Malta takes Telematics
Freeport Malta is now using a
telematics system to provide information
on vehicle location
for yard planning purposes to
its Navis TOS, and on machine
condition to its IBM Maximo
maintenance and fleet management
software.
Before it was acquired by Cargotec,
Navis had been pushing
into the telematics market, with
an ultimate goal of bringing information
on a vehicle’s location
and its condition together to improve
overall fleet management
and yard planning. Cargotec is
now marketing equipment-based
systems and products under the
Kalmar brand, where they are offered
as a TOS and equipment
OEM agnostic product.
Kalmar has installed GPS units
on 63 terminal tractors and 23
STS cranes at the terminal. The
GPS units are part of an onboard
vehicle controller supplied
by CrossControl, which is now
part of Actuant Corporation and
specialises in controllers for diagnostic
and integrated fleet management
applications.
CrossControl is supplying
Bromma with controllers and
displays for its Green Zone
products. Kalmar is also using
CrossControl’s processor (called
Main Controller) and display
computers in its SmartPort range
of port automation products. At
Malta Freeport Kalmar installed
Main Controller processors
without a display to provide the
GPS position that Freeport uses
as part of its yard planning system.
Malta Freeport is using Navis
PrimeRoute vehicle allocation
and travel optimisation software.
This benefits from “job stepping”,
where the software gets a
message when a particular piece
of equipment has arrived at one
stage in a move, such as underneath
a crane or at the right spot
in an RTG block. Malta Freeport
uses the GPS on STS cranes to
implement geo-fences around
the crane portal so the software
knows instantly when a terminal
tractor arrives under a crane
without having to rely on the
tractor driver hitting a function
key.
Freeport is also implementing
IBM’s Maximo software, which
tracks assets and is used to develop
maintenance schedules to
ensure preventative maintenance
is scheduled and completed. It
also manages spare parts inventory
and can be used to operate a
just-in-time ordering system for
spare parts.
To support Maximo, the Main
Controller connects to the tractors
electronic system via CAN
Bus to collect data, which is then
sent by WiFi to the SmartPort
server. Data on fuel level, engine
hours, coolant level, coolant tem-
TSB in the process mine
Korea’s Total Soft Bank (TSB)
is encouraging terminals to consider
“process mining” as they
look for ways to leverage operational
data to boost productivity.
Data mining is a way of analysing
data to discover hidden correlations
and trends in recorded
events. In a container terminal
context, said TSB, data mining
typically clusters “containers by
cargo type or operator to figure
out average handling time for the
group.” This is useful to some extent,
but is ultimately limited by
the existing statistical functions
of the TOS. It cannot really tell
anything more than the handling
time of various containers broken
down by their attributes, said
TSB.
Where terminals want to dig
into data to try and identify
where they can improve performance
TSB considers “process
mining” is a more useful
approach. “Process mining is a
branch of data mining focusing
more on events and timing,” said
TSB. It examines event logs to
determine a sequence of events
and when they happened.
According to the software
company, container terminals
are ideal for process mining because
they have a TOS to control
cranes and other container
handling equipment. There are
lots of event logs with all the
perature, and oil pressure is then
forwarded on to Maximo every
five seconds.
Freeport Malta is still implementing
Maximo and is not yet
using this information to support
some of its advanced features,
necessary information required,
“like which container has been
handled by which crane at which
time”. Terminals also have a well
defined “priori process model”;
meaning they have clear repetitive
processes and time period
norms against which specific
events can be compared.
“By breaking down the container
handling process via process
mining, we are able to grasp
the average time required between
events and check which
containers are handled over average
time and then try to find
common attributes of containers
or events through data mining
techniques” said TSB. Process
mining requires some expertise
to distinguish important data
from other events and this is
where the experience of a TOS
supplier is needed.
Getting detailed event logs is
obviously important for this type
of process mining. Automated
or semi-automated terminals
where the position of equipment
is known through the crane or
fleet management software have
much more detailed event logs
than conventional terminals. At
conventional manned terminals
equipment positions might only
be recorded intermittently. Typically
a TOS knows equipment
positions only when drivers report
arrival at various points in
like scheduling fuelling dynamically.
So far the main benefits
Malta has achieved from the telemetry
system relate to getting
accurate information in real time.
Freeport is now confident it has
the platform to get the benefits
ICT FOCUS
Malta Freeport is using vehicle telematics to provide real time data to planning and fleet management applications
the task. TSB noted that in these
cases, machine generated data
should be incorporated before
process mining begins.
TSB has used process mining
at the Kao Ming Container
Terminal (KMCT) in Taiwan to
investigate the reasons behind
re-handling moves in its automated
RMG stacks. It collected
information on the re-handling
moves and the re-handled
container attributes over a oneweek
period. Through process
mining TSB identified seven reasons
for re-handling and was able
to suggest improvements to two
specific types of patterns. The
of its investment in Maximo and
planning applications like Prime
Route without having to rely on
manual processes or data entry.
A company spokesperson said
the results so far “are very
encouraging”.
details are confidential but TSB
said the improvements reduced
shuffling moves by between 25%
and 50%.
Chih-Cheng Kao, KMCT
vice president of terminal operation,
said process mining produced
a good result quickly. Its
administrators were able to get
the required data easily and take
immediate action to reduce shuffling.
“[Process mining analysis]
is one of the intelligent analysis
tools for terminal operators to
manage and control job orders
smoothly at the yard and shipside.
Thanks to the instant and reliable
analysis data obtained from
it, we can decrease the shuffling
rate in yard and increase operational
performance immediately
at shipside and yard,” he said.
TSB used process mining to investigate re-handling at Taiwan’s Kao Ming
Container Terminal, which is slated to expand to four berths next year
Do you want to
improve your
crane’s uptime
A majority of container cranes in the world are
equipped with an Alimak service elevator. We have
been successfully servicing the maritime industry
since the 1970’s. More than 2,500 elevators have been
supplied for port cranes since our first delivery in
1971, providing simple, safer and easy access for the
crane driver, which reduces crane downtime and
enhance productivity and profit. Today, Alimak
container crane elevators are installed in more than
90 countries around the world.
