Editor’s note

The collective

KIVI membership

Dear reader,

Today, almost all of us live ‘in the cloud’. Our work, our

conversations, our photo moments - we store everything so we

can access it no matter when and where we are. When

travelling, Google tells you where to find the best restaurants

and hotels and, more recently, where to find the nearest EV

charging station, for example. By the way, that trip was booked

and paid for with one click via a secured app, of course after

extensively comparing the different options and prices.

We are talking about digitalisation. And yes, it has made our lives

easier in many ways. But we are also noticing more and more how

vulnerable we have become at the same time. Think of the spam mail we

receive, but also the feeling that you are being ‘watched’. How often do

you talk about something and then receive advertising about this topic on

your mobile? And even with the use of passwords, hackers still find their way to

your data.

The above can also be translated to the wind industry, in fact to all industries.

Digitalisation opens the door to more optimised and sustainable operations: optimised

operation of assets, time savings, cost savings, emission savings, just to mention a few, but

potentially also safety of those who work in the wind farms.

In this edition, we discuss the status of wind industry digitalisation (p.7) and show

examples of initiatives by existing Dutch players and start-up companies. But the wind

industry is also still relatively new in this area and if the proper measures are not

implemented, this could have a high price. Like Harold Veldkamp of Topsector Energie

says: it is not a question whether you will be hacked but when (see p. 10).

Your employees up to date

Good employership starts with happy employees, who are motivated, challenged and upto-date.

In our present time with technological developments at top speed, innovations and

transformations professional agility is paramount. Would you, as an employer like to make

a structural contribution to the technical development of your employees? Consider a collective

membership at the Royal Netherlands Society of Engineers (KIVI: Koninklij k Instituut

Van Ingenieurs). Sign up ten (or more) of your top engineers and they can immediately

benefit from all advantages the largest engineering platform in the Netherlands has to offer.

But while we welcome new, modern solutions for optimising wind farm operation and all

related activities, we also say goodbye to initiatives that once were also new and innovative.

Currently two large wind energy repowering projects are taking place in the Netherlands.

Scattered, solo wind turbines and small wind farms are making way for clustered, large,

multi-megawatt wind farms. In this edition we discuss the dismantling of the iconic

‘nearshore’ wind farm Irene Vorrink (p. 36) which is making way for the large

Windplanblauw project. We also look back at a once internationally famous Dutch wind

turbine manufacturer NedWind. The last wind turbines can still be viewed...but not for

Smart & efficient vessel operation

While the industry has been digitising production processes for

decades now, the maritime sector is still cautiously taking its

first steps in this area. Dutch start-up company TechBinder

developed the Smart Vessel Optimizer for smarter and more

efficient vessel operations.


Polenko/NedWind: Ode to (almost) gone Dutch glory

With the trend towards concentrated, large-scale,

MW wind farms, older wind turbines are rapidly disappearing.

Windpowernl magazine highlights digitalisation definition, main principles and

benefits for industrialisation and product & process-related optimised lifecycle


Digitalisation as a concept definition covers a wide

range of (industrial) activities, with wide impact at

products and processes from design and

manufacturing to lifecycle upkeep support. It has

also become a key wind industry enabler for speeding up

industrialisation and automation efforts now demand grows fast

and volumes must increase in parallel.

This is also crucial for accelerating energy transition towards a

sustainable power supply based on renewables, and for rapidly

reducing dependence on fossil fuels for curbing climate change

as well as geopolitical reasons. The wind industry besides huge

opportunities faces major supply-chain disruptions, plus huge

cost pressures including steep rises in essential materials.

Early initiatives

Digitalisation at turbine level commenced already over two

decades ago. Early modest initiatives were typically characterised

by putting sensors in prototype gearboxes for testing purposes

and/or in serial produced geared and direct drive drivetrains for

condition monitoring and accumulating operational data.

Siemens Wind Power (Siemens Gamesa) during 1998 introduced

its first condition monitoring system (CMS). It focused at

providing a low-cost solution for simple management of key data

and expansion and refinement over time. The system further

served as a testing platform for envisaged future offshore

application. The initial concept comprised three vibration

analysis accelerometers, known as robust without moving parts,

and mounted at the gearbox, generator and main shaft bearing

respectively. This uncomplicated analytical tool allowed analysts

‘to seeing things’ before they turned into a failure. Data

accumulation and analysis involved rotational speed, frequency

analysis and trend analysis, with a data back-up capability and

fresh opportunities to draw from if something occurred ‘to look

unusual or strange.’

Today’s advanced turbines incorporate many sensors at critical

spots for monitoring operating status and (changes in) relevant

parameters compared to reference values like set after running-in

period ending. Key variables include rotor speed, main

component vibrations and/or operating temperatures and

temperatures inside and outside the nacelle, and blade loads.

Optimal utilisation

Turbine SCADA-based control systems continuously record,

analyse and store incoming signals and regulates turbines such

that energy in the wind is always optimally utilised plus operating

safety ensured. Further common are dual or redundant sensors

for critical components and functions like generator temperature

control and direct drive generator airgap monitoring. If during

operation the first sensor fails, a second similar device takes over

the function instantly.

OEM’s today monitor turbines and wind farms remotely from

dedicated centres with various expertise levels from experienced

technicians up to highly trained experts. These address any issues

from rather straightforward solved by a remote restart to

complex problems that could lead to catastrophic failures

without physical intervention. Data acquisition thus requires in

parallel high-level technical knowledge plus statistical and

analytical skills for adequate data analysis and data


One complex issue explained to me was on a wind farm where

one out of 80 turbines showed much higher nacelle temperature

levels. The experts analysed temperatures in all main

components, possible deviations in component/system vibration

The new Bolt Strain Sensor from Nabtesco helps to

levels, output variations, etcetera. The root cause proved a bird

nest blocking a hatch in the affected turbine responsible for the

peak temperature level.

Finally, data streams must be converted from information into

knowledge for direct utilisation and incorporating in existing

databases with historic datasets on specific main components,

turbine models, plus wind farms in multiple geographical areas.


Digital technology is now almost standard deployed during

development and manufacture of new products and processes.

Gearbox manufacture at ZF Wind Power, for instance, involves

‘digital intelligence’ accumulated on what parts were put inside,

production dates, dimensional characteristics, and stored values

like on individual bolt-torque values. In addition, data collected

during gearbox running-in tests including measurement

recordings on vibration patterns, noise and temperatures. Each

gear inside any gearbox typically has its own unique codes

permanently ‘stamped in.’ In the past by contrast, all such data

had to be written down and filed with inherent risk of human

error and data loss over time. Today, these values are digitally

recorded, saved and safely stored, and distributed to relevant

channels within the company and to third parties when required.

After a finished gearbox has completed all bench testing

procedures, it leaves the factory with a kind of Digital Birth

Certificate. This documentation contains specific details of the

given gearbox’ design supplemented by ‘as-built information’ of

any single unit obtained during product development and

manufacturing. It further serves as a functional interface between

gearbox development & manufacturing and operational phase.

The next digital element or Life Cycle Monitor registers and

stores gearbox performance data obtained from a standard fitted

SCADA system as well as also near-standard CMS.

The combination Digital Birth Certificate and Life Cycle

Monitor merged with in-house expertise on failure modes and

remedying solutions is then integrated in Life Cycle Analytics.

This is an advanced decision-making tool backed by advanced

statistics and provides ‘remaining lifetime predictions’ and

supports alert-based service intervention recommendations.

These in turn substantially contribute to cost-effective optimised

operation and maintenance (O&M) performance. Determining

Consumed Lifetime and Remaining Lifetime and lifecycle

monitoring/analytics are three other advanced digitalisation

options offer as part of an intelligent wind turbine gearbox.

Data analytics is finally key to reduce OPEX by increasing

output and availability, and extend gearbox and turbine

lifetime with reduced LCOE backed by science and experience.


Comparable digital tools and processes are used by other wind

industry parties for storing key data during manufacture/

assembly and on finished products. One example are samples

stored on the composite material of rotor blades, who worked

at what dates on the specific product, eventual issues, etcetera.

Another is in the careful recording and digital storing of bolt

torque values of all hub & pitch-bearing bolts, plus eventually

as well on the employees involved with the task. All these

examples show the huge potential, options and benefits offered

by ongoing digitalisation through traceability of stored data

even during component issues or catastrophic failure events

after years of operation in the field.

Modern industrial development is today distinguished in four

distinct phases, each with specific elements and main

characteristics. A leading turbine supplier recently described

the status of the offshore wind industry regarding

industrialisation and automation levels in between Industry 2.0

and Industry 3.0 (Box).

Offshore turbine manufacture is often compared to the

production of heavy trucks, and because both industries handle

large heavy components they therefore face high

industrialisation and automation costs as well. A large

difference between truck and offshore turbine manufacture is

in annual output volumes, in the order of 5,000 - 7,000 trucks

versus 300 – 400 turbines. Further complicating these

industrialisation and automation efforts is in ever shorter

lifecycles of turbines, for onshore wind now often with a new

model each 1- 2 years. An additional challenge to further

advance automation in the production processes are customer

demands on turbine specifications, supplemented by new other

skill sets required for future employees.

Virtual assistance tools

Danish turbine supplier Vestas over a decade ago introduced

virtual-reality technology that allowed engineers and service

technicians with special helm and glasses to virtually go inside a

given nacelle. They could then ‘walk’ through, climb on top, open

generator inspection hatches, or for instance check for possible

obstructions when for instance entering the nacelle via the tower

from below. This continuously optimised digital tool offers today

huge potential for checking and in validating new turbine designs

based on and building at the virtual model for further developing

the real hardware.

Finally, turbine and main component suppliers in creating

optimised workflow and product integration at shop floor level,

increasingly deploy an advanced digital software tool to build a

digital twin of a given facility. This is performed prior to actual

plant construction and setting up the assembly process. The tool

enables to virtually predefine all necessary assembly and logistical

steps, then have it all checked in 3D, optimised and validated.

Developing a digital twin can finally be deployed within existing

facilities as well, like in assuring swift effective integration when

introducing a new series product inside these manufacturing

facilities. •

Industrial development: Industry 1.0 - Industry 4.0

Early industrial development commenced with the invention of

steam and hydropower to drive equipment and is described as

Industry 1.0.

Industry 2.0 is synonym with mass production and assembly lines

like Henry Ford made for serial production of the famous

Model-T, and equally key electricity providing new unparalleled

flexibility in power utilisation.

Industry 3.0 is by the introduction and use of Automation,

Computers and (power) Electronics.

Today’s Industry 4.0 industrialisation phase is characterized by

key words Cyber physical systems, The internet of things,

Networks, and Artificial Intelligence (AI).

Q/A with Harold Veldkamp, Director Digitalisation Programme at Topsector Energie

Protecting our power


Sustainable energy production should contribute to the Dutch government’s

ambition to achieve a fully CO2-neutral energy system by 2050. Large-scale wind

energy, particularly at sea, will make a major contribution and large investments

are therefore being made in this area. But with this capital intensification, the

power plants are also becoming more financially attractive to hackers.

Windpowernl spoke with Harold Veldkamp from

Energy Innovation NL (Topsector Energie) about

this topic. Since September 2020, Veldkamp has

been Director of the Digitalisation Programme

within Energy Innovation NL, the driving force behind

innovations that are necessary for the transition to an affordable,

reliable and sustainable energy system.

Digitalisation is a theme that cuts across all Top Consortia for

Knowledge & Innovation (TKI) within Energy Innovation NL.

Together with TKI Wind op Zee, part of Energy Innovation NL,

Veldkamp is investigating the role of digitalisation within the

offshore wind community and what digital innovations are

possible or desirable here. Cyber security is an important subject.

Is cyber security on the agenda of the wind


‘The wind sector is relatively young, certainly in the size and

application as we know it today. For years, the focus has been on

the actual realisation of wind farms; how they could be built and

financed. Issues such as cyber security, as well as circularity and

recycling, have only recently become important. When there were

not yet so many wind turbines, there was also much less a

necessity to focus on this. Now that sustainable decentralised

energy is growing and will continue to increase, cyber security has

become an important factor within the Dutch energy mix. Wind

farms, but also solar parks, are increasing in size, involving much

larger investments. This makes these energy projects increasingly

more interesting for hackers. After all, the effort has become much

more rewarding.

At the moment, new legislation in this field is being prepared on a

European level. The Ministry of Economic Affairs is responsible

for the national translation. The wind sector already falls partly

under the supervision of the Dutch Radiocommunications Agency,

which is the supervisory authority for cyber security for the entire

energy sector. This means that, for the first time, the wind sector

must prepare itself for everything that has to do with cyber

security risks.’

What are the main cyber security risks?

‘Most cyber-attacks can be roughly divided into four categories.

At the top is ransomware. With this type of cyber-attack, the

hacker is not out to destroy the system itself but purely to realise

financial gain - by temporarily blocking access to the system and

only making it accessible again to the owner in exchange for a

large sum of money. For now, the danger comes mainly from

North Korea and some Eastern European countries. Not everyone

is aware of this, but ransomware is the world’s third largest

economy after China and the US. A country like North Korea

runs almost its entire budget on this income. So this is definitely

something to take seriously.

The second form is industrial espionage. Again, no damage is

done to a system. The system is only observed to gain knowledge.

This is mainly done on a nation level and used to influence the

competitive position of a country favourably, for example in the

case of large contracts or if a country is lagging behind in a

particular area of innovation. It should be noted that this is not

only used by traditional enemy nations.

In a third form, damage is actually caused deliberately to an

(energy) system for various reasons. This involves not only direct

financial damage but also production damage. We have recently

seen examples of this in the conflict between Russia and Ukraine.

In a fourth situation a system is hacked in order to manipulate

production figures. An example is manipulation of meteorological

data which is used to predict the algorithms of wind farms. The

ultimate goal is to take advantage of the energy trading market - in

effect, so-called insider trading.’

What are the main risks for wind farm owners?

‘If a hack brings a wind farm to a standstill, this obviously has

financial consequences for the wind farm owner. However, it can

also have a wider impact, especially if the hack brings down several

wind farms. If a large amount of wind production is suddenly

withdrawn and then fed back into the grid, this could cause a

complete blackout in the Netherlands. However, because this is

caused at a high voltage level, it can also effect the grid at

European level. TenneT, the Dutch manager of the high-voltage

grid, has interconnectors with the countries around us. The grid

managers in the Netherlands are very active in the field of cyber

security but they have no influence over the parties that supply the


Are the risks similar for on and offshore wind?

‘The technical risks are comparable; the same applies to solar

parks. But there is an additional risk dimension for offshore wind

as there is no permanent control with human presence. Therefore

you are less likely to realise immediately that something is going

on. As a result, it will take much longer before you can take the

necessary steps.’

Is the wind sector well aware of the risks?

‘As with all new things, this requires time and adaptation.

Unfortunately, cyber security risks can sometimes have a long

incubation period and only become visible later. We notice that

awareness in this area can still be improved significantly. For

example, there are still companies that connect their Operational

Technology (OT) directly to the Internet. An OT system is the

interface to the wind turbine, which allows you to switch a wind

turbine off and on again. We also come across examples where

some systems are still programmed on Windows XP, which has not

been supported for years and therefore entails major security risks.

This is also why Energy Innovation NL is initially focusing on

creating awareness. This applies to the wider energy sector.

For the wind sector, we want to make an assessment tool available

together with TKI Wind op Zee. This tool should help companies

to assess for themselves which cyber security risks they are

running, whether they are properly prepared, and what they need

to take into account. Of course it is not a complete cyber security

assessment, but compare it to a COVID home test. If the result is

not good, you start taking measures.’

How can companies protect themselves?

‘The natural reaction is to prevent being hacked. However,

hacking tactics are constantly evolving. It may be impossible for a

company to completely prevent attacks. The consensus among

cyber security experts is: you don’t have to ask yourself

WHETHER you will be hacked, but WHEN. It will happen one

way or the other.

Be well prepared and make sure you have the basics in order. I

sometimes compare it to a burglary. Once the burglar gets through

the front door, he has immediate access to the whole house. This is

also often the case with companies. You can prevent this by means

of compartmentalisation. Instead of just implementing a large

security wall around your entire system, you should also secure

internal parts seperately. This has two major advantages. First of

all, it will more likely discourage hackers. After all, they need much

more time to get through the various protections. Secondly, you

limit the damage. By compartmentalising, hackers will need much

more time to achieve their goal. While the rest of the company

keeps on running, you can already start taking measures.

What can be done across the wind sector?

Knowledge sharing in this area is sensitive. Those who are hacked

often feel enormous shame and prefer to keep this silent. However,

some sectors did prefer to bundle knowledge from multiple parties

because they found it impossible to keep up with cyber security

knowledge on an individual level. This is where the Information

Sharing and Analysis Centres (ISACs) originated. In the ISACS,

experts from various companies exchange knowledge about these

types of vulnerabilities, with warnings but also solutions for new

vulnerabilities. The National Cyber Security Centre advises the

government in this respect. We also want to set up this kind of

knowledge exchange for the mobility, solar and wind industries.

It is finally up to each company to do something with it or not.’

What about start-ups that provide softwarebased

products and services?

‘The dilemma with innovations is that innovative companies like

to bring their idea to the market as quickly as possible, to make

sure they are first. Here, cyber security may receive less attention.

I would definitely like to give them the “security by design” advice:

make sure you include cyber security in your design process. If you

don’t have time to build it in now, you certainly won’t have time to

correct it later. As a company, ask yourself the question: can you

afford, if your solution proves successful, to be hacked later and

have a bigger problem?’

Do we in the Netherlands have sufficient

knowledge in the field of cyber security?

The Netherlands has a good cyber security knowledge industry.

Do we have enough people? No, absolutely not. That’s why we’re

working with the ten top sectors to develop a broad-based

programme. This is a knowledge development programme for all

levels. We are going to finance all kinds of knowledge projects on

cyber security on the basis of knowledge questions that we are

receiving and are now collecting.

Part of that programme is the human capital agenda. We want to

ensure that we train enough people to do this work. This is not an

easy task. It turns out to be quite difficult to reach these people.

There is also quite a bit of knowledge involved. It’s not just about

having the practical knowledge of hacking, but you also need to

have background knowledge, including system and legal

knowledge. The National Cyber Security Strategy will contribute

to this, just as the major EU projects in the field of cyber security

will contribute to the further development of product cyber

security (minimum requirements such as 2-factor authentication,

patch management etcetera). In addition, important entities in the

vital energy sectors will soon be subject to compulsory legislation.

Fortunately, there are training courses in this area that will also

guarantee knowledge in the future. This happens at all educational

levels. With this broadly supported programme, we are trying to

give an extra impetus to further development in this area as well. •

Fugro’s Blue Snake® technology:

Efficient data collection

for quality cable route


Digitisation contributes to an increase in efficiency in the processing and

interpretation of data, which enables timely and well-informed decision making.

Improving the technology that is used to produce data can, in turn, help make

data available even faster. As the sustainable energy market continues to grow at a

rapid rate, the need for efficient data delivery is critical.

Blue Snake® on the geotechnical vessel Fugro Synergy © Fugro

This is confirmed by Sven Plasman, Principal

Commercial Manager at Fugro, the world’s leading

Geo-data specialist firm that, among other things,

conducts geophysical and geotechnical surveys in

offshore wind farm zones around the world. With the acquired

Geo-data, potential wind farm developers can make intelligent

decisions on the optimal wind farm layout, foundations, cables

and cable route designs for future projects.

The roll-out of offshore wind energy in the coming years is a

key part of global strategies to combat climate change and

support the move towards green energy. Many of these wind

farms will be huge, such as the IJmuiden Ver offshore wind

farm zone which could see up to 6 GW of installed capacity in


The Netherlands Enterprise Agency (RVO) also has a number

of large tenders out for offshore wind areas, with these set to be

awarded in November. Fortunately, Plasman has noted that as

the drive for wind farms increases, clients have become more

flexible and open to new ways of working.

Blue Snake ® : 2 in 1

With the fast roll-out of offshore assets, Fugro began

developing the Blue Snake ® , a geotechnical system which

integrates cone penetration tests (CPT) and vibrocore

sampling, a technique for collecting core samples of the seabed

sub-strata sediments, to enable safe, efficient and high-quality

data acquisition along wind farm cable routes (see Box). The

Blue Snake ® system delivers many benefits.

Improved operation efficiency

The obvious advantage is time saving. With traditional methods,

two different systems are used on board a research vessel for

the CPT and sampling activities. These systems are separate.

Each is lowered onto the seabed – one after the other – and

retracted again on deck. With the Blue Snake ® , these two

operations take place simultaneously using one system,

therefore making the operations more efficient.

‘With the Blue Snake ® , two operations take place

simultaneously, using one system, therefore making the

operations more efficient’

In addition to this, an advanced heave compensation system

ensures that workability is improved. ‘The extent of this

improvement depends on the type of vessel on which the

Blue Snake ® is used,’ Plasman explains. But significant wave

heights of 1.75 or 2 metres are possible for the Blue Snake ® .

This time saving automatically translates into a reduction of

emissions because the vessel is out on the water for a shorter


The Blue Snake ® design also leads to safer work operations due

to less manual handling. Plasman: ‘With the traditional method,

you bring the vibrocorer on board, over an A-frame. This can

involve some movement which needs to be manually corrected.

The vibrocorer needs to be manually coupled and uncoupled,

this makes it a difficult manual handling operation. With the

Blue Snake ® , the vibrocorer is transferred hydraulically in one

go and is immediately fixed. That makes it much safer to work

with for the crew on deck.’

Improved data correlation

When it comes to the data quality itself, there are also major

technical / quality benefit. In the traditional method, the two

activities take place somewhere near each other but never really

at a fixed distance, Plasman explains: ‘With the Blue Snake ® ,

the distance between the two operations is fixed. As a result,

you get much better correlation between data which leads to

better interpretation of the data.’

Faster data processing

Faster operations also mean that the data can be examined

more quickly. The 6-metre long vibrocore samples are cut into

1-metre pieces on deck and placed in refrigerated 20-foot

containers until the vessel enters port again. Depending on the

project, there are two laboratory assistants and an engineer on

board the vessel. They perform a ‘top-bottom’ classification

analysis. These first results are processed and then sent to shore

through Fugro’s cloud-based Geo-data platform.

Plasman: ‘Based on the initial data, we can already determine,

together with the customer, which laboratory tests are required.

By the time the samples arrive at the port and can be shipped

out to the labs, the geotechnical lab team knows which

programme they need to run.’ The data from the geotechnical

survey also goes to the geophysical team who integrates it into

their data interpretation. This is all digitally processed and

interpreted with geographic information systems (GIS).

Fugro has recently opened a new laboratory in Belgium and

made significant investment in their UK and global

geotechnical laboratories. ‘This has resulted in around 50

percent increase in capacity which will significantly reduce

turnaround time of test Geo-data and ensure a rapid response

to the growing demands of the energy sector,’ says Plasman.

Commercial application

The market launch of the Blue Snake ® came at a good time.

Fugro was awarded a tender by RVO to carry out a geophysical

investigation for the IJmuiden Ver (Noord) V and VI wind farm

areas. These areas are part of the larger IJmuiden Ver offshore

wind farm zone, the largest offshore wind farm area in the

Netherlands to date.

Geotechnical soil investigations also had to be carried out at a

number of locations. Working from a third-party vessel, Fugro

deployed its new Blue Snake ® system to conduct 25 co-located

CPTs, thermal cone penetration tests (T-CPT) and high

performance corer (HPC) tests.

The IJmuiden Ver scope provided Fugro the opportunity to use

their new system and confirm the quality of the results. This

first project was followed by a large project in the Danish part

of the North Sea, where Fugro was commissioned by Energinet

to carry out soil investigations at 230 locations along the

proposed export cable route for the planned Danish energy

island. The system will also be used for activities in RWE’s Thor

offshore wind farm in Denmark.

Blue Snake ® is currently the only geotechnical system on the

market that works in this way. ‘How the Blue Snake ® is further

marketed depends entirely on how the market responds,’ says

Wind energy

software protection

Like with most industries, digitisation of the wind energy industry is increasing. Good

examples of software that provide energy production gains or cost savings are already

available on the market. But what if you develop a new software solution? Is

protection possible then? After all, European law does not permit the patenting of

software as such. However, more is possible than you might think. Patenting software can

therefore be very worthwhile.

Plasman. For the efficiency of the system, it is desirable that the

customer requests a CPT and vibrocore sample in the same

place. But sometimes customers want alternate samples, he

explains: ‘That is still possible, but the efficiency and benefit of

better data correlation will be reduced. These are benefits that

clients value, so we’re already seeing an increase in demand for

the system.’

Blue Snake ® deployment

The Blue Snake ® system can be deployed on various vessels.

Preferably, a dedicated vessel is assigned for the Blue Snake ® as

it takes a few days to install the system and requires some

modifications to the vessel.

Continuous improvements throughout the


‘The Blue Snake ® is just one type of system within Fugro’s

geotechnical range of equipment,’ Plasman stresses. The

company is also working on several other technical

developments in this area, particularly in the CPT field.

Plasman: ‘We are continuously looking at how we can give

customers better in situ information. With the standard CPT

we can get to depths of 50 to 55 metres. We are developing

cones that can go deeper and press harder, because the deeper

we go, the better the data will be for our customers. We are also

improving and refining the quality of our seismic CPTs. The

data obtained provides insights into all kinds of soil

characteristics which are important for foundation design.’

Blue Snake ®

With the Blue Snake ® geotechnical system, the CPT is

mounted in a frame and can be pushed into the seabed up

to 6 metres - and even deeper with some adjustments – to

Of course, efficiency gains are not limited to the geotechnical

survey equipment that Fugro provides. On the geophysical

survey side, for example, Fugro’s uncrewed surface vessels

(USVs) are remotely controlled via remote operations centres

(ROCs) across the globe. With real-time data transfer, staff can

analyse and interpret Geo-data without having to mobilise

offshore. The USV’s are also becoming larger: from 12 and 18

metres to 24 metres with greater endurance, station keeping

and payload capacity.

Another focus for Fugro is sustainable operations. Along with

growing its range of USVs, which have up to 95 percent

reduction in fuel consumption when compared to traditional

survey vessels, Fugro is also in the process of converting its

vessels from marine gas oil to methanol and biodiesel.

‘Ultimately, we want Fugro to be completely carbon neutral by

2035. It will take small steps, but the goal is rock-solid,’ says

Plasman. •

acquire soil samples using a fixed sample tube. The

Blue Snake ® can be used in waters from 3 to 100 metres

deep. The system is therefore very suitable for preparations

of the construction of wind farms, submarine cable routes

and pipelines.

‘Due to a legal

provision, the

software must be of

a sufficiently

technical nature in

order to be

protected by a


Software is subject to copyright, providing already limited protection. With a patent broader

and thus better protection is possible. Due to a legal provision, however, the software must be

of a sufficiently technical nature in order to be protected by a patent.

Technical impact

If you are the inventor of a new and innovative physical product for generating wind energy,

then it is clearly a technical solution. With software, that is not always the case. A programme

that processes customer data, sends out invoices, or collects data is usually not categorised as a

technical solution to a technical problem. It can therefore not be protected by a patent.

Nevertheless, under certain conditions a patent can also be obtained for software. One

condition is that the software has a technical effect. For example, an application that adjusts the

position of wind turbine blades in relation to the direction and speed of the wind. Or artificial

intelligence that learns to recognise, via photos, when corrosion is developing on the tower or

other parts. This enables timely maintenance. In other words: a technical solution for a

technical problem, with an effect in the physical world.

Ahead of the competition

The average software innovation in the wind energy industry is therefore patentable. But what

is the advantage? An important advantage is that you offer something that someone else does

not have. In a tendering process, this will give you an advantage over your competitors. Think,

for example, of an application that allows you to carry out maintenance remotely. This is faster

and cheaper for your customer and makes you more interesting as a supplier.


It is not only personal use that makes a patent worthwhile. With the patent, you are in control;

you determine who may use your innovation. You do this, for example, by licensing the

software. This gives you control over the parties that work with your innovation and you also

reap the financial benefits.


Even though many things are possible, applying for a patent on software remains a complex

matter. Research into novelty and a watertight description of the innovation are required. The

novelty and inventive step must be clearly evident. Therefore, always call in an expert when you

are thinking about patenting software applications and, together with a patent attorney, ensure

that the patent will benefit you.

TechBinder’s Smart Vessel Optimizer

Smart & efficient vessel


While the industry has been digitising production processes for decades now, the

maritime sector is still cautiously taking its first steps in this area. A pity, thinks

Bram van den Boom, CEO of Dutch start-up company TechBinder, as the

advantages are enormous and the step is necessary.

The fact that the industry has

such a head start - more than

40 years - has everything to do

with the pressure imposed by

regulations to trace the origin of products,

explains Van den Boom who has a background

in the Food and Pharmaceutical

industries. All data from the production

process therefore had to be recorded in detail

in order to comply with the mandatory


The various assets in a production line

send out signals. Van den Boom: ‘You can

do smart things with these signals. You can

create automatic reports, predict

maintenance, but also optimise your

operations and reduce waste or emissions,

for example. He tells of a project at beer

brewery Carlsberg where the performance

of all production lines worldwide was

collected in one control room. This made it

possible to compare the different

production lines and to implement best

practices for less performing production

lines. Also, the state of the assets and

possible faults could be captured in one

single place.

Van den Boom: ‘This allows for continuous

improvement. When a fault occurs, the

dedicated technician can do his or her job

very specifically, which greatly improves

the uptime (and therefore profitability) of

the production line.’

16 | 02-2022

Industrial machine

Van den Boom came into contact with the

maritime world when he was asked one day

to speak at a conference on how the

experiences of digitalisation in Food and

Pharma could be translated to the

maritime sector.

‘The conclusion of that talk was actually

simple,’ he explains, ‘a vessel is just a

floating machine. A production machine

contains generators, engines, valves, et

cetera - all the things that you also

encounter on an average vessel.’

‘We can map out in

great detail where

optimisations can be

made and how they

contribute to your

business model’

However, there are also major differences.

A factory machine operates in one set

location; in a conditioned space and 24/7

at the same level. A vessel, on the other

hand moves continuously. The conditions

in which vessel assets operate also fluctuate

more. For example, the temperature can

vary continuously on a vessel and vessel

assets have to run at different power levels.

External factors, such as the weather, also

have a much greater impact on vessel assets

than factory assets. But also, who is the

captain? Moreover, the value chain is more

complex within maritime operations.

Otherwise, it is exactly the same units that


Conservative sector

The maritime sector could therefore also

benefit from digitalisation, it appears. After

all, this market is facing a number of

challenges. Vessel assets are becoming

increasingly complex and there is a

growing need for reporting. In addition,

there is continuous pressure to reduce

emissions. In 30 years’ time, every vessel

will have to be climate-neutral. Taking into

account the lifespan of a new vessel, steps

have to be taken quickly to reach that goal.

According to Van den Boom, the fact that

the maritime sector is still slow to take

steps in this area is due to the (more)

complex value chain and because it sticks

to the same working methods. Moreover, it

is a small world in which new players and

start-ups have difficulty getting in. Then

you really need the help of a coach or

initiatives such as the PortXL maritime

accelerator programme, Van den Boom

Optimisation before


According to Van den Boom, optimisation

is the first step before the shipping industry

can transform. Digitalisation is a huge

enabler in this process and ultimately also

ensures that you can sail more efficiently,

run more efficient operations and do more

with fewer people. The latter is actually

where our real story begins, explains

Van den Boom: ‘Asset technologies are

becoming more complex while more and

more people in the field do not have the

knowledge or training to deal with this

complex technology. The generation that is

now entering the market is also much less

loyal to an employer. As a result,

knowledge does not stay within the

company and is not enhanced.’

Digitalisation offers a valuable input here,

thinks Van den Boom. ‘The efficiency of an

organisation is determined by the efficiency

of knowledge transfer within certain

knowledge domains. We are used to

transferring knowledge from one person to

another. Digitalisation ensures that this

knowledge becomes ‘fluid’. You then have

instant access to information and are no

longer dependent on a specialist.’

Smart Vessel Optimizer

A few years ago, together with his former

employer Schneider Electric, Van den

Boom was given the opportunity to run a

pilot with a Dutch shipyard. This

immediately produced a number of

interesting insights for that shipyard. Van

den Boom: ‘We concluded, for instance,

that the operational profile did not match

the technical design of the vessel. This

caused more wear and tear. In the end, we

created a return of investment of one

month for this party.’

This pilot project further aroused his

interest in the maritime world.

Van den Boom founded TechBinder,

together with the former service manager

of the shipyard. The company is supported

by Schneider Electric, among others. The

piece of technology that was developed for

the shipyard was further fine-tuned and is

now marketed under the name Smart

Vessel Optimizer. A vessel is not

fundamentally designed to be digital.

Moreover, every vessel is different ‘under

the bonnet’. A somewhat complex vessel

can already have 300 different systems

integrated on board, all producing their

own data/signals and speaking their own

‘language’. The signals are often lost or

stored in a log file in the system of the asset

itself and are difficult to retrieve. Often,

these log files are only called upon and

analysed after an incident.

Van den Boom: ‘That’s regrettable, because

Smart Vessel Optimizer makes it relatively

easy to retrieve these signals (live) ashore.

‘This way you can always monitor the

condition of your asset and react sooner

based on trending. It is also possible to

perform remote troubleshooting and

instantly solve a failing asset much more

often. This benefits the availability of your

floating machine. A

production machine

engines, valves, et

cetera - all the things

that you also encounter

on an average vessel’

vessel, and the cost of repairs. As a vessel

owner or operations manager, you want to

own the data streams. You can use it for

your own benefit but you can also tune the

whole value chain, such as service

providers, insurers and the shipyard to

what you are doing.’

Faster decision making

‘Because a selection of all available data

points are now brought to shore in a

structured way, you can start making

combinations and sharing insights with

people who can then do their work more

efficiently and faster,’ Van den Boom

explains. ‘He tells of a customer who used

to call all the vessels every morning to ask

what they were doing, what their ETA was,

how much cargo they were taking, etcetera.

‘That is a time-consuming activity for both

the captain and the company. Based on just

a few data points, we were able to present

this information in a live dashboard and

only the salient issues of the day were

highlighted. This brought enormous

efficiency to both operations and also

avoided a lot of miscommunication,’ says

Van den Boom. By only highlighting the

things that stand out, you can create a

much better overview with fewer people.

A good data system also works in such a

way that the more information you put

into it, the smarter it becomes for an

operation. Van den Boom: ‘We can map

out in great detail where optimisations can

be made and how they contribute to your

business model. You can only create that

kind of insight by monitoring in detail and

in a structured way over time.’ Another

advantage of the system is that connections

can be made between assets. He mentions

the example where TechBinder traced the

rootcause of a high energy consumption of

a vessel. It turned out to be a leak in the air

system that caused the compressor motor

to be urged to increase its pressure every

15 minutes.

Cyber security

TechBinder develops purely in a functional

area. They set up the infrastructure, the

data belongs to the customer. The

customer determines who sees what and

who does not. The back-end of the tool is

heavily tested and scalable technology that

is also used by the industry. Van den Boom:

‘For us, it is a strategic consideration to

take that industrial technology, which is

already 40 years old and was designed for

this purpose only. You can’t actually do

that yourself. It also offers advantages in

terms of Cyber Security, then you know as

a small company that you’re in the right

place. All our systems are continuously

monitored and proactive action is taken

when a suspicious situation arises. In

addition, it is only possible to retrieve data,

you can never access a PLC or modify

anything on the vessel.

Progressive shipping


But is the maritime market ready for this

now? Van den Boom: ‘Yes indeed! The way

the maritime market should look at it is

that this technology simply changes the

rules of the game. If you do it right, you

can gain an enormous (competitive)

advantage. It does require a completely

different set of skills and insight within the

organisation. Van den Boom has noticed

that the people on board often get excited

to get started. Many captains want to sail

more sustainably, for example by getting

the best setup between engine power and

pitch, but do not have the proper

information to do so. ‘We use people’s

creativity to look for the optimum. They

are all professionals who want to do their

jobs properly. With this information, they

can also steer more actively in that


Fortunately, there are already more and

more initiatives taken and maritime players

are warming up to digitalisation. ÈTA

Shipping in Leeuwarden is one of them.

They are building up a shipping company

from scratch and have a number of new

ways of looking at things. The company is

going to be set up digitally from the ground

up and will be building modularly. Van den

Boom: ‘We are going to take care of the

complete digitalisation for them. Because

they do not have any vessels yet, we can

Shared experiences

also be involved in the design of the vessels.

ÈTA Shipping focuses on short sea and

large transport. Eventually, they will also

start transporting wind turbine blades.’

Future vision

In principle, TechBinder focuses on

shipyards, shipping companies and OEMs,

the parties that supply components,

although the service providers can also

benefit. In doing so, the start-up has an

ambitious goal: in four years, they want to

have their service implemented on at least

1,000 vessels worldwide. •

Flexible, modular systems

TechBinder has designed the Smart Vessel

Optimizer system in such a way that it can

be gradually expanded. At this moment the

system can talk to 600 different types of

PLCs. These are computers that control

assets. The smallest system consists of a

box of 47 x 54 x 23 centimetres and can

extract 50 measurement values from up to

3 systems. For example, for measuring fuel,

speed and location. It is aimed at retrieving

data for OEMs or on inland vessels. Van

den Boom: ‘With the largest system, you

can extract infinite systems and measured

values. We see these more often

implemented in seagoing vessels and larger

vessels.’ The company Reikon links a small

version to their ballast water treatment

systems. The company will provide remote

support and will take steps in a digital

transformation internally to maintain their

systems more efficiently, but also use it to

automate the Ballast Water Treatment

Book, a report that is still processed

manually. TechBinder also cooperates with

parties such as the Maritime Data

Company. Based on the API provided by

TechBinder, they are now processing very

detailed financial performance of a ship in

a financial graph.

Currently, the quantity of signals allows the

system to still sends all signals to shore via

satellite. ‘Eventually, you also want to

enable intelligence on board to analyse the

assets on site. We are prepared for that,’

adds Van den Boom. •

Benchmark for all

maritime & offshore

compliance requirements

Anyone who wants to work in an offshore wind farm has to make sure they are

complying before even being allowed to go offshore. Organising the certification

status of own, hired or subcontractor staff can be a time consuming activity if not

organised properly, especially on multilevel projects. Terschelling-based

Certscanner found much room for improvement in this area and developed an

automated digital solution for all compliance and certification needs.

Windpowernl spoke to Jens Doeksen, Director of

Marine Coordination Services BV (MCS), based

on the Wadden Sea island Terschelling, and

founder of Certscanner.

Doeksen has been involved in several wind farm projects as a

marine coordinator and later as a supervisor. In almost every

project he worked on, he faced the same challenge in the area of

certification and compliance. He noticed that the collection and

processing of (hired) staff and subcontractor certification was

often inefficiently organised at the various projects. More often

than not, Excel sheets were used to keep track of certification and

compliance and was often performed ad hoc, when required. To

the surprise of Doeksen: ‘You need to comply before you are

allowed to go to an offshore wind farm. Organising this properly

can save a lot of time and money, not only on a current project,

but also on future projects.’

Hence he came up with the idea to develop a tool that would

provide a single point for managing all compliance and certificate

related activities. Doeksen: ‘I wanted to create a solution where all

parties involved on a project are brought together in one single

automated digital platform that would enable efficient, safe, and

optimal project operation.’

At a certain point, he started to involve more people on his

project. First his partner in MCS, Cor van der Velde, later followed

by Heert Schroor. Together they started the actual development of

the digital solution, Certscanner, in 2019. And now it is time to

bring the solution to the market.


The company is focused on multilevel scopes in the maritime,

shipping and offshore industries and provides an efficient SAAS

solution for various (flexible and cross) project & personnel

management for offshore wind farm (OWF) developers, main

contractors (EPCI, T&I, commissioning), subcontractors, and

(offshore) professionals.

The foundation of the multi project level ecosystem is the

digitalisation and verification of professional certification subject

to user desired multilevel trainings matrices - all automated via the

platform itself.

Developers & Contractors

OWF developers, main contractors and subcontractors can costeffective

benefit by having all their own and/or hired staff or

subcontracted personnel on all levels of the assigned project

registered (and transferred to other projects for compliance

checks) in some clicks in the platform in order to maintain

compliance to subsequent OWF employer, main or subcontractor

requirements for offshore or site access.

The platform allows them categorisation of their personnel under

various customised projects & departments (including marine

support vessels) own training matrix.

Certscanner also offers a team management solution for creating

and monitoring their daily planning, while staying up to date in

real time about any changes in the status of the certification of all

(hired) staff or subcontracted personnel on all levels of the

assigned project.


The Certscanner portal for professionals offers these users a

digital wallet for professional certification, a personal work

scheduler and an environment that keeps them up to date about

the projects on which they’ve been assigned to.


The SAAS solution in addition enables all users to source offshore

energy sector (or other) courses within a secured environment and

provides a simple booking management for training institutes.

Training institutes can provide verification for certification they’ve

issued in the past, but also promote new courses and issue new


Future vision

Certscanner is already being integrated in the day to day business

of MCS. And Doeksen has high ambitions: within five years, he

wants Certscanner to be recognised worldwide as the benchmark

for all certification and compliance requirements. He elaborates:

‘See it as the central hub in a project where all parties are brought

together in the same digital environment and where processes can

run optimally, safe and cost-efficient.’ •

AI technology for

optimal offshore wind

farm performance

Data is the key to wind farm optimisation. It is important, however, that wind

farm owners have the right tools to interpret their data properly. Dutch/

Portuguese start-up Jungle AI (Jungle) has developed technology that empowers

these companies to increase production, prevent failures and reduce CO2


© Jungle

Jungle was founded in 2016 by three

young men, two Dutch and one

Portuguese, who met at TU Delft and

spotted the growing gap between the

availability of data on the one hand,

and the ability to interpret data on the

other. As the company name suggests, data

has become one big jungle, which makes it

difficult to see what’s really going on.

‘Data can provide companies with the

opportunity to improve and develop.

However, we still see many professional

organisations with very large portfolios

struggle to interpret large amounts of data

with in-house developed and rudimentary

tools,’ says Pim Breukelman, Chief

Commercial Officer of Jungle.

Data jungle

This is also applicable to wind farms.

Breukelman elaborates: ‘Nowadays, wind

turbines are equipped with hundreds of

sensors. For each sensor, static parameters

are set which signal if there is a deviation

from these parameters. This leads to a

continuous flow of notification and alarms

via the SCADA-system. However, not all

notifications are alarming. This leads to socalled

“alarm fatigue” with operators, with

the result that they don’t take action when

in some cases they should.’

Jungle developed their Artificial

Intelligence (AI) product Canopy which

creates a deep understanding of machine

performance and component health by

detecting impending failures ahead of time

and underperformance issues e.g. related

to curtailment and component

misalignment. This allows customers to

significantly increase the availability, output

and lifetime of their assets. Earlier this year,

Jungle won the public award in the finals of

the Offshore Wind Innovators Award 2021.

Normality modelling

Using historical data from wind turbines,

Jungle is able to identify patterns of normal

operational behaviour under all conceivable

circumstances. By applying Artificial

Intelligence (AI), the normal behaviour of

a wind farm can be learned within weeks.

The actual behaviour is compared to the

normal predictions, providing valuable

insight into component health and turbine


The result is that you now only receive a

notification when a deviation from normal

behaviour occurs, a so called dynamic

alarm. Canopy clearly shows and ranks at

which component the highest deviation or

under performance was found, down to the

level of the sensor(s) that detected the

deviation. At that moment, it can be

determined whether the deviation requires

immediate intervention or whether it is

something that could be taken into account

during planned maintenance. By

identifying the need for intervention early,

you prevent unnecessary downtime at a

later stage. Canopy can be used to detect

component failure at a very early stage, but

also, for example, undesired automatic

power curtailment, icing or yaw

misalignment. This leads to better

performing wind farms that generally

produce 1-2% more energy, thus bringing

down the Levelized Cost of Energy. All of

this is powered by software, no single visit

to the wind farm is needed to get these

instant benefits.

Level playing field

Jungle mainly targets the wind farm owners

and operators. ‘They don’t always have

access to the full picture or don’t have the

tools to put it together,’ says Breukelman.

Canopy enables them to keep a close eye

on the performance of their wind farm and,

where necessary, to exchange information

with the party that performs the

maintenance contract, usually the wind

turbine supplier (OEM), on what steps to

take. ‘This creates a level playing field

between the wind farm operator and the

OEM,’ says Breukelman.

However, Canopy is not only suitable for

wind farms, says Breukelman. Next to

wind farm optimisation, Jungle also works

for solar farm owners and operators and is

also deploying Canopy as a Predictive

Maintenance solution for Service

Operation Vessels for offshore wind farms.

In principle, the software can be applied to

any electromechanical equipment with

sensors, he stresses, as the software is asset

agnostic. Because the same algorithms can

be used and no extra hardware is required,

the software can be applied quickly and is

scalable as well.

Since its foundation, Jungle has onboarded

large and small customers from around the

world in the wind industry and is scaling

up rapidly. Just before this article was

published, Jungle raised five million Euros

in additional funding which will enable the

company to strengthen its global team and

expand its product offering to a growing

number of customers across additional

markets and sectors.•

Autonomous drone

inspections for detecting

structural internal defects

in offshore wind turbines

With wind farms being built and planned further offshore, it brings along

additional costs. This is also the case for the inspection and maintenance

activities taking place once a wind farm becomes operational. Developing

solutions that can be performed remotely will help bring down costs. Dutch

start-up SpectX is working on such a solution.

SpectX is developing an autonomous inspection and asset

management solution for application in offshore wind

farms. The Delft-based start-up, founded last year, was

one of the finalists of the Offshore Wind Innovators

Award 2021.

Akhilesh Goveas, one of the three co-founders of SpectX, tells

more about their solution: ‘Current initiatives are mainly focused

on detecting external damage on wind turbines. However, as is the

case with rotor blades, it is often an internal break which occurs.

It is therefore vital to identify this on time, to prevent total shut

down of a wind turbine. Beside the loss of power generation, and

therefore income, it also requires a lot of time to organise a repair

campaign. It often requires workers to perform repair activities by

rope access, which is not totally without risk, is time-consuming,

and restricted by weather windows.’

Structural internal defects

SpectX is building an aerial radiography system capable of

detecting internal structural defects in real-time through Artificial

Intelligence (AI). Goveas: ‘We have tested several different

equipment and, in the end, we found a battery backed X-ray

system that can be used non-traditionally. It doesn’t need a bulky

system anymore so we tried to base the solution on drones. It now

needs to be automated.’

Inspection is performed by two drones that are stored in a docking

station on site. There are several options being investigated for

placing the docking station, for example on a wind turbine

platform or a future docking station for robots in the wind farm.

The drones can be activated and operated remotely, from the

control room onshore, therefore no physical presence is required

on site. The two drones with onboard LiDAR system asset

mapping work in sync: one functions as a sender and the other as

the receiver of the X-ray spectrum. High accuracy is achieved in

aerial positioning using the RTK-GPS aerial position triangulation

aerial principle.

Predicting maintenance & repair campaigns in


‘The solution can be used for scanning the entire wind turbine

from the splash zone up, with the exception of the nacelle,’ Goveas

says. The data is collected and sent to the control centre after

returning to the docking station. The data is stored on the cloud

for analyses of the data by deep learning and is made visual for the

end user. The data allows for repair campaigns to be predicted and

planned in advance, saving expensive OPEX expenditures on

unplanned repair campaigns.

SpectX is working on developing drones that have a reach of

approximately 10 km radius and have a battery life of around 30

minutes. A full inspection of a wind turbine can take up to 1 or 1.5

hour (based on a 3.5 MW wind turbine). To compare: rope access

inspection can easily take several hours (up to 7), requiring several

technicians. The drones are expected to be able to operate in

weather conditions with wind speeds of up to 10 metres per


Development and pilot testing

The system is still in the Research & Development stage. While the

SpectX-team is working on the software, they have partnered with

Avular, a Dutch innovative robotics company, to develop the

hardware part of the innovation. Tailor-made drones need to be

built to actively suppress vibrations during operations. Existing

drones are merely designed for visual inspection. Goveas explains:

‘This technique had not been tested on composite material wind

turbine structure for critical internal defect detection before. Up

to now, we have performed feasibility tests on a used wind turbine

blade to prove the technology for this specific use case.’

In the meantime, SpectX is taking further steps. From the

Offshore wind innovators final event, a Letter of Intent was

obtained from Eneco to SpectX through Glenn Bijvoets, who was

the juror of the competition. At the end of August this year, a

demonstration of the aerial positioning & synchronization

algorithm for two drones, with accuracy capable of performing

radiography took place.

Goveas: ‘The goal is to perform a test on a nearshore wind turbine

in summer time next year. At the moment, the startup is busy

gathering the remaining of the required nearly 1 M Euro to

complete the system and start the pilot.’ •

Determining the feasibility of drone delivery for offshore energy:

Cargo drones to enhance

offshore logistics

On 18 August, in the presence of some invitees and public, a small cargo drone

took off from Den Helder for a test flight to the isle of Texel and back again. This

first drone flight from the mainland to Texel marks an important milestone in the

development and test phase of the “Long Distance Cargo Drone Network”

project, which investigates the deployment of cargo drones to offshore


The Long Distance Cargo Drone Network

project is an initiative that falls under the

Maritime Drone Initiative (MDI), the

drone cluster of METIP (Maritime

Emerging & Enabling Technologies

Innovation Park) in Den Helder where the

latest and emerging technologies are used

innovatively for maritime, marine and

offshore (energy) applications. With regard

to drones, METIP-MDI looks at how

existing or recently introduced drones can

be applied in certain sectors and for certain

business processes.

As such, the Long Distance Cargo Drone

Delivery project focuses on the

development of cargo drones technology

and its sustainable application for

delivering cargo to offshore installations.

In this drone cluster, METIP collaborates

with main partners AirHub, a Dutch drone

software developer and consultant who

create, among others, ground control apps

and Drone operation centers (DOC) for

drone operations, and DroneQ Robotics,

an Unmanned Robotics Systems Operator

& Integrator based in the Netherlands and

the United Kingdom. The activities range

from in-house development of technology

and optimisation of processes, to

compliance with legislation and


Demand driven project

The project originated about two and a

half years ago from the demand of the

offshore community, when METIP and

DroneQ Robotics signed a cooperation

agreement with Energy Reinvented

Community, a platform initiated in 2013

by Shell, Siemens and TNO with the aim

of stimulating cooperation between players

active in the energy industry. Many

offshore players are affiliated with this

platform. Its Digital working group posed

the question to METIP and DroneQ

Robotics how the entire offshore logistics

chain could be optimised, not only in terms

of technology but also in terms of the use

of data. This included the question on how

to further optimise transport of freight to

offshore installations in a most sustainable

and cost-efficient manner, while

guaranteeing safety at all times.

Integration into the

operational processes

DroneQ Robotics has been a core partner

of METIP for more than 2 years, and is the

central coordination partner for the

project. They operate Vertical Take-Off And

Landing airplane (VTOL) drones, supplied

by the German company Phoenix-Wings

GmbH, and equip them with all the

technology needed for offshore application,

including self-developed cameras. John

Troch, one of the founders and managing

director of the company, explains more: ‘

In this project, we are not so much looking

at how we can simply fly from A to B, but

at how we can optimally use drones in the

operational processes and specifically in the

offshore logistics chain. We integrate them

into the operational processes.’

High-priority, high value


To determine how cargo drones can be

integrated optimally in the operational

processes, the project partners first had to

identify where the demand is within

offshore logistics. DHSS, a logistics service

provider also based in Den Helder, turned

out to become an important partner.

DHSS has been a specialist in transporting

people and cargo to offshore installations

for many years. The company made two

years’ worth of data available for analysis:

what is transported to, from and inside

offshore sites, and where are the

opportunities to transport part of the

freight with drones in addition to

helicopters and vessels?

The analysed data showed that cargo

drones are mainly suitable for high-priority,

high-value goods. These include

documents, spare parts, samples and

medicines. For example, when someone

forgot his or her passport, Troch explains.

Drones could provide a more cost effective

alternative here. Troch emphasises that a

drone, however, is not to become a

replacement for a helicopter, it is an

addition. ‘It is all about cooperation. We

need to look at how we can make the

logistics chain more efficient together,’ he


Social acceptance

Another aspect to look at was human

interaction. What is required, not only from

drone pilots, but also from the people

working with the drone pilots and drones.

Troch: ‘Robots and interaction with robots

will only increase in society. We must learn

to manage the interaction with them. It is a

new technology requiring a cultural

change. This will always be difficult in the

beginning. We need to provide people the

knowledge to work with robots. That is why

we have developed a programme for this.’


For a drone flight to operate smoothly and

safely, more is needed than a drone and

drone pilot. This is where AirHub comes

in. AirHub provided the drone software for

the project which is translated into a digital

operations centre from which you can

practice and plan the flight path and then

view, track and control the drone, and the

surrounding fly zone, in a live environment.

Michiel Froling, Business Development

Manager at AirHub, explains: ‘The flight

path is planned in advance: how are you

going to fly and what possible restrictions

are there in the fly zone? After preparing

the whole flight with AirHub, they use a

flight simulator for practising the flight,

offering the same characteristics as the


Troch: ‘We can simulate changing weather

conditions such as strong wind, gusts, wind

directions and precipitation. We simulate

the whole flight to see if the parameters

meet our desired plan.’

Back in the AirHub software the flight area

is drawn and the flight path is set within it.

26 | 02-2022

02-2022 | 27

Creating a flight path with AirHub © AirHub

Waypoints are determined along the route.

These can be used to change the route or

to go into holding mode when other air

traffic crosses the flight path. Also

characteristics like take off speed, waypoint

altitude, coordinates and holding time can

be entered. Two cameras are attached to

the drone: one at the front for obstacle

detection and one below.

If everything is correct, the live flight can

be planned. Froling: ‘You can choose

whether to send the route to the drone or

to a drone pilot. With the AirHub live

stream you can also create multiple

sessions to follow the flight from the

ground or the drone via the RTMP live

streaming.’ Because of the Secure Data

mode which AirHub developed, it is

possible to automatically block all

unnecessary outgoing data. In this way,

the security risks can be limited and the

PWOne could be used safely that day.

The AirHub software also offers other

supporting services. A “live airspace” shows

the restrictions in the flight area and where

other pilots are flying. An “activity feed”

shows what is happening within the team.

This will provide an operational manager

with a complete overview. In addition,

AirHub takes care of the entire compliance

process, Froling says; ‘In aviation, you have

to log everything, from flight time to all the

checklists you follow. These days, you also

have to keep track of maintenance and

report incidents.’ Prior to the flight,

coordination took place with the Human

Environment and Transport Inspectorate

(ILT – CAA) and military air traffic

control De Kooy, Den Helder and the

necessary approvals were granted.

For that day’s test flight, Phoenix-Wings’

personal cargo drone PWOne was used,

which can carry 1 kilo up to 40 kilometres.

The 15-minute flight was performed

entirely on 4G with a radio connection as


Rules & Regulations

At first sight, the flight path for the test

flight that day looked inefficient. Rather

than flying in a 4 kilometre straight line to

the landing point on Texel, the flight path

was leading around a large sand bank – a

total distance of 15 kilometres.

‘A cargo drone is not

to become a

replacement for a

helicopter, it is an


This has to do with an old decree from

1999, Troch explains. Drones legally fall

under aviation and this decree requires that

motorised traffic cannot fly over the

Wadden Sea below 450 metres. This while

drones legally can only fly up to a height of

120 metres. And that bothers Troch:

‘Drones didn’t exist back then. We believe

that the government should stimulate and

facilitate innovation instead of strictly

enforcing the rules that are currently in


Pilot with Neptune Energy

The primary goal of the test flight was to

test the connectivity systems and the selfdeveloped

camera systems. With this test

flight successfully completed, what are the

next steps? Troch: ‘The intention of the

project is to build it up gradually; starting

with stationary offshore platforms and then

moving to more complex structures.’

In the meantime, the offshore company

Neptune Energy already has agreed to take

part in a pilot as soon as permission has

been granted to fly offshore. For this

purpose, the offshore energy company is

making its production platform L10-A,

located approximately 65 kilometres

northwest of Den Helder, available to test

flights with cargo drones from Den Helder.

The drone that will be used there has a

wingspan of 3.5 metres and can carry 15

kilos over a distance of 150 kilometres.

Deployment at offshore wind


Troch also sees potential for cargo drones

to offshore wind farms. But, he says: ‘It will

still take between two to three years before

we move on to wind turbines. Wind

turbines still offer some technical

limitations. The landing decks, for one, are

too small and the turbulence around the

turbines also plays a role.’ Cargo drones

can, however, potentially already be used to

transport goods to the offshore transformer

stations in wind farms or to the larger

vessels that work on these wind farms.

They are currently talking to several

players. •

Exploring international markets:

Business opportunities in

Poland, Romania, Baltics and


In the Dutch wind energy sector, established corporations as well as individual

investors, are always running after the next “hot project”. Despite this hunger for

investments, the construction of new onshore wind projects in the Netherlands,

especially in the latest years, has faced difficulties for reasons related to the

bottom-up approach of the Regional Energy Strategies and in general the high

population and the limited space that is available for the construction of these





However, investors and service

providers can overcome these

challenges by considering

investment opportunities in

other countries, where wind energy

markets are still in their development stage.

Denisa Kasa, Investment Advisor at Energy

Investment Management, has been

conducting research on the entrepreneurial

and investment opportunities created by

the energy transition in Eastern European

and Balkan countries since September

2021. She published a series of country

specific articles on the Dutch news site

Windenergie-nieuws.nl and chaired table

talks on this topic at this year’s WindDay,

the yearly event for the Dutch wind sector.

Windpowernl collected these country

assessments in this article.



Poland, with approximately 80% of its

energy coming from coal and lignite, offers

vast opportunities for foreign investments

and business opportunities in on and

offshore wind energy projects. The

ambition of the country, inspired by the

Green Deal, is to have 27% of its energy

mix consist of wind energy by 2050,

thereby making wind the most attractive

source of renewable energy in Polish


Poland has signed its first Offshore Wind

Sector Deal in 2021, which reinforces

Poland’s commitment to accelerate its

further development of offshore projects,

while in the meantime, ensuring a

maximum of 60,000 jobs through the

years. The capacity of these offshore wind

projects will amount to 16.9 GW by 2040,

with 5.9 GW of these projects anticipated

to be built by 2030. An auction system will

be used by the government to attribute the

projects to the interested parties, starting

from 2025. However, as of today, Poland

does not have any offshore wind farms and

therefore it is lacking in expertise when it

comes to the development, building and

maintenance of these wind farms.

Nonetheless, the government continuously

pushes for local content to be present

throughout the supply chain involved in

these projects. Due to the above-mentioned

lack of expertise in offshore projects,

domestic suppliers can only account for

20-25% of the supply chain. This offers a

rather attractive opportunity for Dutch

companies experienced in: project

development, engineering, construction

and operation & maintenance of offshore

wind projects. By entering the Polish

market at this stage, Dutch companies

could reap the benefits of having the early

mover’s advantage. At the moment, the

Polish offshore wind market is quite high

on the agenda of several Dutch companies,

with several initiatives, supported by the

Dutch trade organisation and Dutch

Enterprise Agency, being initiated to close

partnerships and ways of sharing


When onshore wind is taken into account,

the situation differs, as the latest intel

shows that the country already has an

approximate installed onshore wind

capacity of 6 GW. Similarly to the

Netherlands, investments in onshore wind

are highly dependent on the underlying

policies, which, in Poland’s case, were

restricted by the “Distance Act” which

stated that wind turbines could only be

located in distances bigger than (at least)

ten times their height from residential

building. For a long time, domestic actors

have lobbied against this regulation,

submitting an amendment draft to the

government in 2021. This July, the

government loosened this act, allowing

wind turbines to be built based on a

modified minimum distance from

residential buildings, respecting the local

zoning plan but not falling behind 500

meters. This ease in Poland’s Distance Act,

will translate into an increase of onshore

wind projects in the country. Best case

scenarios by the Jagiellonian Institute

estimate that a high degree liberalization of

the Distance Act, could bring forth

Onshore Wind projects for 2022-2030

amounting up to 11,1 GW. While

development experience is available in

Poland, there is still place for contribution

by Dutch companies as investor/financier

or as service provider: consulting,

engineering, operation and maintenance

services. •



Romania was accepted in the EU in 2007

and ever since, the renewable energy field

of the country has been developing at a fast

speed. At the time, the country had not yet

directed its efforts towards introducing

new technologies in efforts of emancipating

their energy production ecosystem; rather,

it had put a high importance on the

development of hydropower plants, which

accounted for 25.8% of the consumed

energy. While investments in wind power in

Romania have their genesis in 2004, major

developments did not occur until 2008.

At that time, new legislations presented

electricity producers with the opportunity

of being granted Green Certificates for

producing energy from renewable

resources. As a matter of fact, according to

one of our interviewees, Varinia

Radu,partner at CMS Romania, this first

wave of investments (2008-2016) increased


Romania’s wind energy-producing

capacities by more than 3 GW. One can

derive from this that the wind energy sector

in Romania is rather similar to the Dutch

one when it comes to its dependability on

the support schemes and subsidies that the

government establishes. According to Wind

Europe, the installed wind energy capacity

in Romania remained the same, at 3.03

GW, between 2016 and 2020. Regardless

of these facts, now Romania is once again

preparing itself for a new wave of

investments in wind energy projects as

companies and organizations across the

country are anticipating new support

schemes that include enhanced policies

regarding Power Purchase Agreements

(PPAs) and Contract for Difference


A representative of the Romanian Wind

Energy Association (RWEA), Kees

Stiggelbout, told us that the sentiments for

future investments in the wind energy

30 | 02-2022

02-2022 | 31

sector in Romania in the upcoming years

are rather positive. He mentioned that

there are interesting small and middle size

onshore projects planned to be developed

and built in Romania in the near future.

Estimations place the cumulative size of

some onshore wind developments to 1.5

GW, plans which are in line with the

country’s aspirations to increase the energy

mix share of renewable energy to 35% by

2030 (currently 12.4% of Romania’s

energy comes from wind). Interestingly

enough, the World Bank has estimated that

in addition to the attractiveness of onshore

wind projects, Romania has an offshore

potential of roughly 76 GW. However, thus

far there have been no investments in

incorporating wind turbines in the

Romanian territory of the Black Sea.

One of the first investors in this new

segment, is Hidroelectrica, a major

Romanian power producer which is now

diversifying its investments to not only

include hydropower, but also wind energy

projects. The company has pledged to build

an offshore wind farm with a capacity of

300-500 MW in the Black Sea by 2026.

Nonetheless, due to the ongoing conflict

between Russia and Ukraine, developments

in the Romanian territory of the Black Sea

might be put in hold or postponed.

The new investments that will be made to

comply with the Green Deal, will not be

exclusive to wind farm developments, but

rather, will extend to investments in the

grid and conventional capacities. In

addition, as the cost of labor in Western

Europe is surging, it can be beneficial for

Dutch manufacturers of various

components for wind energy projects to

relocate their manufacturing centres to

Eastern European countries.

Dutch wind energy companies ought to be

alert for support schemes or amendments

of law that the Romanian government

might introduce in the future, as these

represent an opportunity for sales of such

equipment to the country. Netherlandsbased

companies working on consultancy

projects, in the upcoming years can hop on

the opportunity that the introduction of

offshore wind turbines in Romania for their

line of business. In addition, solutions for

energy storage would also be welcome in

Romania as the southern region of the

country – where most wind farms are

located – is currently experiencing an over

saturation of the grid as nuclear reactors,

coal-fired power plants and also wind and

solar farm are concentrated in this part of

the country. •



Governmental policies, permitting

procedures, environmental regulations,

supply chains and availability of work-force

in the wind energy sector is known to be

highly volatile when moving from one

country to the next.

However, as new deals are endorsed by the

European Union, the development of new

projects is no longer a “one-man job” that

can be performed by solely relying in local

expertise. For instance, the ‘Baltic Sea

Offshore Wind Declaration’ got Denmark,

Germany, Estonia, Latvia, Lithuania,

Poland, Finland, Sweden to agree on

increasing their combined efforts in

developing offshore wind farms, as this

maritime region has an untapped potential

of 93 GW. This declaration requests its

participants to “cooperate on identifying

potential joint and hybrid projects across

the Baltic Sea and fostering their

development among the countries

involved”. Following this official

proclamation, a first collaboration in the

offshore wind sector was announced by

Estonia and Latvia, who have agreed on

the joint development of a 1 GW offshore

wind farm. Both countries have attributed

space to this project in their updated

maritime spatial plans and intend to hold a

joint auction in 2026 while commissioning

the wind farm by 2030. Between the two

countries, Estonia is more familiar with the

wind sector as it currently operates onshore

wind farms, the capacity of which amounts

to 312 MW. Its government has expressed

that wind energy will be one of the main

bearers of renewable energy in the country.

Additional plans are currently being laid

down by the Estonian government.

The government has postulated that in its

new maritime spatial plan, 1700 square

kilometers will be allocated to offshore

wind farms (the capacity of which can

amount to 7 GW). On the other hand, the

Latvian government has been more

reluctant to increase its wind capacities.

Apart from the shared offshore wind farm

with Estonia, it has allocated no budget or

EU funds to other on/offshore projects that

would be beneficial for the country.

Finally, Lithuania is similar to its

neighbours as it pertains to ambitions in

creating new offshore wind farms. Its

government has developed the “National

Energy and Climate Action Plan of the

Republic of Lithuania for 2021-2030“

which predicts the building of 700 MW

installed offshore wind capacity.. In

addition, estimations for onshore wind

development in Lithuania by Wind Europe

predict a potential increase of capacity of

approximately 1 GW.

Taking into account the different levels of

expertise available in on/offshore wind

developments in Estonia, Latvia and

Lithuania, there are a lot of opportunities

for Dutch companies to get involved in the

above-mentioned energy transition plans.

For instance, Dutch consultancies can

contribute by developing impact

assessments, technological project designs,

aiding in documents submitted for

permitting, and most importantly, conduct


Other attractive opportunities lie in its

developed logistic capabilities, which have

been inherited by the oil and gas

companies. As new offshore projects are

developed in the Baltics, European supply

chains ought to be engaged. Dutch logistics

and installation companies can take the

lead here due not only to their experience

in the Dutch markets, but also because of

their already-established links with the

Baltic Region. •



Denisa Kasa at WindDays 2022

Old energy systems in Eastern Europe are

being abandoned as the European energy

transition goals foster new developments in

the sector, and Bulgaria is no stranger to

these developments. Having joined the EU

in 2007, Bulgaria opted to increase the

share of renewable energy in its energy mix

to more than 11% by 2010. Following this

agreement, and establishing the Renewable

and Alternative Energy Sources and

Biofuels Act, the country started operating

its first onshore wind farms in 2008. Since

then, the capacity of wind energy in

Bulgaria has seen a steady increase

throughout the years, amounting to

approximately 700MW in 2021.

Furthermore, the country’s plans to deploy

wind energy have not stopped at that. The

Bulgarian government has executed the

Bulgarian Energy Strategy for 2020-2030,

which prioritizes the acceleration of efforts

to increase renewable energy deployment

even further for the upcoming years. The

minister of energy has made public plans

that stipulate the doubling of wind energy

capacity by 2030 in efforts to meet the

goals established by the Green Deal.

When offshore wind projects are

concerned, enthusiasts will have to wait for

developments to kick off. Bulgaria

possesses a share of the Black Sea but due

to uncertainties resulting from the ongoing

conflict between Russia and Ukraine, the

development time for projects in this area

has increased. Regardless, the potential for

developments in Bulgaria’s maritime

territory has been estimated at 116 GW,

thereby inspiring a desire for the

introduction of this segment of the sector

in the country.

In a piece by CSD (Center for the Study of

Democracy) named “Wind Power

Generation, Assessment of the Black Sea

Offshore Potential”, researchers have

further elaborated on the potential of

offshore wind in Bulgaria. They estimate

that of the 116 GW of potential, 26 GW

can be realized with mature bottom-fix

technology whilst also depicting the

Shabla/Romanian maritime border, Varna,

Obzor and the Turkish maritime border as

the most attractive areas to place floating

offshore projects.

Similarly to the input that the Dutch can

give with the previously discussed

economies (Poland, Romania, Estonia,

Lithuania, and Latvia), in Bulgaria there is

still place for contribution by Dutch

companies as investor/financier or as

service provider: consulting, engineering,

operation and maintenance services., As

well as with offering assistance in the

supply chains that will be formed,

especially when the offshore wind sector

comes is inaugurated. •

Wind Farm in Focus

Irene Vorrink Wind Farm


This spring, the iconic Irene Vorrink wind farm in the IJsselmeer was dismantled.

It was time for this wind farm by Vattenfall, dating from 1997, to make way for

new wind turbines as part of the larger Windplanblauw project. The Dutch

company Iver was responsible for dismantling the 28 Nordtank wind turbines

that for years dominated the view along the A7 near Ketelbrug.

Iver only recently announced the new name following the

merger between F&B Group from Franeker and Certion

from Lelystad. In the meantime Mocotech has also been

added. By joining forces, these companies want to present

themselves as an all-round European ISP (Independent Service

Provider) that can supply the entire spectrum to the wind sector.

Not just decommissioning services but the complete O&M during

the cycle of a wind turbine.

Offshore ambitions

Although most of the activities are still taking place on land, Iver

certainly keeps an eye on the enormous growth for wind at sea.

Jesse Cuperus, manager sales and operations at Iver, explains that

the Irene Vorrink Wind Farm was an interesting pilot project in this

respect, acting as a stepping stone to the dismantling of offshore

wind turbines. Together with Pieter Thys Faber, Project Manager

at Iver, they tell Windpowernl more about this project.

The turbines of the old wind farm had their ‘roots’ in the

IJsselmeer lake. Although the wind turbines were only located 40

metres from the dike, accessible via a footbridge, the dike’s

maximum axle load did not allow for the transportation of the

heavy components or the installation of cranes. Therefore the only

solution was to dismantle the wind turbines from the water.

‘That made it a unique project,’ Cuperus explains, ‘because it has

common ground with both onshore and offshore projects.

However, we did have to take into account specific offshore

procedures and regulations. In addition, the turbines were installed

on monopile foundations, as with most offshore projects.’

Iver was not entirely in the dark with the Irene Vorrink project.

Cuperus continues: ‘Last year, as part of the Delft Offshore

Turbine project, we assisted in the installation and dismantling of a

test turbine at the Princess Amalia Wind Farm.’

They won the Irene Vorrink decommissioning project after

participating in a tender issued by Vattenfall. The scope of activities

was all-encompassing; from procurement to the foundations, as

well as the subsequent disposal of the components.

As sustainable as possible

The 600 kW Nordtank wind turbines could not be given a second

life elsewhere. The wind farm already had its service life extended

once, and an investigation by Vattenfall had shown that the wind

turbines had now really reached the end of their service life.

However, Vattenfall did want the removal to take place as

sustainably as possible. Iver wrote a sustainability plan for this.

Cuperus: ‘We removed all components from the water in order to

keep the transport lines as short as possible. The machines also ran

on blue diesel. With regard to recycling, we have removed

components that are still usable as spare parts.’ Iver has a large

storage facility in Franeker and Lelystad for this purpose. Faber

adds: ‘People sometimes think we are just demolishing. No, we

dismantle and look for re-use and high-quality recycling.’

Multi-phased dismantling

The project was divided into several phases. The wind turbines and

part of the foundations were removed first, followed by the

remaining parts of the monopile foundations. In a parallel phase,

the cables were removed.

The first phase started on 4 April. A main pontoon was used to

remove the wind turbines and part of the monopile foundations.

This platform of 24 by 55 metres consisted of two connected

smaller pontoons on which a 350-tonne Kobelco main crane and

a 130-tonne Hitachi auxiliary crane were installed. A Multicat was

positioned next to the work platform to manoeuvre the pontoons

during the work.

The Nordtank turbines had a rotor diameter of 43 metres. The

rotor was removed in one go with the main crane and placed on

the platform. With the small crane, the three blades were then

removed and placed on the adjacent Wagenborg auxiliary pontoon

(55 x 11 metres). The components of one entire wind turbine

(nacelle, three blades, three mast sections), the footbridge between

the wind turbine and the dike, and a piece of monopile were

eventually placed on this auxiliary pontoon. These were then

transported to the port of Kampen, a journey of one and a half to

two hours. Two pontoons were used to keep the momentum going.

And while the components were being prepared for transport, a

team was already on its way to the next wind turbine to make


In total, 11 people were working on the water every day. Engineers

from Iver, two seamen from Wagenborg who secured the cargo on

the auxiliary pontoons, the engineers on the cranes, a skipper on

the tugboat and one on the Multicat, and finally a specialist cutter.

The latter cut the monopile. Cuperus: ‘We would have preferred to

remove the entire monopile foundation, but the specifications stated

that they had to be cut two metres below the bottom level of the

IJsselmeer.’ Faber adds: ‘This has to do with the stability function

of the dike. The Water Authority was also concerned about potential

rising seepage water due to leakage.

In the first phase of the project, the monopiles that still protruded

about 150 cm above the water surface were cut with a cutting torch

to 80 cm above the water surface. With a diameter of 3.5 metres

and an edge thickness of 3.5 cm, this process took an average of 45

minutes. The last wind turbine was removed in May. This first phase

proceeded to Iver’s complete satisfaction and without any delays.

Faber: ‘We had a lot of wind in the first week, which meant that we

could only dismantle three wind turbines. After that, we removed an

average of five wind turbines per week. The weather conditions were

great. In the end, we finished ahead of schedule.’

Processing materials

The components were transported over water to Kampen and

immediately sorted and processed on arrival. The cables and

control boxes were removed and the metals separated. The bare

steel towers and hub remained and were immediately scrapped at

the company Hoeben in Kampen. The nacelle and control boxes

were kept. Cuperus explains: ‘This is because we think there is still

a market for spare and overhaul parts and that demand will remain

for some time. Energy prices are high so now it’s attractive to keep

wind turbines that qualify for an extended lifespan operating


The blades went to Vattenfall as agreed. Cuperus: ‘We ourselves

also offered to process these blades sustainably. Via Germany, where

these glass fibre reinforced plastics are processed as an energy

substitute and the residue as a building material for cement. We also

used this recycling method in an earlier project with the blades of

the Landtong Wind Farm. This seems to be the only method

available on a large scale at the moment.’ However, he understands

that Vattenfall wants to go a step further and challenge the market

for better applications where rotor blades can be recycled to a

higher standard. Iver was therefore only responsible for cutting the

blades into small pieces (pre-treatment) so that they could be

transported more efficiently and with fewer emissions.

Removal of monopiles

The removal of the remaining monopile sections was somewhat

exciting for both men. After all, the piles were still some 21 metres

into the ground and had to be cut off at 2 metres below the bottom

of the IJsselmeer. Cuperus: ‘We had obviously never done that on

land before. The question was therefore, how could we efficiently

cut the steel tubular piles at this depth?’

In the end, the decision was made to cut the piles from the inside.

Faber explains the process. The combined pontoon was split for this

purpose: the one with the large crane was removed, while the other

remained behind with the small crane. The piles were then dredged

to 2.5 metres below ground level. Cuperus: ‘It was important that

this work was carried out meticulously without clay adhering to the

inside of the pile. This was to prevent the cutting tool’s cutting

heads from getting stuck during the firing process.’

After the dredging of all monopiles was completed, the cutting of

the piles was started. Iver used the offshore cutting tool of TMS

from Werkendam. A winch was used to bring the tool to the right

depth, after which the lifting frame of the tool was fixed to the pile

with clamping blocks. The tool has two cutting heads and a scraper

to clean the surface to be cut. Both cutting heads rotate 185 degrees

and can thus cut the entire diameter of the pile. Underwater

cameras monitored the quality of the burn-off. The entire cutting

process was controlled and monitored from a control unit on deck

in a container. After cutting the monopile, it was lifted out of the

water with the cutting tool’s lifting frame. The monopiles were then

transported in two batches on a pontoon to Kampen. The removal

of the monopiles took only 2 weeks in total.

After removing the monopiles, the IJsselmeer lakebed was fully

restored by filling and dumping sediment. A sonar survey was

conducted to check whether the bed had been properly restored.

Repair work also had to be carried out on the dike itself. A support

remained when removing the footbridge at each wind turbine.

These had to be removed and the dike was then repaired with

basalt blocks, set by an experienced company.

Extensive preparation

A wind turbine dismantling project is sometimes underestimated.

The complexity increases. In reality the work is similar to the

construction process but in reverse. Not everyone realises that it

involves a considerable preliminary process, says Cuperus. That was

certainly the case with the dismantling of the Irene Vorrink Wind

Farm, as it is part of the larger repowering project Windplanblauw

and has a complex maritime character.

For example, Iver’s activities took place in an area where regular

shipping and various other parties and contractors were also

working, including Ballast Nedam who were preparing the

construction of the foundations for the new wind farm further out

in the IJsselmeerand also the fishermen using fishing pots. This

involved a lot more coordination and fine-tuning, with the Marine

Coordinator of Windplanplan having to be informed on a daily


Necessary permits and notifications were also required for this

specific location. For the dismantling activities, Iver applied for a

permit from both the Zuiderzeeland Water Authority and the

municipality. As the competent authority, the Water Authority is not

only responsible for the dike but also for the first few metres in the

water. Rijkswaterstaat is also closely involved in this process because

of the use of the IJsselmeer. Such a permit process with a complex

project requires the necessary preparations, coordination and a long

lead time.

Iver has therefore drawn up an extensive project plan for this

project. Both focused on the execution method as well as the safety

measures. In addition, an ecological work protocol was drawn up

describing management methods to prevent, for example, birds

from breeding in the work area. Iver mowed strips of grass on the

dike to prevent this. The work area was checked weekly by an expert

for breeding birds and the presence of nests.

‘We took advise on the height at which to cut the piles so that a

cormorant could still escape at any time’, adds Faber.

Cuperus: ‘When you map out the preliminary process well and

make good mutual agreements, the work can proceed smoothly and

according to plan. We started on 4 April and our work proceeded

without incident or any need for intervention by the authorities or

the client.’

End of era

For Iver, the Irene Vorrink project is now complete and delivered,

although the company will continue to dismantle more wind

turbines in the region for Windplanblauw in the coming years. The

men look back on the project with pride. Never before has Iver

dismantled a wind farm with 28 wind turbines in such a complex

environment. For a number of mechanics, however, this has been

an extra special project, says Faber: ‘As a company, we have been

involved in this wind farm for years: from construction, to carrying

out maintenance for years, to dismantling.’ Cuperus: ‘A mechanic

from Iver was involved in the installation of the wind turbines in

1995 and still has photos of it. Now 27 years later (still working as a

mechanic for Iver), he and the Iver team were commissioned to

dismantle the wind turbines, for him the circle is complete.’

Anyone driving by now sees only a dike, like many other dikes in

the Netherlands. But that is only temporary. If you pay close

attention, you will see the activities that are taking place for the new

wind farm to be constructed in the IJsselmeer. Admittedly, this

wind farm will be located further out in the water from the dike,

but the new wind turbines will still be visible from the A6. •

Ode to (almost) lost

Dutch glory

Anyone driving through the Dutch provinces of Noord-Holland and Flevoland can

hardly avoid the many tall wind turbines rising on the horizon. Not that long ago,

these predominantly flat landscapes still housed small kilowatt-sized wind turbines

scattered all over the area. With the trend towards concentrated, large-scale,

megawatt wind farms, these small, sometimes first-generation, wind turbines are

rapidly disappearing or have already disappeared.

Such is the case with the wind turbines of the Dutch brand

NedWind. The last examples of this brand, 17 in total,

can still be seen in all their glory along the Eemmeerdijk

in Flevoland. Special two-bladed, 1 MW units from 1998

with towers in all the colours of the rainbow. But if you want to see

them, you will have to be quick. These wind turbines are also on

the list to be removed.

Windpowernl spoke to Enrico Bakker who collects everything

relating to the history of Polenko/NedWind. And his collection is

pretty impressive. Bakker himself has long since lost track of

exactly how many collector’s items he has, but that they pass well

over several thousand is certain.

Bakker came into contact with the wind turbine brand by chance

when he started working as a maintenance engineer at Vestas in

Rheden in 2005. What he didn’t know at the time was that Vestas

had just acquired the Danish company NEG Micon. NEG Micon,

in turn, had previously taken over NedWind. It was with these

turbines that Bakker initially worked. This is also when his interest

was first aroused.

No simple task

However, collecting NedWind information and material proved to

be no easy task. Bakker: ‘When I started, I had the illusion that I

could find everything on the internet. But a Google search ended

up with next to nothing.’ And that’s quite remarkable, admits

Bakker. For between 1990 and 1998 NedWind was a very wellknown,

purely Dutch wind turbine manufacturer that sold its

products worldwide (see box). NedWind built wind turbines from

250 kW up to the very first 1 MW modular, three-bladed wind

turbine. The latter was in fact the forerunner of everything you see

nowadays, Bakker emphasises: ‘You had the nacelle, built the

gearbox into it, fitted the cover, then the hub, and finally the

blades. In the end, only one prototype was ever built. It stood on

the Zuidwal near Rotterdam.’ That is what particularly attracted

Bakker to the brand, that it was 100% Dutch. Nowadays, many

wind turbines have been taken over by the big ‘giants’ and are

increasingly similar in shape.

Through his work, Bakker eventually came into contact with

Hennie Veldhuizen, who had once started at Polenko, a

predecessor of NedWind, and had experienced the whole cycle of

takeovers. He turned out to be a big NedWind fan and even

wanted to write a book about it. And that’s how Bakker became

really enthusiastic.

Gathering information was going to be a job in itself. Fortunately,

he was able to make a start with the information and material

Veldhuizen was willing to share with him. In the first instance,

Bakker tried to contact as many former NedWind employees as

possible by telephone, but that proved to be a difficult task. Via the

internet proved to be no easy task either. Bakker: ‘Many former

employees of Polenko or NedWind are now of advanced age. Often

they have little or no experience with the internet or whatsapp.’

So he searched for addresses and decided to make contact via a

handwritten letter of two A4 sheets and a photo of his Polenko/

NedWind collection.

This proved to work better. Bakker: ‘It takes a lot of patience.

These people are like guardians of a treasure. They have very good

memories of these companies and don’t just give anything away.

Sometimes it takes months before I have their trust. Finally, I am

asked to come over for a cup of coffee.’ Each of these visits is

special, says Bakker: ‘You can tell that there is a bit of emotion

involved with these former employees. They all seemed proud of

that period in their lives. These men and women really do have

very beautiful stories to tell.’

A museum full of mementos

He was also surprised by the amount of materials they still kept at

home. In the end, the will to share proved great. The mementos

Bakker took home varied from thousands of photos and slides of

all types of turbines and of how a farm or turbine was constructed,

to advertising brochures and leaflets showing prototypes that did

not make it. They didn’t have many real gadgets back then,

although he does have a number of unique Polenko and NedWind

pens and folders and a large Newinco flag, he says.

But he does not only owe his collection to former employees. A

while after Vestas acquired NEG Micon, the company wanted to

get rid of NedWind. This put an end to the existence of the

production of NedWind wind turbines. Another company then

took over the maintenance of the operating wind turbines for a

long time. With the removal of the wind turbines later on, that

company also ceased to exist. Bakker managed to take over a lot of

material from that company.

So, what does he ultimately want to do with all this material?

Bakker: ‘Ideally I would love to start a museum. But will there be

anyone visiting? My ultimate goal now is to publish a book with

information, images and stories - to let everyone know: Hey, this

was Polenko/NedWind and we were pretty big!’ Finally, with so

much material, do you still miss anything to add to your collection?

He didn’t have to think long about the answer: ‘I’m looking for


Polenko/NedWind history

To really understand the history of NedWind you have to

go further back in time. It all started in 1976 with the

wind turbine manufacturer Polenko from Rhenen, which

supplied wind turbines with steel blades in the 30 kW

range. There is only one (non-working) example of this in

the Netherlands, high up in the north of Friesland, dating

from 1981. In the end, it never really worked properly.

Bakker recently spoke to someone who made the lattice

mast for it. There are, however, still a few of this type left

in the United States.

Polenko was eventually taken over by TCR, then

Newinco, Hollandia BV, before becoming NedWind.

Under Newinco, they made one of the most popular

wind turbines, says Bakker. They were found in

Herbaijum, between Harlingen and Franeker, and near


During its existence NedWind has brought various wind

turbine models onto the market: including the NedWind

25, 30, 40, 50 and the Pantheon (NedWind 60). Only

one of the latter was built, this one stood on the south

bank near Rotterdam. Almost all wind turbines had two

blades. The NedWind 25s were mainly located around

Amsterdam. The company had four 500 kW red and

white versions of the NedWind 40 installed in Lelypark

Wind Farm in the IJsselmeer near Medemblik. At a

certain moment one blade broke off from one of the

turbines. It was then decided to dismantle all four

turbines. The turbines had been in operation for about

25 years. Bakker: ‘In Noord-Holland there were also a

number of NedWind 35s with something unusual about

them,’ explains Bakker. ‘One half had polyester blades

with a round connection and the other half had a square

connection. This turned out to be a gentleman’s


The NedWind 40 stood throughout the Netherlands.

They are now only found in Greece, India and China, says

Bakker. The most popular of the series were in Palm

Springs, in the United States. However, these were

removed two years ago. Bakker: ‘With this turbine

model, the nacelle, hub and blades were lifted together

and in one go. In 1998, the company fell into the hands

of the Danish company NEG Micon and a piece of pure

Dutch glory came to an end. •
