline for a<br />
bearing is 20dB, but the ultrasonic instrument reads 32db, we<br />
already know there is a problem simply by comparing values.<br />
Lubrication<br />
Again, because ultrasound is based on the friction levels, it<br />
is perfectly adequate for bearing lubrication. Is the bearing<br />
lacking lubrication? Then the friction levels will increase,<br />
and we can hear that through the ultrasonic instrument and<br />
see it in the dB levels. If we start lubricating the bearing,<br />
most likely we will see a decrease in the sound intensity and<br />
the dB levels. Did the bearing receive too much lubricant?<br />
Then again, friction levels will increase, and we will know<br />
that using the ultrasonic instrument. Thus, ultrasound is<br />
perfect to avoid under- and over-lubrication issues.<br />
Versatility<br />
While vibration analysis is an extremely powerful tool, its<br />
uses are limited to mechanical equipment. On the other hand,<br />
ultrasound has a wide range of applications which makes it<br />
a very versatile technology. One of the most popular applications<br />
of ultrasound, besides condition monitoring, is energy<br />
savings. Since turbulence also creates ultrasound emissions,<br />
the ultrasonic instruments can easily be used for leak detection<br />
(compressed air and other gases), steam traps inspection and<br />
even for electrical inspections, to detect issues such as corona,<br />
tracking and arcing.<br />
Conclusion<br />
We believe, as many other maintenance professionals nowadays,<br />
that using multiple technologies that complement each<br />
other is the way to go. Therefore, the question is not ultrasound<br />
vs vibration, but instead ultrasound AND vibration and when<br />
we should be using one or the other. Both are very powerful<br />
condition monitoring technologies and, when used properly together,<br />
can really take any maintenance and reliability program<br />
to the excellence level.<br />

The heat is on<br />
All rotating machinery are subjected to thermal<br />
exposure. The machines will react depending on<br />
temperature and material. Either by expanding or<br />
shrinking. And that is a fact. Thermal growth is a<br />
serious thing when you think about it.<br />
The machines might expand differently<br />
ALL ROTATING MACHINERY are installed<br />
in trains. Trains means there is a driver,<br />
which is the motor, and driven which can<br />
be the pump, blower, compressor, or any<br />
different process machine. When rotating<br />
machinery is installed, precision shaft<br />
alignment is performed. Shaft alignment<br />
will ensure both shafts (driver and driven)<br />
are collinear. Collinear means that both<br />
rotational centrelines are positioned as if<br />
they were one.<br />
Different situations<br />
When the machines are started the driver<br />
and driven heat up in very different ways.<br />
A compressor in a hot environment will<br />
quickly increase in temperature due to<br />
friction of its internal rotating parts, and<br />
compression of the media will generate<br />
and add more heat. Comparing to the<br />
20 maintworld 2/<strong>2021</strong>
ASSET MANAGEMENT<br />
driver, which can be an electrical motor, the<br />
situation is very different. The temperature<br />
will increase to a certain level and then<br />
remain the same. Two machines with two<br />
different behaviours.<br />
So, what happens when one of them<br />
increase its temperature respectively to the<br />
other? It’s simple; the machine will start expanding.<br />
And when the machine expands,<br />
it will grow in all directions and move its rotational<br />
centre out of collinearity and cause<br />
misalignment. But not only misalignment.<br />
Since there is a change in the machine geometry,<br />
pipe strain might also appear adding<br />
more stress to the housing.<br />
Many consequences<br />
There are so many consequences of<br />
thermal growth in rotating equipment.<br />
Misalignment will for example also result<br />
in bent shaft. Bent shaft will result in unproper<br />
distribution of forces in the bearing<br />
which in turn will lead to failure of the<br />
lubrication. Therefore, we must be able to<br />
anticipate thermal growth by using available<br />
information from the OEM, or by<br />
performing the calculation by ourselves.<br />
How do we do that? The key is to identify<br />
how much growth is expected. This<br />
ALL ROTATING MACHINERY<br />
ARE SUBJECTED TO<br />
THERMAL EXPOSURE.<br />
THE MACHINES WILL<br />
REACT DEPENDING<br />
ON TEMPERATURE<br />
AND MATERIAL.<br />
Thermal expansion by material<br />
number must be used when performing the<br />
shaft alignment to “intentionally misalign”<br />
the machines prior to start. Let us use the<br />
compressor as an example again. If we assume<br />
that the compressor will operate at<br />
higher temperature than the motor, when<br />
aligning, we must place the compressor below<br />
the rotational centreline of the motor.<br />
How much will be determined by expected<br />
thermal expansion growth of the material.<br />
Test run<br />
When the machine is aligned considering<br />
the thermal growth, it must run and operate<br />
until it reaches its full operating condition.<br />
Then it must be stopped, and the shaft<br />
alignment must be verified. This is our test<br />
run of the machine to confirm proper and<br />
reliable installation to be able to achieve<br />
full operational life. We want to test before<br />
we go to full production to make sure our<br />
thermal expansion calculation was right.<br />
Think about aircraft maintenance. When<br />
there is an aircraft engine replacement, to<br />
make sure it is operating as it should, the<br />
pilots perform test flights until everything<br />
can be confirmed. And you don’t want to be<br />
on the plane knowing nobody performed<br />
the test run, do you?<br />

Processes:<br />
why should we?<br />
Admittedly, writing out uniform work<br />
processes with associated roles and<br />
responsibilities is not exactly a task to<br />
look forward to. It is like cleaning up<br />
the attic, which over the years has become<br />
cluttered with boxes. However, if<br />
you put some effort into this you will<br />
benefit from overview, structure, clarity,<br />
and a much more efficient way of<br />
working. Ready to roll up your sleeves?<br />

DOES YOUR ORGANIZATION HAVE WRIT-<br />
TEN MAINTENANCE PROCESSES? Is the<br />
content of the functions within maintenance<br />
exactly the same in every department?<br />
And are ‘best practices’ easily<br />
shared between branches and departments?<br />
– Chances are you have to admit that<br />
something could certainly be improved.<br />
We hear this a lot, says Peter Decaigny<br />
of Mainnovation.<br />
– But anyone who can answer the<br />
above questions with ‘yes’ has a good<br />
basis for streamlining the organization<br />
and/or successfully implementing an<br />
IT tool. And this is the foundation for<br />
further improvements in effectiveness<br />
and efficiency.<br />

Clutter in the Attic<br />
Many Maintenance and Asset Management<br />
organizations have grown organically<br />
and there is nothing wrong with<br />
that. It all makes sense to the people<br />
involved in this growth. Maybe some<br />
choices were a compromise under pressure<br />
from stakeholders at the time.<br />
Sometimes organizations are built<br />
around people and not based on clear<br />
roles and responsibilities. Some IT tools<br />
are configured to mimic the functionality<br />
of old IT tools. And often, in large<br />
companies, the different maintenance<br />
departments or teams work in completely<br />
different ways.<br />
It is like ‘clutter in the attic.’ In the<br />
beginning there was a system, a certain<br />
storage structure, but more stuff was<br />
added and eventually you find you first<br />
have to move other boxes, before you<br />
find the right box. "Efficiency can be<br />
gained. This starts with cleaning up<br />
and drawing up a plan on how to prevent<br />
this cluttering."<br />
Uniform work processes<br />
With a process map you can describe<br />
the future (desired) situation. This<br />
document is a detailed description of all<br />
processes that are important within the<br />
Maintenance and Asset Management<br />
organization.<br />
Uniform work processes can be written<br />
down in two ways: you either start<br />
from scratch with noting down all steps<br />
in a process, or you can use an existing<br />
process map. "Obviously, both ways have<br />
advantages and disadvantages," explains<br />
Decaigny. "With a blank start, everyone<br />
can have their say, which results in<br />
commitment. However, it is very timeconsuming."<br />
By using an existing process<br />
map, there is already a considerable basis<br />
and this is of course a time saver. "But in<br />
this case that basis must be good, obviously.<br />
After all… reorganizing the attic<br />
when the floor is rotten, wouldn't be a<br />
good idea."<br />
Based on best practices<br />
That is why Mainnovation uses the<br />
VDM XL Process Map. This Process Map<br />
is based on proven ‘best practices’ of leading<br />
Maintenance & Asset Management<br />
organizations from various industries.<br />
This method is written down in more than<br />
60 work processes that together form the<br />
VDM XL Process Map. This template is then
PARTNER ARTICLE<br />
critically assessed in various workshops<br />
within your company. What is missing<br />
and what is or is not applicable for this<br />
organization?<br />
– And yes, that works, says Decaigny.<br />
– Process operations are often very<br />
generic and by fine-tuning them we get<br />
a process map that is very customerspecific.<br />
– There are companies that claim<br />
that they have already written maintenance<br />
processes in place, says Decaigny.<br />
– But in most cases they are based<br />
on what the ISO 9.001 manual provides.<br />
However, these process descriptions<br />
are of little value for restructuring an<br />
organization. They are too high level<br />
and do not provide enough guidance for<br />
the next steps.<br />
The next step would be to use the<br />
processes – that describe what needs<br />
to be done – for assigning the roles and<br />
associated responsibilities and KPIs.<br />
And the ultimate result is the practical<br />
work instruction that emerges from<br />
this. This describes the necessary actions<br />
with a focus on how things should<br />
be done.<br />
Roll up your sleeves<br />
This probably sounds like a tremendous<br />
amount of work. Sitting at the<br />
computer for days and writing, evaluating<br />
and writing again. Arguing the<br />
right approach because nobody wants<br />
to change their way of working. You<br />
can of course save this task for a rainy<br />
day, but the clutter in the attic will<br />
pile up ...<br />
And there are several reasons to<br />
roll up your sleeves anyway.<br />
– A uniform process map is a perfect<br />
starting point for ISO certification.<br />
The VDM XL Process Map connects<br />
seamlessly with ISO 55000.<br />
When a multisite company decides<br />
to implement one EAM system for all<br />
locations – which occurs regularly –<br />
the process design can be used as a<br />
blueprint for this (future) common<br />
IT tool.<br />
– Of course, there can still be differences<br />
in how the organization is set up.<br />
When responsibilities are assigned to<br />
a particular role rather than a specific<br />
job, uniform procedures can still be<br />
used. After all, you want the implementation<br />
to take place in a way that<br />
is labelled as most effective and most<br />
efficient. It goes without saying that<br />
this way of working delivers value, Decaigny<br />
explains.<br />
A uniform working method also has<br />
advantages for training (new) employees.<br />
– In short, it pays off. It takes time<br />
and commitment but rolling up your<br />
sleeves now means creating room for<br />
improvement and growth in the future.<br />

SDT Proudly Announces Vigilant<br />
SDT Ultrasound Solutions is excited to announce<br />
the release of Vigilant, the newest<br />
addition to its family of permanent condition<br />
monitoring solutions. Vigilant is an 8-channel<br />
online condition monitoring solution that combines<br />
the versatility of ultrasound diagnostics<br />
with the analytics of vibration data. An<br />
additional 4 channels allow inputs for more<br />
conventional machinery information such as<br />
temperature, RPM, and other process data.<br />
VIGILANT is a stand-alone solution. With its own embedded<br />
software contained within the measurement pod, anyone with<br />
network credentials has access to critical asset health via a web<br />
browser. Using standard communications protocols like Ethernet,<br />
OPC, and Modbus TCP, Vigilant’s communication capabilities<br />
makes the sharing of asset data to other information systems easy.<br />
“ There are many applications where using a single condition<br />
monitoring technology to attempt to identify a failure mode doesn’t<br />
net the outcomes needed by reliability planners”, explains Vigilant<br />
product specialist Robert Dent. “ Vigilant combines insights from<br />
two proven technologies to bring conditional data into a common location,<br />
while providing industry standard tools to perform analysis.”<br />
As assets become more heavily guarded for safety protocol, condition<br />
monitoring teams need more creative ways to access collection<br />
points. Vigilant solves the accessibility dilemma by mounting<br />
low-cost, high-quality permanent ultrasound and vibration sensors<br />
to the asset, and then connecting the data directly to the asset owner.<br />
“ SDT Ultrasound Solutions has always provided ways to collect<br />
and combine Ultrasound and Vibration measurements with our<br />
handheld portable systems”, said SDT’s Benoît Degraeve, area sales<br />
manager and Vigilant product specialist in Europe. “ Today, we do the<br />
same thing with Vigilant, in a safe, reliable and permanent way.”<br />
Vigilant is available in two configurations: Mobility and Permanent.<br />
Vigilant Mobility comes packaged in a rugged, environmentally<br />
protected carrying case and is designed to travel with you to fieldlevel<br />
critical assets where temporary 24/7 monitoring is required.<br />
Vigilant Permanent installs and remains on an asset for its life cycle.<br />
Protected in your own enclosure, Permanent requires a 24V power<br />
source and communications connection.<br />
Vigilant manages both Static and Dynamic data, creating an opportunity<br />
to establish long-term trending, analysis, and diagnosis at<br />
the earliest point in the failure curve.<br />

Reliability and Maintenance<br />
Management (RMM)<br />
- The frontline of maintenance<br />
Many Reliability and Maintenance improvement initiatives fail to deliver<br />
sustainable (and continuously improving) results in improved safety,<br />
manufacturing throughput, and costs. There are many reasons for this, but the<br />
lack of engaged, visible, and caring plant leadership is the most common of them.<br />
CHRISTER IDHAMMAR, Founder IDCON INC.<br />
26 maintworld 2/<strong>2021</strong>
ASSET MANAGEMENT<br />
TAKING REGULAR WALKS to visit the frontline of maintenance,<br />
or Gemba walks, is an excellent way for a leader to demonstrate<br />
engagement. Such walks take management to the front lines<br />
showing that they are an engaged, visible and caring leader<br />
and also enables them to learn first-hand what improvement<br />
opportunities exist. You are visible and you show that you<br />
care. This is key to successfully improving your maintenance<br />
organizations’ performance and delivering continuously better<br />
results.<br />
Gemba, sometimes spelled Genba, is Japanese for “where<br />
things happen,” or "the real place." It can be anything from an<br />
actual crime scene to the context of an RMM organization,<br />
where planners, front-line leaders, coordinators, engineers,<br />
operators, crafts people cand storeroom employees close to the<br />
manufacturing floor make things happen. They are the ones<br />
who will execute your initiatives, such as preventive maintenance,<br />
work management, stores organization including,<br />
delivery and “kitting” of parts and material, and many more<br />
improvements. If they do not execute your initiatives, then all<br />
you have is a plan.<br />
As leaders, we are often pressed for time, but carving time<br />
to engage with the frontline is crucial for success. Remember -<br />
improving reliability and maintenance performance is “90%”<br />
about people and processes, so it is important that you are visible<br />
and available.<br />
If you organize and schedule frontline walks well, you will<br />
find that it does not have to take much time. You will also find<br />
it interesting and rewarding when you see the appreciation and<br />
improvements.<br />
I suggest the following steps for your frontline walks initiative:<br />
1. Organize and plan<br />
2. Inform<br />
3. Observe and learn<br />
4. Ask questions, meet face to face<br />
5. Act and follow up<br />
1.Organize<br />
Depending on the size of the Maintenance organization, the<br />
plant manager might do a frontline walk once a quarter per<br />
production area. Operations and Maintenance managers<br />
might do the walk together once a month in their respective<br />
areas. Supervisors should do it weekly.<br />
Set up an improvement activity to focus on for each walk.<br />
Do not include things already on your meeting agendas. No<br />
need for duplication.<br />
It is very beneficial if you have done an assessment of improvement<br />
opportunities and a plan on how to close the gap<br />
between how good you are now to how good you can become in<br />
three to five years.<br />
If you have done that and have identified the gaps you need<br />
to close, it will serve as a setup- and focus guide, for each walk.<br />
This will most likely include the following areas to improve<br />
upon.<br />
• Lubrication practices<br />
• Precision maintenance practices<br />
• Basic inspections and predictive technology<br />
• Work management<br />
• Storeroom management<br />

ASSET MANAGEMENT<br />
By taking full advantage of the<br />
purpose of a frontline walk, you<br />
will show that you are engaged,<br />
visible (accessible) and caring.<br />
There can be other areas, but as good maintenance always<br />
requires—the basics must be executed well before you will be<br />
in a position to move towards excellence. Most plants I work<br />
with need to focus on the areas mentioned above.<br />
In a small plant the walk could include several improvement<br />
areas, while it will be necessary to select one or two focus<br />
areas in a bigger plant. Try to limit the “Observe and learn”<br />
and the “Ask questions, meet face to face” to 30 minutes each.<br />
These steps can be done the same day or on different days.<br />
2.Inform<br />
When you organize and plan your frontline walks, it is very<br />
important to share why and how you will do them with those<br />
involved.<br />
If you, as a plant, maintenance or operations manager, have<br />
a habit to be visible on the manufacturing floor and often talk<br />
with the frontline people, the walks will help organize your<br />
visits towards defined and selected improvement areas. For<br />
frontline leaders this is, of course, not much of an issue as<br />
you work closely with your people daily. If you, as a manager<br />
have kept a distance to the frontline organization it may be a<br />
welcome change. If your visibility was limited in the past, your<br />
appearance may be associated with trouble. This will change<br />
when people understand why and what the Gemba walks<br />
mean to the whole organization.<br />
3.Observe and learn<br />
Before you do “Ask questions, meet face to face” walks—visit<br />
the chosen production area you will observe and study the<br />
IN A SMALL PLANT THE WALK COULD<br />
INCLUDE SEVERAL IMPROVEMENT<br />
AREAS, WHILE IT WILL BE NECESSARY<br />
TO SELECT ONE OR TWO FOCUS AREAS<br />
IN A BIGGER PLANT.<br />
equipment so you can ask the right questions. The first time you<br />
do this walk preparing questions might take a bit more time.<br />
If you chose lubrication practices in one area you should look at:<br />
• Blown out seals indicating too much grease and poor<br />
seals.<br />
• Use of tools to measure grease volume on grease guns.<br />
• Clean tools and grease points.<br />
• Oil levels in gears, pumps etc.<br />
• Keep oil level indicators clean to see levels and colour of<br />
oil.<br />
• Right oil levels marked.<br />
• Lubricant type marked with a symbol.<br />
• Lubrication stores clean and organized.<br />
• Air breathers/filters installed where needed. Change in<br />
colour?<br />
• Leaks.<br />
• Long grease lines for manual greasing.<br />
28 maintworld 2/<strong>2021</strong>
If you chose Precision maintenance practices in one area you<br />
should look at:<br />
• Jacking bolts installed for precision alignment.<br />
• Jacking bolts backed off and not pushing on alignment<br />
object.<br />
• More than three shims used for alignment.<br />
• Beat marks on equipment feet.<br />
• Vibrating fans and high-speed equipment.<br />
• Filters for mechanical seals and hydraulic fluids.<br />
Other operating practices you should look at include if<br />
your redundant pumps are running equal time per each<br />
schedule and who is responsible for shifting the pumps<br />
according to that schedule. For more tips on what to<br />
look for during your walks, take a look at IDCON’s new<br />
series of Gemba videos at our website or our YouTube<br />
Channel.<br />
4. Ask questions, meet face to face<br />
After “Observe and learn”, you have the material to be<br />
well prepared to meet face to face and ask questions.<br />
Meet with the people in production who are responsible<br />
for various areas like lubrication, for example. Ask<br />
open-ended questions such as: “I saw a lot of grease<br />
pushed out from the drive side bearing of the fan pump,<br />
what can we do about that?” The answer might be: “That<br />
seal was gone a long time ago, so we need to purge out<br />
the water to save the bearing, we have asked to have it<br />
replaced many times. We also have new lubricators who<br />
have not been trained and think the more grease the<br />
better. We have also asked to get grease meters to put<br />
on the grease guns, so we know how much grease each<br />
point gets.”<br />
Other possible questions: “What would you like to<br />
spend more or less time on?”<br />
For the lubrication program, “What is the most important<br />
thing to improve upon?”<br />
The discussion will teach you a lot. But perhaps more<br />
importantly is the motivation you create by being engaged,<br />
visible, and caring as a leader. This goal will only<br />
be reached if you continue these walks.<br />
5. Act and follow up<br />
Be prepared for suspicion. Many people have seen new<br />
improvement initiatives come and go and may not be impressed.<br />
You have to prove this will be a continuous practice.<br />
During the frontline walks it is important to take notes<br />
and pictures. This will take less and less time as it becomes<br />
routine. It is important to inform your people what you decided<br />
to act upon. If you decided to get the equipment lubricators<br />
needed and train all lubricators, for example, then you<br />
might want to change the damaged seals. It is equally important<br />
to share what you decided against, and why.<br />
When well-organized, the five steps of the frontline walks<br />
will take a manager in a big plant about an hour per quarter/<br />
area. For operations and maintenance managers walking<br />
together it might take an hour a month per area, and frontline<br />
leaders much less time per week. I am sure you will find<br />
it worth the time as your Safety, reliability and cost will<br />
improve.
ASSET MANAGEMENT<br />
From wrench<br />
to algorithm<br />
From “seeing” to “self-optimizing”: the past, present and future of maintenance<br />
What do monkey wrenches and computer algorithms have in common? Surprisingly,<br />
wrenches and computer algorithms are both invented in the same year 1840.<br />
DIRK DE NUTTE, CEO The Grain<br />
THE MONKEY WRENCH was invented<br />
by American knife manufacturer Loring<br />
Coes. On the other side of the ocean<br />
countess Ada Lovelace produced the<br />
very first "computer program" for the<br />
mechanical Analytical Engine (A.E.),<br />
invented by Charles Babbage named the<br />
father of computers, to calculate Bernoulli<br />
numbers.<br />
Ada Lovelace was not only a brilliant<br />
mathematician, she also discovered the<br />
full potential of this engine, developing<br />
the first algorithm[1]for the A.E. and<br />
becoming as such one of the first computer<br />
programmers. And now, some two<br />
centuries later, computers and wrenches<br />
seem to come together in a new era of<br />
maintenance.<br />
Nothing has changed<br />
but everything changes<br />
Maintenance and repair have been<br />
around as long as mankind exists. From<br />
the time-based sharpening of man’s<br />
earliest spears and tools to the maintenance<br />
concepts for modern equipment<br />
and technologies. Over these last couple<br />
of centuries maintenance has made an<br />
30 maintworld 2/<strong>2021</strong><br />
evolution and gradually merged from<br />
a corrective approach known as “break<br />
and fix”, over a preventive or time-based<br />
maintenance towards a predictive or<br />
condition-based maintenance. And<br />
now we are moving into the new era<br />
of an integrated and digitized phase of<br />
prescriptive maintenance, combining algorithms<br />
of computer science with common<br />
maintenance techniques. By using<br />
artificial intelligence (AI), we can now<br />
master all kinds of data like asset health<br />
data, process data, historical maintenance<br />
data and contextual-operational<br />
data from various sources. We get better<br />
and in-depth insights on asset behaviour,<br />
allowing us to act before failure modes<br />
are manifested. With the AI approach we<br />
can now forecast asset failures modes,<br />
and thus optimize not only the asset<br />
performance but the total plant performance<br />
and production cycle.<br />
Even though our machines, industry<br />
and technology changed over time, the<br />
true foundational elements of how assets<br />
fail remain unchanged, i.e. the failure<br />
patterns and the P-F curve. To see what<br />
our future brings, it’s wise to know our<br />
past, and that’s why we’ll make a brief<br />
journey through the history of modern<br />
maintenance.<br />
From the first industrial<br />
revolution until WOII<br />
During this period maintenance gradually<br />
changed from “break and fix” to<br />
“time-based maintenance”. This is the<br />
era of descriptive maintenance where<br />
engineers “see” and “feel” failures.<br />
Maintenance management has its origins<br />
in the manufacturing industry. The<br />
invention of the steam engine, together<br />
with other inventions like telephone and<br />
radio announced the start of the first<br />
industrial revolution in the 18th century.<br />
At the same time a gradual shift from<br />
human labour to machine production<br />
began. The maintenance strategy was<br />
very simple: keep the machine running<br />
until it fails, only fix when broken. This<br />
is also known as corrective maintenance.<br />
Machine breakdowns were tolerated and<br />
considered “normal”.<br />
During the second industrial revolution,<br />
mid-to-late 19th century, electricdriven<br />
machines were invented and
ASSET MANAGEMENT<br />
those required a more sophisticated<br />
maintenance approach. Plant engineers<br />
became more “proactive” to maintain<br />
their equipment. They put a time-based<br />
maintenance strategy in place, and<br />
machine parts where replaced at specific<br />
time intervals. Unfortunately, this<br />
maintenance strategy was, and still is,<br />
quite expensive, as machines need to be<br />
shutdown causing production losses, and<br />
wasteful as parts are being changed according<br />
to a strict schedule whether this<br />
is necessary or not.<br />
Machinery at that time was rugged<br />
and “slow running”, instrumentation<br />
and control systems were very basic.<br />
Economy and production requirements<br />
were not as demanding as they are today,<br />
and breakdowns were a less critical issue.<br />
A break and fix approach and/or<br />
time-based maintenance strategy were<br />
adequately enough. At that time machinery<br />
was “over-engineered” and build<br />
very sturdily and inherently reliable.<br />
Post war till late sixties<br />
During this period maintenance matured<br />
from “Planned preventative maintenance”<br />
to the first concepts of “Reliability<br />
Centred Maintenance”. This is<br />
the era of early diagnostic maintenance<br />
where maintenance engineers “investigate”<br />
and “understand” failures.<br />
From the 1950’s onwards, the post<br />
war economy picked-up quite rapidly.<br />
Industries needed to be rebuilt, especially<br />
those of Japan and Germany. International<br />
economy started flourishing,<br />
creating a more competitive marketplace.<br />
Machine downtime was no longer<br />
tolerated and labour cost became an important<br />
factor leading to mechanization<br />
and automation. Machinery became less<br />
sturdy, was built lighter and ran at higher<br />
speeds. Equipment was used more intensively<br />
causing more wear out, more<br />
vulnerable and so less reliable.<br />
Japanese engineers started following<br />
the manufacturer’s instructions. This<br />
was also the period that the first maintenance<br />
associations and societies were<br />
created, and first global networks established.<br />
That trend gave birth to what<br />
we know as “preventive maintenance”<br />
today. Gradually, those associations encouraged<br />
technicians and other specialists<br />
to develop time-based maintenance<br />
schedules: machine lubrication, machine<br />
inspections, reporting any observations<br />
to help prevent machine damages.<br />
Maintenance and inspection checklist<br />
where used but the disadvantages of this<br />
strategy soon became obvious. The fact<br />
that very often machines needed to be<br />
shut down to perform these inspections,<br />
caused production losses. Repetitive and<br />
often boring interventions lead to negative<br />
“human behaviour” such as “PM<br />
creep” (adding or increasing frequency<br />
of PM’s to the program for no failure<br />
mode related reason) and “pencil whipping”<br />
(signing off on work that has not<br />
been done) causing ineffectiveness and<br />
unnecessary costs.<br />
With the arrival of the Boeing 747<br />
in the late sixties, the aircraft industry<br />
needed to improve reliability and therefore<br />
defined a detailed maintenance<br />
strategy reducing the risk of equipment<br />
failures. Risk had become a new driver<br />
for maintenance. This challenged the<br />
current maintenance strategies and<br />
the long-established basic assumption<br />
that the older equipment gets, the more<br />
likely it is to fail. Reliability centred<br />
maintenance (RCM), a new maintenance<br />
strategy approach was developed<br />
by Nowlan and Heap. The term was first<br />
used in public by United Airlines. Shortly<br />
after, the concept was quickly adopted by<br />
other industries.<br />
With time, other industries began<br />
understanding the value of maintenance<br />
and realised that it had a strategic impact<br />
affecting the bottom line. Since then<br />
proactive elements were increasingly integrated<br />
in well-balanced maintenance<br />
strategies, giving rise to other methodologies<br />
such as risk-based inspections<br />
(RBI), overhaul, etc.<br />
While predictive maintenance, focussing<br />
on eliminating failure modes, had<br />
become common practice in the aviation<br />
industry, the more conservative industry<br />
was lagging behind and still relying on<br />
time-based maintenance.<br />
From late 60’s till late 80’s<br />
During this period the notion of “maintenance<br />
service” and “condition-based<br />
monitoring” emerged. This is the era that<br />
diagnostic maintenance made its first<br />
steps into the broader industry.<br />
Between the 1960’s and 80’s, maintenance<br />
was considered a side activity<br />
and seen as of minor importance, only<br />
necessary when a breakdown occurred.<br />
The maintenance department’s scope was<br />
restricted and mainly limited to electrical,<br />
2/<strong>2021</strong> maintworld 31
ASSET MANAGEMENT<br />
mechanical repairs or greasing work. The<br />
notions of prediction or prevention were<br />
not at all integrated, and maintenance often<br />
suffered from a bad image.<br />
The industrial world, as well as the implications<br />
of failures, were however very<br />
different from the ones we know today.<br />
At that time, industry was burgeoning,<br />
consequences on production lines weren’t<br />
the same at all. Production shutdowns disrupted<br />
the production but weren’t leading<br />
to huge losses like today. During this period<br />
companies became progressively aware<br />
of the impact and importance of safety.<br />
Due to industry gearing to mass production,<br />
machines had become fast running,<br />
more advanced, more complex and were<br />
driven to their limits, causing higher risk.<br />
Hence, maintenance gained importance.<br />
The first maintenance procedures<br />
were developed, reducing working accidents<br />
and avoiding critical breakdowns.<br />
Interesting to note is that the main driver<br />
was human integrity (safety) rather than<br />
economic reasons. That gave a boost to<br />
the maintenance evolution in this period.<br />
Maintenance norms and standardization<br />
were progressively implemented, and<br />
they became necessary to train and certify<br />
technicians. The first trainings and certifications<br />
were implemented in this period.<br />
Precision maintenance slowly became<br />
common practice, extending the lifecycle<br />
of assets by integrating proper procedures<br />
and standards during installation or repair<br />
of equipment.<br />
From the 80’s till early 2000<br />
During this period maintenance and reliability<br />
engineering methodologies start becoming<br />
common practice in industry. This<br />
is the era of predictive maintenancewhere<br />
maintenance engineers are “prepared for<br />
what will happen next”.<br />
Surging globalisation gave rise to<br />
a further evolution of equipment and<br />
technology. Between 1980 and 2000, the<br />
industrial world changed in many areas:<br />
IT, maintenance, purchasing, communications,<br />
production, quality, safety. In<br />
the maintenance world “optimization”<br />
became crucial to survive. New concepts<br />
such as total productive maintenance<br />
(TPM), total quality management (TQM)<br />
and “lean” originating from Japan were<br />
implemented. The industrial sector was<br />
forced to modernize and adapt to secure<br />
their place on the globalizing market. It<br />
is then that computer maintenance management<br />
systems (CMMS) and quality<br />
management standards such as ISO-9000<br />
(1987) and others were implemented.<br />
FURTHER INTEGRATION OF THE<br />
DIGITAL AND PHYSICAL WORLD<br />
ENABLES CLOSE INTERACTION<br />
BETWEEN MACHINES,<br />
ALGORITHMS AND HUMANS.<br />
Many industries focused on increasing<br />
production and lowering production<br />
costs. So, equipment reliability and availability<br />
became of the utmost importance.<br />
Early detection of failures, increasing<br />
meantime between failures (MBTF), reducing<br />
the meantime to repair (MTTR),<br />
performing pro-active maintenance activities<br />
became the focus of maintenance<br />
departments.<br />
Engineering departments started taking<br />
maintainability and reliability considerations<br />
into their design, extending<br />
the asset’s life cycle. The awareness grew<br />
that the maturity and quality of a maintenance<br />
program is determined by being<br />
ahead of the P-F curve.<br />
During this period industry and their<br />
maintenance departments were confronted<br />
with increasingly and numerous<br />
hurdles. Apart from the fact that economic<br />
drivers put margins under pressure<br />
and cost control was often affecting<br />
maintenance departments first, maintenance<br />
also struggled, and even so today,<br />
to attract young and skilled people. This<br />
is mainly due to a lack of good image and<br />
the true understanding of the job content<br />
and how rewarding it is.<br />
Although much has happened since<br />
the start of the industrial revolution the<br />
past 200 years, it appears that the most<br />
dramatic changes have occurred within<br />
the last 30 years. Especially from the<br />
year 2000 onwards (the IT bug-century<br />
flip) to date, innovations in technology<br />

ASSET MANAGEMENT<br />
in every area of life are more than they<br />
have ever been in human history and<br />
maintenance management is not left out.<br />
A growing awareness of the value of continuous<br />
improvement and optimised asset<br />
management became obvious. During<br />
this period, an accelerated shift and interest<br />
in developing failure mode driven<br />
equipment maintenance plans, boosted<br />
predictive maintenance.<br />
From early 2000 to 2025<br />
The period where maintenance is evolving<br />
from “analysis to analytics” – the<br />
quantum leap. A new era of prescriptive<br />
maintenance where asset managers, maintenance<br />
managers and operators jointly<br />
use artificial intelligence to predict asset<br />
behaviour and define “what’s the best that<br />
can happen”. We are gradually entering a<br />
period where algorithms predict and allow<br />
automated self-optimisationactions and<br />
humans get a new role defined!<br />
Leveraged by accelerated technology<br />
evolutions and driven by globalised market<br />
mechanics and a fast-changing world<br />
of “instant” and “green” expectations,<br />
the need for continuous perfection and<br />
optimisation have now become prime for<br />
various industries and are key to survive.<br />
More than ever this new truth and the<br />
need to transform from flexible production<br />
to agile production becomes clear,<br />
now that mass production is quickly moving<br />
towards mass customisation. Current<br />
strategies are being questioned and many<br />
amongst us find ourselves at the tipping<br />
point between exploitation and exploration<br />
of our businesses and individual roles,<br />
often leading to new business models.<br />
Even though one already understood<br />
that the true value of asset management<br />
lies beyond the physical asset itself, it now<br />
becomes possible to connect asset data<br />
with context-, process and organizational<br />
data in a better and more efficient manner.<br />
Or to phrase in our language: “Failures<br />
leading to losses due to technical problems,<br />
generally referred to as special cause<br />
losses, can now be blend with operational<br />
inefficiency parameters, referred to as<br />
common cause losses. Here lies the new<br />
window of opportunity to excel, improve<br />
and gain that last overall equipment effectiveness<br />
(OEE) or total plant performance<br />
improvement.<br />
With the emergence of Industrial IoT<br />
(IIoT) collecting data from equipment is<br />
moving from paper-based, excel sheets<br />
and manual inspections to fully automated<br />
systems, enhancing both data quality and<br />
quantity. IIoT enables remote asset monitoring,<br />
also exponentially increases the<br />
quantity and variety of parameters that<br />
can be monitored and this at a better cost.<br />
With artificial intelligence (AI), predictive<br />
analysis (deductive) will shift to prescriptive<br />
analytics (forecasting), allowing us<br />
to move from ‘what happened’ to ‘what’s<br />
the best that can happen’, improving total<br />
plant performance instead of only uptime.<br />
In this early 21st century period, driven<br />
by advanced analytics, we can notice two<br />
major strategic shifts in maintenance<br />
strategies.<br />
A first strategic shiftis one that moves<br />
our maintenance practice from a failure<br />
mode driven asset strategy to an OEE<br />
driven strategy. By combining equipment<br />
data with process data, quality data, performance<br />
data, contextual-operational<br />
data and other relevant information, artificial<br />
intelligence provides new insights<br />
in equipment and process behaviour. This<br />
will provide maintenance technicians,<br />
planners and operators with comprehensive<br />
new, accurate and real-time insights<br />
into asset performance, risks, (..) and allow<br />
them to maintain higher levels of asset<br />
availability.<br />
Root cause analysis (RCA), by applying<br />
fi. fault-tree analysis as well as causeand-effect<br />
or failure-modes-and-effects<br />
analysis (FMECA), is a fundamental part<br />
of any organization’s maintenance and<br />
reliability strategy. Today, however, these<br />
activities are often conducted manually,<br />
and their outcomes are rarely recorded<br />
in a centralized manner. Hence through<br />
digitization and advanced analytics these<br />
methodologies will be automated and updated<br />
continuously. Possible root cause(s)<br />
will be suggested by the system in which<br />
the maintenance expert and/or operator<br />
will acknowledge the ‘real’ root cause, so<br />
improving the accuracy of the analytical<br />
models. Similarly, this can also be applied<br />
for reliability centred maintenance<br />
(RCM), helping teams choose the right<br />
maintenance strategy for each (critical)<br />
equipment. This is a gamechanger in predictive<br />
maintenance.<br />
A second strategic shiftis moving from<br />
an OEE-driven to an Operational Excellence<br />
driven strategy. Combining OEE<br />
data with loading, planning and product<br />
supply chain data allows to improve total<br />
plant performance. Maintenance schedules<br />
will be aligned with production schedules<br />
to optimise total production, balancing<br />
demand and supply. Using AI within<br />
production enables now to shift from mass<br />
production to mass customization.<br />
Further integration of the digital and<br />
physical world enables close interaction<br />
between machines, algorithms and humans.<br />
New digital maintenance execution<br />
systems augmented (AR) and virtual reality<br />
(VR) will support technicians in real-<br />

time to perform standardized repairs in a<br />
safe way by using the right tools, procedures<br />
and instructions. Know-how will be captured<br />
digitally, visualised and made available<br />
for everybody. Operators will receive<br />
optimized setpoints for their production<br />
lines, can feed the systems with additional<br />
relevant information that will further improve<br />
the analytical model. Digitisation and<br />
humans go “hand in hand”.<br />
From 2025 and beyond:<br />
The future is a concept –<br />
it doesn’t exist.<br />
We now enter the unknown era of exponential<br />
change, new business models and<br />
renewed anthropocentrism. The self-optimising<br />
prophecy now becomes reality.<br />
In spite of what I stated above and<br />
recognising an accelerated evolution and<br />
change in our asset management landscape,<br />
realise this: “we ain’t seen nothing<br />
yet”. Until present evolution, even though<br />
continuously accelerating, still was very<br />
much a linear evolution. The way we think,<br />
work and act are still very much the same<br />
as they always have been. Admitted, we<br />
evolved and matured, got wiser and our<br />
working models went from a very “centralised”<br />
way of thinking, organising and behaving<br />
to a “de-centralised” format in the<br />
‘90s. But the reality today is that change,<br />
boosted by technology is shifting gear into<br />
an exponential acceleration. A mind trap is<br />
that often we overestimate the change that<br />
will occur in the next two years but underestimate<br />
the change that will occur in the<br />
next ten, affecting our strategic judgement.<br />
Think fi. about quantum computing, a<br />
technology rapidly maturing in the shadow<br />
of today already for some seemingly futuristic<br />
scenarios.<br />
As IIoT will make everything and everybody<br />
interconnected, and everything<br />
is continuously changing and interacting<br />
in these new agile environments, we need<br />
to accept and embrace new distributive<br />
models. Boundaries becoming vaguer, our<br />
world and our industries will continue<br />
to converge. We are undergoing an exponentially<br />
accelerated merge between the<br />
physical and the digital world. Therefor we<br />
need to escape from our traditional way of<br />
thinking, working and organising within<br />
our maintenance or production silo, and<br />
step into this volatile and complex new environment.<br />
We need to re-invent ourselves,<br />
our methods and our solutions and stop<br />
ignoring this change by progressing in a<br />
stubborn linear pattern: “We cannot solve<br />
our future problems with the same way of<br />
THE MOST IMPORTANT IMPACT<br />
OF TECHNOLOGY IS HOW IT<br />
CHANGES PEOPLE.<br />
thinking we used when creating them.”<br />
Based on real-time information we<br />
will be able to accurately predict and<br />
balance supply and demand improving<br />
our company’s bottom-line without<br />
compromising the quality of service and<br />
reach an almost optimum performance,<br />
by increasing productivity and profit to<br />
unseen limits. The newly required skills<br />
often go beyond our human capacity and<br />
that’s where technology gives us a helping<br />
hand. It is up to us, people, asset managers<br />
to question, master and control that<br />
change.<br />

provide full transparency in contracts between<br />
companies, suppliers and vendors.<br />
Digital fingerprints (encoded asset certificates)<br />
of each asset and process will be<br />
created, ensuring reliable and qualitative<br />
information. All information will be indisputably<br />
and incorruptibly recorded in<br />
appropriate registers, ensuring increased<br />
security of information. Smart automation<br />
will help us to transform processes<br />
that require interaction, data interpretation<br />
and decision making. Robotics will<br />
allow us to perform smart operations by<br />
automating processes.<br />
I could continue and elaborate on many<br />
other new technologies, but the moral of<br />
this story is: “nothing has changed, but<br />
everything changes”. Allow some slight<br />
exaggeration here, but we are not inventing<br />
anything new, though. We’re just using<br />
old, improved algorithm technologies from<br />
the 9th and 19th century. Just like we used<br />
thousands of years ago hieroglyphs to communicate<br />
between different tribes, today<br />
we call them “emojis”. Wrenches will probably<br />
still be used, but with an improved design<br />
or attached-integrated to a robot. And<br />
algorithms will not be calculated by human<br />
brains but will run on supercomputers.<br />
Conclusion: “Prediction is very difficult,<br />
especially if it’s about the future …”<br />
At “The Grain” we strongly believe that<br />
combining artificial and human intelligence<br />
is key for future success of both our<br />
industry and humanity, hence our wellbeing<br />
and our welfare. The role of people<br />
will remain strategic, only the content of<br />
our jobs will change. Thanks to technology<br />
we can get rid of repetitive and often boring<br />
routine work, in many cases leading to malpractices,<br />
and concentrate on rewarding<br />
and true valuable input. Or to put it simple,<br />
“We are for questioning, AI for answering”.<br />
Einstein already stated it clear: “If I had an<br />
hour to solve a problem, I'd spend 55 minutes<br />
thinking about the problem and five<br />
minutes thinking about solutions.” Hence,<br />
Technology provides the know-how, humans<br />
the know-why.<br />
The most important impact of technology<br />
is how it changes people. Therefore,<br />
it is at its best when it brings people together<br />
and services our purposes! Hence,<br />
we should not be concerned about the exponential<br />
change in artificial intelligence<br />
or robotics, but more about the stagnant<br />
attitude in human intelligence. Beware<br />
however, it is not the robots taking over,<br />
but it is the men who play with toys that<br />
are to be feared. That’s were ethics enters<br />
into the equation. Technology is ethically<br />
neutral, until wrongly applied by us!<br />
Let us embrace technology and use it for<br />
the right purpose with a clear anthropocentric<br />
focus, i.e. for the use and benefit<br />
of humanity and in this case our maintenance<br />
engineers, operators and asset<br />
managers in general. Allow me to quote<br />
Einstein once more, confirming that indeed<br />
nothing really changes: “Why does<br />
this magnificent applied science which<br />
saves work and makes life easier bring us<br />
so little happiness? The simple answer<br />
runs: Because we have not yet learned to<br />
make sensible use of it.”<br />
Well dear Albert, we might get there.<br />
Humans will remain human, technology<br />
will just leverage our skills, if done<br />
right! Man, and machine will keep living<br />
and working side by side like they’ve<br />
done for ages, but now for the better. AI<br />
will provide answers and insights to our<br />
questions in maintenance, process and<br />
organisation. Thanks to AI, we have the<br />
opportunity to embrace that necessary<br />
change. We are heading for a renewed<br />
era of Uber-anthropocentrism, unlocking<br />
human potential and driving a new<br />
industrial renaissance. Human ingenuity<br />
will excel!<br />

ASSET MANAGEMENT<br />
Measurement Traceability for<br />
the Controlled Environment<br />
JUSTIN WALSH, Business Development Engineer, Vaisala Inc.<br />
The measurement of environmental<br />
conditions is increasing<br />
in relevance and influence<br />
in industry. As efficiency<br />
standards and capabilities<br />
continue to evolve, these<br />
conditions are being better<br />
monitored and controlled to<br />
optimize performance in a<br />
number of applications. The<br />
amount of information available<br />
and its use for analytics is<br />
growing exponentially, making<br />
it more important than<br />
ever to base decisions on accurate<br />
and reliable data.<br />
SOMETIMES OVERLOOKED or taken<br />
for granted, the data from environmental<br />
sensors for parameters such<br />
as relative humidity, temperature and<br />
carbon dioxide provide powerful control<br />
understanding to the operations<br />
they serve. Relevant examples are data<br />
centers, who rely on accurate humidity<br />
and temperature measurement to<br />
protect their IT infrastructure, as well<br />
as the CO2 sensors responsible for the<br />
efficiency and agility of a Demand Controlled<br />
Ventilation (DCV) system in a<br />
school or office. While the general task<br />
of these sensors is not especially difficult,<br />
problems from sensor failure or<br />
inaccuracy can have a large impact on<br />
critical operations. Measurement underperformance<br />
can lead to decreased<br />
efficiency, non-compliance of operating<br />
conditions, unplanned down-time,<br />
or production loss.<br />
Maintaining accurate measurements<br />
is the key to long-term operational efficiency,<br />
and Computerized Maintenance<br />
Management Systems (CMMS) can use<br />
sensor data from more locations and in<br />
greater detail than ever before. Incorporating<br />
environmental sensor data<br />
into these systems and others, such as a<br />
digital twin, or Industry 4.0 and IoT networks,<br />
affect the analytics and predictive<br />
indicators that we gain from those systems.<br />
This places more responsibility on<br />
the measurements from these sensors,<br />
and our efforts to maintain them to a<br />
high standard.<br />
Information from the calibration of<br />
humidity, temperature and CO2 sensors<br />
can be tracked to provide insight into<br />
sensor health and stability that will improve<br />
preventive maintenance schedules<br />
and to help mitigate risk. Digitalization<br />
of these operations relies on data from<br />
36 maintworld 2/<strong>2021</strong>
ASSET MANAGEMENT<br />
sensors whose readings will inherently<br />
drift in their accuracy, requiring calibration<br />
and adjustment to maintain peak<br />
performance.<br />
Calibration ensures<br />
data integrity<br />
All measurement sensors are going to<br />
lose accuracy over time, through normal<br />
continuous use or environmental<br />
influences. One of the best ways to understand<br />
an instrument’s measurement<br />
performance is to assess its accuracy, and<br />
calibration is the only way to definitively<br />
determine how accurate these instruments<br />
are. During calibration, it is determined<br />
how much, if at all, the measurement<br />
deviates from a defined reference,<br />
and adjustments can be made to preserve<br />
measurement accuracy, and quality data.<br />
The maintenance activities for some<br />
of these sensors can pose challenges of<br />
their own, as it can be inconvenient or<br />
impossible to remove and send an instrument<br />
to a calibration lab for service.<br />
In many cases it is preferred to calibrate<br />
in-situ with a spot-check or in-house<br />
calibration laboratory. An example of<br />
this is in cleanrooms, where the transport<br />
of equipment in and out of the<br />
space is a time-consuming process. Difficulty<br />
lies in performing that calibration<br />
or adjustment to a high standard,<br />
as not all calibration tools are the same,<br />
and the quality of references is of decisive<br />
importance.<br />
The right tool for the job<br />
Portable reference equipment can<br />
provide a versatile and cost-effective<br />
way to maintain sensors at a high<br />
level by using them as transfer standards.<br />
They can be of high accuracy<br />
that meet or exceed the unit being<br />
evaluated and maintain traceability<br />
to international standards. Transfer<br />
standards are used to transfer a<br />
measurement parameter from one organization<br />
to another, from a primary<br />
standard to a secondary standard, or<br />
from a secondary standard to a working<br />
standard in order to create or<br />
maintain measurement traceability.<br />
Traceability is the relating of<br />
the measurement back to the international<br />
system of units (SI units)<br />
through an uninterrupted chain of<br />
comparisons, all with stated uncertainties.<br />
Establishing a high degree of<br />
confidence in the measurement becomes<br />
even more important for portable<br />
instruments, as their accuracies<br />
ONE OF THE BEST WAYS<br />
TO UNDERSTAND AN<br />
INSTRUMENT’S MEASUREMENT<br />
PERFORMANCE IS TO ASSESS<br />
ITS ACCURACY.<br />
do not often exceed that of the units<br />
under test. It is very difficult and expensive<br />
to maintain reference equipment<br />
of higher accuracy than many<br />
high end humidity, temperature, barometric<br />
pressure, and CO2 sensors<br />
for occupied condition monitoring.<br />
They are likely to be a 1:1 comparison,<br />
or slightly better, but rarely meeting<br />
the traditional 4:1 test accuracy ratio.<br />
Therefore, it is of great importance<br />
that your instrument be calibrated<br />
against an SI-traceable reference to<br />
ensure the quality of measurement<br />
data. Additionally, proper procedure<br />
and best practices must be followed,<br />
because even the best reference used<br />
improperly can degrade accuracy.<br />
Further increasing the trustworthiness<br />
of a traceable calibration<br />
is the accreditation of the service<br />
provider that has calibrated the reference<br />
standard or transfer standard.<br />
ISO/IEC 17025 accredited calibration<br />
service providers have been certified<br />
to provide traceable calibrations with<br />
detailed uncertainty information,<br />
proper environmental conditions,<br />
and methods by competent personnel.<br />
In order to ensure these high<br />
standards, these laboratories are audited<br />
regularly.<br />
Assessing traceability<br />
How do you know if your instrument is<br />
indeed SI-traceable? One way is to study<br />
its calibration certificate. For example,<br />
the following information should be<br />
available:<br />
1 Calibration results include measurement<br />
uncertainties<br />
2 All calibration references are identified<br />
3 Notes on how uncertainties are<br />
determined and what uncertainty<br />
sources are included<br />
4 Description of how the SI traceability<br />
was established<br />
5 Reference and ambient conditions<br />
Conclusions<br />
The more important and integrated<br />
the sensor data is to your operation,<br />
the greater the assurance is needed<br />
for that data to be accurate and verifiable.<br />
It is encouraged that equipment<br />
and facility managers select the best<br />
methods and providers when planning<br />
their calibration and maintenance<br />
activities.<br />

05-Steps to Develop Drilling<br />
Organization Asset Integrity<br />
Management Program<br />
Asset Integrity is the ability of an asset to perform its function effectively<br />
and efficiently throughout its lifecycle while safeguarding life and the<br />
environment. In other words, an asset in question is required to perform its<br />
intended function as per the design intent. An Asset Integrity management<br />
system is about taking care of the aspects of people, processes and<br />
equipment interaction effectively to achieve the design intent of an asset.<br />

ASSET MANAGEMENT<br />
AN ORGANIZATION SHOULD DEVELOP A UNIFIED CORPORATE ASSET INTEGRITY MANAGEMENT FRAMEWORK<br />
BASED ON ASSET MANAGEMENT, INSPECTION, MAINTENANCE & OPERATION REQUIREMENTS.<br />
A MAJOR ACCIDENT HAZARD (MAH) is the<br />
failure of one or more factors related to<br />
people, process and equipment. To achieve<br />
an effective asset integrity, the organization<br />
needs to have more focus on major accident<br />
hazards as these incidents are rare, but the<br />
consequence is large. Drilling operations<br />
are exposed to a number of hazards such as<br />
corrosion, fatigue, accidental damage, extreme<br />
weather conditions, geological, geotechnical,<br />
change in used technology etc.<br />
throughout their life cycle which may lead<br />
to a major accident. Drilling operation may<br />
also have additional complexities due to the<br />
involvement of many stakeholders, such<br />
as drilling contractor, drilling equipment<br />
supplier, operator etc. It therefore becomes<br />
more important for drilling to develop a<br />
structured asset integrity management<br />
program where the proper integration of<br />
different stakeholders is established with<br />
clear roles defined to reduce the probability<br />
of hazard realization from a major accident<br />
hazard (MAH). This brings the organization<br />
focus on managing the people, process<br />
and equipment/machinery-related weakness<br />
to avoid the MAH and ensures that the<br />
asset functions as per the design intent.<br />
In this article, A 05-step process is suggested<br />
to develop an overall Asset Integrity<br />
Management program for a drilling organization<br />
to manage a Major Accident Hazard<br />
threat and its realization.<br />
The operation of a drilling company is<br />
more complex as several stakeholders, such<br />
as operator (drilling, reservoir, geological,<br />
operations team), Drilling service companies<br />
(drilling fluids, cement, BOP manufacturer,<br />
well casing design, drilling bits<br />
etc.), classification societies and Drilling<br />
company/contractor (Rig design & maintenance,<br />
driller, rig crew etc.) are involved<br />
in achieving the common goal of drilling.<br />
Due to the very nature of a drilling operation,<br />
the organizations need more focus on<br />
major accident hazards as these incidents<br />
are rare, but the consequence is large. A<br />
major accident hazard is the failure of one<br />
or more factors related to people, process,<br />
and equipment. While drilling organisations<br />
manage control and critical drilling<br />
equipment well, based on proponent<br />
in-house standard and/or international<br />
standard such as API/ISO, the complexity<br />
and various stakeholder involvement often<br />
lacks the availability of a structured asset<br />
integrity program to manage the major accident<br />
hazard. An asset Integrity Management<br />
Program in any organization requires<br />
the integration and utilization of company/<br />
stakeholder’s internal process, procedure,<br />
standard & guidelines and tools e.g. forms,<br />
checklist etc. for proactive control & mitigation<br />
of a major accident hazard.<br />
In this paper, A simplified 05-step process<br />
is proposed for a drilling organization<br />
to develop an organization-specific Asset<br />
Integrity Management program.<br />
Step 1- Development of<br />
Asset Integrity Management<br />
Framework<br />
An organization should develop a unified<br />
corporate Asset Integrity Management<br />
framework based on asset management, inspection,<br />
maintenance & operation requirements.<br />
The framework should detail the<br />
integration of a drilling company/contractor<br />
internal process/procedure and other<br />
stakeholder process/procedure to achieve<br />
avoidance/mitigation of a major accident<br />
hazard.<br />
The framework should define the people,<br />
process and equipment/system integrity<br />
requirements to avoid a potential major accident<br />
hazard by evaluating following basic<br />
aspects e.g.<br />
• Do we understand what can go wrong?<br />
• Do we know what systems are in place<br />
to prevent this from happening?<br />
• Do we have assurance and verification<br />
functions that these systems will work?<br />
• Do we have proactive visualization of<br />
integrity performance based on leading/lagging<br />
KPI?<br />
Based on the evaluation of the above<br />
aspects, the framework should include<br />
a high level requirement of the following<br />
Integrity management element<br />
2/<strong>2021</strong> maintworld 39
ASSET MANAGEMENT<br />
• Policy for Asset Integrity Management<br />
and utilization of any current/<br />
existing management system to ensure<br />
Asset Integrity<br />
• Structure & governance of asset<br />
integrity management to effectively<br />
manage the asset integrity related to<br />
activity and function<br />
• Identification of barrier and its<br />
component e.g., key competency,<br />
safety critical element (equipment/<br />
component/system), critical process<br />
/ procedure, interface requirements<br />
for drilling service and function.<br />
• Development of Assurance-function<br />
based on existing operation, engineering,<br />
technical, maintenance<br />
requirements<br />
• Verification requirements/activity<br />
based on regular review of current<br />
integrity status (Use existing forms/<br />
checklist, program to the maximum<br />
extent)<br />
• Visualization of existing rig integrity<br />
status based on identified Safety<br />
critical element (SCE) integrity status<br />
and current status review<br />
• Performance monitoring based on<br />
leading and lagging KPI related with<br />
asset integrity management.<br />
Step 2- Develop Asset<br />
Integrity Management<br />
Structure<br />
Drilling company/contractor should ensure<br />
that the existing management program<br />
provide the integrity management<br />
structure and function to specifically<br />
support the verification of safety critical<br />
equipment/element (SCE) assurance<br />
functions to avoid/mitigate MAH. This<br />
should include an asset Integrity Management<br />
team both at corporate/site<br />
level with details RASCI (responsible,<br />
accountable, support, consultative and<br />
information) chart to execute the Integrity<br />
management specific task leading to<br />
adequate focus on major accident hazard<br />
and related risk realization.<br />
The company should create an Identify<br />
Asset Integrity Management/Engineering<br />
team, and assign responsibilities<br />
to address specific asset integrity-related<br />
activity/task such as:<br />
• Development, execution and monitoring<br />
of asset integrity management<br />
specific internal procedure & guide<br />
• Operational risk management guide,<br />
risk register development and utilization<br />
of risk register as a tool to<br />
manage the risk.<br />
• Development & utilization of Well<br />
barrier schematic for different types<br />
of Well, and an area to support asset<br />
integrity<br />
• Evaluation of MHA related safety<br />
critical task analysis (SCTA) and its<br />
effectiveness through assurance &<br />
verification process to minimize human<br />
error.<br />
• SCE (people, process, equipment/<br />
system) identification and its management<br />
based on SCE performance<br />
standard development, execution<br />
& update. Below is a list of some required<br />
performance standard examples<br />
• Well test and control<br />
• Blow out preventer system<br />
• Choke & Kill system<br />
• Rig move & structure<br />
• Main power system & supply<br />
• Emergency power system & supply<br />
• Fire and gas detection<br />
• Third party equipment<br />
• Emergency shutdown system<br />
• Lifting Equipment<br />
• Execute, verify & monitor SCE integrity<br />
assurance based on existing<br />
Inspection, Maintenance, testing<br />
(IMT) and operating procedures<br />
• SCE (both hardware and software)<br />
Performance monitoring and continuous<br />
improvement<br />
Step 3- Create effective risk<br />
management process to avoid<br />
Major Accident hazard<br />
The organization should develop a decision<br />
support flow diagram with inbuilt<br />
action details for all the key causal risk of<br />
any major hazardous event (Refer Figure-1)<br />
to develop an effective risk management<br />
for asset integrity. This flow diagram<br />
will provide the necessary insight<br />
about the inclusion of required assurance<br />
and verification task related with process,<br />
people and equipment in the applicable<br />
performance standard of identified SCE.<br />
To have a detailed insight about the<br />
availability of control, and mitigation<br />
barrier of an identified causal risk, an<br />
organization can use other safety study<br />
tools such as SWIFT (Structured what<br />
if technique), Bow-tie analysis etc. The<br />
generated information can be used to<br />
develop a risk register at rig level with<br />
existing control and mitigation details<br />
on all the operation, process, mechanical,<br />
and people-related causal risks. The<br />
developed risk register can be aligned<br />
with the overall ERM (Enterprise Risk<br />
Management) process of the organization<br />
and used as a tool for SCE integrity<br />
management with focus on control &<br />
mitigation effectiveness. A risk tracking<br />
system should be available to monitor<br />
the status of identified risk based on the<br />
listed control & mitigation barrier/SCE<br />
effectiveness. The risk management<br />
process should define a clear RASCI<br />
(Responsible, Accountable, Support,<br />
Consultative and Information) chart for<br />
the employee/management and devise<br />
a mechanism to review and update the<br />
identified risk on a regular basis.<br />
Step 4- Establish Asset<br />
Integrity Model Barrier and<br />
SCE management process<br />
Drilling company/contractors should<br />
develop a barrier model for people, process<br />
and Well control/critical equipment<br />

ASSET MANAGEMENT<br />
(both well and rig related) in some form of<br />
barrier model to have visibility and clarity<br />
of any hazard/threat realization concept<br />
across the organization. It is worth mentioning<br />
that the representation of hardware<br />
equipment/SCE in the form of a rig<br />
barrier along with Well barrier schematic<br />
(for hardware & software) will provide the<br />
required visualization of a hazard/threat<br />
as an integrity model being followed by the<br />
subject organization operation.<br />
Shown below (Figure-2) is a typical<br />
barrier concept based on the swiss cheese<br />
model which represents the hardware<br />
(equipment) flaws for hazard and threat realization<br />
being followed for Asset Integrity<br />
Management as an AIMS Model representation<br />
for a process plant. Drilling organizations<br />
can develop a similar AIMS model as<br />
applicable.<br />
Further, organizations should develop<br />
a clear process for SCE identification and<br />
its review/update process for the effective<br />
monitoring of a Major accident hazard. A<br />
Safety Critical Element (SCE) is defined<br />
as a system, Item of equipment, Person or<br />
Procedure that is specifically identified<br />
using HEMP (Hazard effect management<br />
process) and included in the facility Safety<br />
Case (highly recommended to develop for<br />
drilling organization) as an asset that:<br />
• Failure of which could cause or<br />
contribute substantially to a Major<br />
Accident or Major Environmental Accident;<br />
and/or<br />
• Purpose of which is to prevent or limit<br />
the effect of a Major Accident or Major<br />
Environmental Accident.<br />
Once an SCE has been identified, the organization<br />
should align the identified SCE<br />
(hardware & software) with any operational<br />
risk as captured in the risk register and<br />
develop a barrier & related safety critical<br />
equipment/system performance standard<br />
based on key IMT (Inspection, Maintenance<br />
& Testing) and operational assurance<br />
activity, to avoid the risk realization.<br />
A performance standard defines the<br />
critical function, specific, verifiable, realistic<br />
and achievable performance requirements<br />
with which the SCE shall comply<br />
throughout the lifecycle of the installation.<br />
It can be expressed in qualitative or quantitative<br />
terms, but should produce a Pass<br />
or Fail result, which is used as the basis for<br />
managing the hazard.<br />
A barrier/SCE management process<br />
should utilize a performance standard,<br />
its verification and reporting along with<br />
other activity based on a PDCA (Deming<br />
cycle) concept. This process should<br />
include all the required instruction and<br />
linking of existing process/procedure,<br />
along with the roles & responsibilities of<br />
the Asset Integrity assurance team, the<br />
OME team and the Asset integrity verifier.<br />
All the identified barrier/SCE should<br />
be verified against these performance<br />
standards to ensure its integrity.<br />
A typical SCE management flow diagram<br />
(Figure-3) based on performance<br />
standard is depicted below for reference.<br />
Step-5 Identify leading and<br />
lagging asset integrity specific<br />
KPIs and develop Asset<br />
Integrity dashboard<br />
The identification of leading and lagging<br />
indicators are key to managing the organization<br />
asset integrity performance factors<br />
proactively that are responsible for major<br />
accident hazard realization e.g. the lack of a<br />
risk management process, deficiency in internal<br />
procedure & guidelines, lack of barrier/safety<br />
critical element management<br />
and lack of compliance audit & verification.<br />
On many occasions, clear boundaries in<br />
a leading and lagging indicator are fuzzy. A<br />
gas kick for example, is a leading indicator<br />
for a possible blow out, whereas it is a lagging<br />
indicator for well bore fluid that has<br />
already entered the well bore due to a barrier<br />
failure.<br />
A leading indicator is considered to<br />
be a predictive set of parameters/course<br />
of action which delivers early information<br />
on barrier performance. It must be<br />
measurable and recognizable and provide<br />
benchmark operation & organization performance<br />
for asset integrity management.<br />
Lagging to leading events for drilling<br />
operation can be presented as progression<br />
arrow define by Nafiz Tamim et. al. (2016)<br />

Organizations should develop a process<br />

Organizations can further evaluate<br />
and adopt the below KPI as applicable for<br />
Asset Integrity performance monitoring.<br />
• Corporate level lagging KPI “Asset<br />
Integrity Index” based on rig level<br />
integrity related KPIs e.g., corrosion<br />
management, process & procedure<br />
Compliance, gas kick, BOP, well control<br />
etc.<br />
• Leading KPIs related with SCE management<br />
and its integrity status<br />
• Number of processes & procedures<br />
in compliance<br />
• Number of anomalies related with<br />
barrier/SCE that were not closed out<br />
by the planned due date at the end of<br />
each quarter<br />
• Number of barrier/SCE not meeting<br />
performance standard<br />
• Number of activations of barrier/<br />
SCE e.g., gas kick<br />
• Number of barrier/SCE past a<br />
planned completion date (barrier/<br />
SCE backlog)<br />
• Number of barrier/SCE did not<br />
follow MOC process<br />
Based on KPI monitoring, an organization<br />
should develop a dashboard for the<br />
clear visualization and reporting of all the<br />
identified SCEs, and an overall integrity<br />
status.<br />

safety critical element based on the swiss<br />
cheese model is represented below in<br />

Conclusion<br />
Establishing a structured asset integrity<br />
management program is key to managing<br />
a major accident hazard. Using the<br />
05-step process as detailed in this paper,<br />
an organization can develop a drillingspecific<br />
asset integrity program to<br />
achieve excellent performance in overall<br />
asset management, while addressing the<br />
avoidance and mitigation of a major accident<br />
hazard.<br />

Infrastructures Physical Assets High<br />
Performance Achievement based on<br />
Reliability and Maintenance Program,<br />
A.I and Asset Integrity Management<br />
Nowadays the world invests around $2.5 trillion a year in infrastructure physical<br />
assets such as transportation, power, water, and telecom systems on which businesses<br />
and populations depend. Yet this amount continues to fall short of the world’s everexpanding<br />
needs, which results in lower economic growth (MGI’s 2013 report).<br />
INDEED, THE ECONOMIC CRISIS IN 2008 already<br />
led to enormous spending cuts across<br />
the globe. In Europe, the post-war infrastructure,<br />
especially bridges, is ageing. Despite<br />
that, the maintenance backlog, i.e., the<br />
amount of maintenance and rehabilitation<br />
that should have been completed in order to<br />
maintain infrastructures in good condition<br />
but has been deferred, is growing considerably.<br />
This problem could be being amplified<br />
because of the COVID-19 Pandemic, that<br />
causes further service cancellations, delays<br />
and consequently spending cuts.<br />
This article aims to demonstrate the<br />
importance to implement the reliability and<br />
maintenance program during infrastructure<br />
concept and design phase, as well as A.I<br />
integrated to Asset Management and Asset<br />

2 – Reliability and<br />
Maintenance Program for<br />
Infrastructure<br />
The maintenance activities applied to infrastructures<br />
physical assets need to be under<br />
the context of a Maintenance Program, that<br />
considers different reliability engineering<br />
methods to be implemented throughout<br />
the different life cycle phases from concept<br />
to the decommissioning phases.<br />
The Reliability Centred Maintenance<br />
(RCM) is a method initially applied<br />
during the design phase, that aims<br />
to define the maintenance tasks based<br />
on the infrastructure failure modes,<br />
causes and effects as well as the associated<br />
risk. The information that is input<br />
in order to perform the RCM are the<br />
infrastructure’s failure mode and effect<br />
analysis (FMEA). In the Railway Industry,<br />
the infrastructure’s systems play an<br />
important role in terms of the safety and<br />
performance of the railway. One good<br />
example is the rail component that in<br />
44 maintworld 2/<strong>2021</strong>
ASSET MANAGEMENT<br />
case of failure, will trigger impact on a<br />
Railway System’s operational availability<br />
and may trigger a major accident such as<br />
derailment as shown in figure 1.<br />
Figure 1 describes the rail RCM where<br />
the risks are assessed as intolerable based<br />
on the combination of the cause frequencies<br />
and the consequence severity. Based<br />
on such assessment, different maintenance<br />
task types and the frequencies at<br />
which they are carried out are defined to<br />
mitigate the risk, such as Visual inspection<br />
and Track Road Vehicle Inspection<br />
(Ultrasonic Test). Similar methods comparable<br />
to the RCM approach is the RBI.<br />
The Risk Based Inspection (RBI)<br />
is applied initially in the design phase<br />
and later during the operation phase.<br />
The RBI Infrastructure scope focuses<br />
on a failure that can trigger a major<br />
accident. The RBI method is implemented<br />
based on specific procedures<br />
and standards such as: API 580, API 581<br />
and EN 1691, which can be qualitative<br />
or semi-quantitative based on the RBI<br />
application levels.<br />
In addition to qualitative methods,<br />
it is important to have quantitative<br />
analysis to predict the Infrastructure<br />
Physical Assets RAM performance such<br />
as Lifetime Data Analysis, also popular<br />
known as Weibull Analysis, RAM<br />
Analysis and Reliability Growth<br />
Analysis. These methods can be applied<br />
to assess, verify and validate the infrastructure<br />
system’s RAM performance.<br />
However, the Probabilistic Degradation<br />
Analysis (PDA) is more<br />
appropriate to predict such an infrastructure’s<br />
reliability performance. The<br />
PDA aims to define the infrastructure’s<br />
physical asset reliability based on integrity<br />
degradation failure data related<br />
to the thickness of a crack, corrosion<br />
and erosion measured by non-destructive<br />
test methods. By applying these<br />
methods, it is possible to predict when<br />
the functional failure will be achieved<br />
based on the trend of degradation such<br />
as thickness or depth (Crack or Corrosion)<br />
and by considering the degradation<br />
limit as shown in figure 2.<br />
The pink line 1.5 mm in figure 2 is the<br />
limit of corrosion, where a functional<br />
failure is expected to occur. The other<br />
different lines are different measurements<br />
that predict the trend of the<br />
evolution of corrosion a different points<br />
in time. Therefore, if we project the<br />
interception of each of these lines with<br />
the straight line (1.5 in Y axis) in x axis,<br />
there will be different times of functional<br />
failures. These functional failure times<br />
are used to predict the reliability and<br />
the failure rate function. Based on such<br />
information it can be defined when the<br />
inspection needs to take place.<br />

3 - Maintenance 4.0 applied<br />
for infrastructures.<br />
Artificial Intelligence (A.I) aims to enable<br />
a machine to think and make its<br />
own decisions based on data collected<br />
and assessed automatically without<br />
any human intervention. Based on the<br />
EFNMS – European Committee Maintenance<br />
4.0 (ECM4.0) <strong>2021</strong>, Industry 4.0<br />
is a new paradigm and the last industrial<br />
revolution, that has been implemented<br />
across the globe intensively in the past<br />
five years and is supported by the utilization<br />
of Enabling Digital Technologies<br />
named 4.0.<br />
Concerning the application of A.I for<br />
Infrastructures Physical Assets, machine<br />
learning is applied for the equipment<br />
criticality and critical alert levels classification,<br />
failure regression predictions and<br />
the automatic application of the Prognostic<br />
Health Management (PHM). In<br />
the case of an Infrastructure system, the<br />
stress factors measured by sensors are<br />
vibration, voltage, temperature, humidity;<br />
Non-destructive test measurements<br />
are also taken such as crack thickness,<br />
corrosion depth and other physical parameter<br />
that lead equipment degrade to<br />
functional failure.<br />
The Deep Learning (DL) methods, a<br />
special type of Machine Learning, can<br />
also be applied to support the preventive<br />
maintenance of an Infrastructure<br />
System. The DL is a more sophisticated<br />
machine learning method, that applies a<br />
deep neural network that encompasses<br />
2/<strong>2021</strong> maintworld 45
ASSET MANAGEMENT<br />
several hidden layers as shown in figure<br />
3. The principles of Deep Neural network<br />
consider different layers such as Convolution<br />
Layer, Pooling Layer, ReLu, Fully<br />
Connected, Softmax and the output image<br />
classification. (https://www.eduardocalixto.com/paper-<strong>2021</strong>/)<br />
Despite the advantage of applying A.I<br />
Deep Machine Learning and other A.I<br />
methods as well as reliability engineering<br />
methods, it is necessary to integrate such<br />
methods in an Enterprise Asset Management<br />
System. This will enable the management<br />
of the preventive maintenance<br />
tasks defined for all these methods and<br />
will ensure that the proper resources are<br />
allocated in the proper time to mitigate<br />
the Infrastructure Physical Asset risk of<br />
unavailability along time and the possibility<br />
of a major accident. The next item will<br />
discuss the Asset Integrity Management<br />
as part of the Asset Management.<br />
4 - Infrastructure Asset<br />
Integrity Management (AIM)<br />
An Infrastructure Physical Asset integrity<br />
failure may lead to unavailability, or a major<br />
accident with multiple fatalities. Therefore,<br />
the so-called safety critical elements (SCE)<br />
are the physical assets, which in case of failure,<br />
may lead to a major accident such as jet<br />
fire, toxic cloud release, explosion, fire, toxic<br />
product spill, aircraft crash, trains collision<br />
or derailment. In fact, a major accident can<br />
be triggered by Infrastructure integrity failure,<br />
software, hardware or human error or a<br />
combination of such factors.<br />
In order to mitigate such risks of a major<br />
accident it is necessary to implement a<br />
Reliability & Maintenance (R&M) Program<br />
immediately at the first stage of the concept<br />
and design of a physical asset’s life cycle and<br />
implement all recommendations from such<br />
R&M methods. After that, it is necessary to<br />
implement the risk management and inspection<br />
& test program concerning the A.I<br />
technologies during the operation phase.<br />
The Asset Integrity Program can apply<br />
the same elements of the AM defined in ISO<br />
55000 such as context of the organization,<br />
leadership, planning, support, operation,<br />
and performance evaluation but needs to<br />
focus on the critical safety elements management.<br />
Since 2010, the new era of Industry 4.0<br />
has become a reality for many industries<br />
across the globe. In the last five years new<br />
IOT technology development has been<br />
integrated with EAM solutions concerning<br />
technologies such as Big Data, PHA and Machine<br />
Learning, Reliability 4.0 and the usual<br />

maintenance management routine.<br />
Despite all development that enables<br />
integrated AM, too much focus has been<br />
given to availability performance and<br />
maintenance, with a lack of effort for safety<br />
concerning the safety critical element<br />
management.<br />
However, it is very important to establish<br />
a process to enable an effective AIM<br />
flow integrated to the AM process. Figure<br />
4 describes the AM and AIM flow, highlighted<br />
in green, as part of the AM flow. In<br />
the case of AIM, safety management takes<br />
place in the fourth step, which encompasses<br />
the safety routine management<br />
(safety meeting and incident reports)<br />
as well as the Barrier Management. The<br />
Safety Barrier model is part of the barrier<br />
management that defines the level of risk<br />
of each SCE automatically, based on real<br />
online data.<br />
Since the SCE is defined based on previous<br />
risk analysis considering severity<br />
criticality, the Risk Management of such<br />
SCE performed by the Barrier Model is<br />
automatically updated, enabling Asset Integrity<br />
and helping Safety managers manage<br />
the risk of the SCE on a daily basis.<br />
The Infastructure’s Physical Assets<br />
need to have in the end, all information<br />
integrated in an EAM that encompasses<br />
the best A.I technologies and reliability<br />
engineering methods to enable the leaders<br />
to make a fast and reliable decision.<br />

Data-driven Spare Parts Management<br />
Management of spare parts and other materials<br />
needed for realization of maintenance processes<br />
is one of the key functions in physical asset<br />
management. Especially in power generation, oil<br />
and gas and heavy chemical industries, spare<br />
parts inventories can easily add up to tens<br />
of thousands of various items, in a value of<br />
hundreds of millions of euros.<br />
EFFICIENT SPARE PARTS inventory management<br />
can have significant impact on the<br />
financial performance of the company. Better<br />
spare parts management can lead to improvement<br />
of financial performance of the<br />
company. Spare parts inventory can lock<br />
in significant amounts of working capital.<br />

for effective spare parts inventory management<br />
and spare parts optimization using<br />

1 Eight rules of good spare<br />
parts management<br />
In our previous research, we refined the<br />
following eight rules – best practices – for<br />
good spare parts management:<br />
1) Focus on preventive maintenance<br />
– for preventive maintenance no<br />
inventories of spare parts need to<br />
be held.<br />
2) Solve problems in spare parts processes.<br />
3) Segment your spare parts portfolio.<br />
4) Evaluate spare parts criticality.<br />
5) Apply suitable forecasting methods<br />
and verify their accuracy and reliability.<br />
6) Use special methods for intermittent<br />
demand items.<br />
7) Treat your master data well: Identification<br />
and naming of spare parts<br />
8) Consider the whole lifecycle of your<br />
assets while making decisions related<br />
to spare parts.<br />
In this issue of <strong>Maintworld</strong> we will focus<br />
on forecasting – the essential element in<br />
inventory management. Follow the rules<br />
5 and 6 to apply suitable forecasting<br />
methods and use special forecasting<br />
methods for spare parts with intermittent<br />
consumption. Add rule 7 to improve<br />
identification and naming of your<br />
spares in master data.<br />
Spare parts management starts<br />
with good forecasting<br />
The next step in the specification of<br />
optimum spare parts inventory management<br />
regime is the prediction of future<br />
consumption of the items in stock. The<br />
forecast is always based on transactional<br />
data from information systems – history<br />
of spare parts consumptions, which must<br />
be representative (meaning sufficiently<br />
long). In the case of spare parts, we usually<br />
work with a history of three to ten years<br />
(depending on industry). Three years of<br />
recorded history seems to be the minimum<br />
for intermittent items. A general<br />
rule here applies: the longer the history,<br />
the better and more reliable the forecast.<br />
When analyzing historical consumption,<br />
we need to carefully distinguish between<br />
material consumed for planned maintenance<br />
(planned shutdowns, turnarounds,<br />
preventive maintenance) and spare parts<br />
issued for unplanned (corrective) maintenance<br />
– repairs. In forecasting, we must adjust<br />
the history for planned maintenance.<br />
In the forecasting process, items should<br />
be treated individually, according to the<br />
character of their consumption. Items with<br />
common demand patterns (high runners<br />
– fast moving items like fasteners, etc.) can<br />
be forecast using a number of standard statistical<br />
methods normally used in inventory<br />
management (moving average, exponential<br />
smoothing, Holt’s exponential smoothing,<br />
trends, seasonal indexes, Winter’s method,<br />
etc.). Items with intermittent demand require<br />
a special suitable method to be applied.<br />
The use of standard methods of prediction<br />
and inventory management in case of intermittent<br />
items results often in a substantial<br />
overestimate of future consumption and<br />
therefore excessive inventory level.<br />
Figure 7: Intermittent demand in maintenance (item: Spiral sealing DN25-40 RF)<br />
Intermittent demand is the pitfall<br />
of spare parts management<br />
One of the specific problems in spare parts<br />
inventory management is the nature of<br />
spare parts consumption - intermittent<br />
demand. If we analyze the consumption<br />
history of a typical spare part, we find that<br />
the historical consumption in most of the<br />
analyzed periods amounted to zero. Such<br />
infrequent or intermittent demand, usually<br />
with demanded quantity of just a few pieces,<br />
is very typical for spare parts and other<br />
maintenance inventories. An example of<br />
the consumption history of an intermittent<br />
demand item is presented in Fig. 9.<br />
In maintenance, intermittent demand<br />
is quite often combined with long supplier<br />

Figure 9: Validation table with potentially duplicate items found in master data.<br />
leadtimes. For maintenance inventory<br />
management, intermittent demand and<br />
long leadtimes are a tricky complication,<br />
often leading to large overstock. The main<br />
problem with managing and forecasting<br />
intermittent items is that the standard<br />
forecasting methods used for fast moving<br />
goods (for instance moving averages, exponential<br />
smoothing, Holt’s and Winter’s<br />
method, constant or regression models<br />
with seasonal indexes, etc.) simply do not<br />
seem to work for these items. In case of<br />
intermittent consumption, special statistical<br />
methods (such as bootstrapping<br />
or Smart-Willemain method) need to be<br />
applied.<br />
Smart and Willemain (2004) suggested<br />
a stochastic simulation forecasting<br />
method. Using this method it is possible<br />
to specify minimum inventory level (reorder<br />
level) in order to ensure fulfilment<br />
of requirements with target probability<br />
(logistic service level, target of availability).<br />
The method is based on random sampling<br />
from the history of consumption.<br />
In statistics, similar methods are called<br />
bootstrapping.<br />
Besides intermittent items, in a large<br />
maintenance inventory we can also find<br />
fast-moving items with stable and high<br />
regular consumption. These are especially<br />
items of common consumables like fasteners,<br />
generic gaskets, or bearings. For<br />
these items, standard methods of inventory<br />
management and future demand<br />
forecasting can be applied.<br />
Identification of spare parts and<br />
cleaning master data<br />
In spare parts optimization projects, we<br />
quite often face various problems with<br />
quality of spare parts master data – especially<br />
naming: issues with unstandardized<br />
naming or incorrect names, names in various<br />
languages, different word order, typos<br />
etc. hinder significantly all efforts in spare<br />
parts optimization and generally result<br />
in duplicate (or multiplicate) master data<br />
records for identical materials (identical<br />
spare part is stored in several master data<br />
records with different names). In order<br />
to clean spare parts master data, we apply<br />
advanced data analytics on master<br />
data to identify or cluster duplicate (or<br />
similar) items. This key analytical method<br />
is “matching” – comparing names and<br />
certain master data attributes to assess<br />
similarity of spare parts. For this we use<br />
multicriterial comparisons. To analyze<br />
spare parts’ names, metrics like Levenshtein<br />
or Hamming distance are used and<br />
combined with triplets analysis (comparing<br />
all triplets-threes of characters found<br />
in all names in master data).<br />
The result are clusters of similar or duplicate<br />
items found in master data. These<br />
groups of highly similar items are given<br />
to maintenance engineers for validation.<br />
After duplicate items are confirmed, master<br />
data can be rectified – correct items is<br />
selected to be used and all duplicate items<br />
are erased or deactivated. Examples of<br />
Matching are presented in Figure 8 and<br />
Figure 9.<br />
Good spare parts management<br />
has significant impact and benefits<br />
It can be concluded that spare parts<br />
management as a part of physical asset<br />
management has significant impact on<br />
financial statement of the company. Good<br />
spare parts management brings the following<br />
benefits:<br />
• Optimum spare parts quantities are<br />
purchased<br />
• Optimal purchasing cashflow<br />
• Lower inventories<br />
• Less unused inventories<br />
• Higher availability of needed spare<br />
parts<br />
• Good risk management<br />
Various sets of data can be used to support<br />
or optimize spare parts management, especially<br />
in spare parts segmentation, criticality<br />
assessment, forecasting, master data<br />
rectification. The examples demonstrated<br />
in the paper indicate ways to utilize vast<br />
amounts of data available in organizations<br />
today – to monetize the data by improving<br />
efficiency and effectiveness of spare parts<br />
management processes.<br />
