Wind Service Offshore
We can’t conquer the elements
But we can outthink them
We make maintenance a routine, not an adventure
Turning unpredictability
into output
Massive waves. Racing tides. Early nightfall. Hail, lightning,
blizzards and ice. All realities that Siemens Offshore
Technicians regularly take in their stride.
Siemens is relentlessly focused on driving down the cost
of wind energy. As a company, we strive to help your
wind turbines produce electrical energy in a wide range
of conditions.
By offering a wide variety of modernization and upgrade
options, we can retrofit turbines to increase their daily
output and reduce maintenance requirements. We have
also put decades of brainpower into helping your offshore
installation deliver in tough conditions. And no less
brainpower into maintaining our service capability to do
the same.
Not through encouraging heroics. Far from it. Our remote
diagnostics are dedicated to identifying and when possible
resolving issues remotely. Our rigorous technician training
stresses the importance of extensive onshore preparation
and planning.
When offshore maintenance is required, a broad variety
of service craft, both floating and airborne, provides safe
access to your offshore installation. Some of our latest
nacelles feature spacious work benches in which technicians
can work, regardless of the elements.
We recognize that the hazards that we are exposed to may
increase as we go further offshore. That’s why our technicians
are rigorously trained to recognize and deal with an array of
challenges – so that, as far as possible, maintenance is a
routine, not an adventure.

Over 20 years of offshore experience
We installed the world’s first offshore wind farm in
Vindeby, Denmark, in 1991 – and it is still running today.
Since then we have gone on to install and service half
of the world’s offshore wind turbines. As our turbines
grow larger and are placed further from land, our service
offering has evolved accordingly.
Today, we lead in the development of new and better
ways to reduce downtime and achieve high levels of
energy production. Looking ahead, we are focused on
maintaining this leadership through continual innovation.
For a service provider well suited to helping you meet
your goals, look no further.
The reassurance of a strong
service partner
When service contracts can last the best part of your wind
turbine’s lifetime, it’s a given that you need a partner
with staying power. Founded over 160 years ago, and
with 360,000 global employees – of whom over 15,000
are employed by Siemens Energy Service – Siemens is
an excellent choice.
Today, our offshore service headquarters in Denmark is
a hub for regional service centers in the USA, Singapore,
Germany and the UK. And with Siemens now
represented in 190 countries, we can quickly establish
a service capability and supply chain close to many
new installations.
The sheer scale of our offshore operations leads to a
more efficient service operation in terms of knowledge
sharing, vessel availability and training.
The world’s leading training centers
With enormously experienced technicians available
as instructors, our training courses are world-class.
Training centers in Brande (Denmark), Bremen (Germany),
Newcastle (UK) and Houston (USA) provide training
excellence in safety planning, technical skills and
survival at sea.
New developments in turbine and nacelle design are
fed directly into our training. We also keep a record of
technicians´ individual competencies so that suitably
specialized teams can be made available for specific
tasks. Our training allows our technicians to react to
situations in an efficient, and above all safe, way.
Increasing availability
with proactive planning
Offshore work could be unavoidably costly if not for
Siemens Remote Diagnostic Services. Through remote
monitoring and intelligent planning, we can turn unplanned
repair work into planned preventive maintenance – reducing
time spent offshore and maintaining high energy output.
•24/7 remote monitoring of turbines, SCADA and park
control allow for improved remote and fast fix rates,
and efficient dispatching of service technicians onsite,
resulting in increased production
•A variety of diagnostic support services is focused on
improving the troubleshooting and support of hardware
The right craft for every task
Based on historic and simulated weather data, we tailor
the logistical set-up for each individual wind farm, taking
into account its location, distance from shore, water
depth, tidal variation, weather complexity, wave height,
and models and numbers of turbine.
The access craft we utilize can reduce turbine downtime
through accelerated response times, better and safer transfer
and access, and extended service weather windows.
Crew Transfer Vessel (CTV)
Service Operation Vessel (SOV)
Standalone units for far shore wind farms, the SOVs utilize
self-stabilizing platforms with gangways for direct access
to the wind turbines which reduces the risks and loads
involved with boat landing and ladders.
With accommodation for technicians as well as appropriate
storage facilities for all common used spare parts, the SOVs
are designed for long-term duty at the offshore wind farm.

The impressive track record of remote monitoring and
vibration diagnostics, combined with our comprehensive
support services, makes Siemens a trustworthy and reliable
service provider.
•Advanced vibration diagnostics in many cases enable us
to predict potential damage to essential components,
thereby potentially preventing major breakdowns and
delivering substantial savings.
Cost-efficient and safe, CTVs are mostly used to transfer
technicians and components to near shore wind farms.
For more remote ‘far shore’ wind farms, the CTVs are also
utilized for transfers in combination with either a Service
Operation Vessel or offshore accommodation platform.
Our service technician training is focused
on reducing risks. Not taking them.
and software components (turbine, SCADA and park
control), with the objective of leading to greater reliability
and performance of wind farm control and grid support.
Providing stable and comfortable accommodation
facilities for a large group of technicians, as well as ample
Specialist service vessels: saving time, helping enhance your returns
storage facilities, the accommodation platform is an ideal
long term reactive maintenance facility for large and far
shore wind farms.
Helicopter
With its speed and flexibility, a helicopter enables fastresponse deployment of technicians and smaller components,
even to far shore wind farms. Technicians are hoisted directly
down to the nacelle’s heli hoist platform, with immediate
access to the nacelle itself.
Looking ahead
With installations being planned further and further offshore
– especially off the UK and Germany – Siemens is already
planning new concepts to service the wind farms of the future.

Innovative and responsive
Industrialization
The ever-increasing scale of the wind industry has led
to the inevitable industrialization of its service sector.
Larger wind parks require access to service craft and
supply chains. Larger turbines require bigger technician
teams that rely on standardized planning and
procedures honed by years of training and experience.
It’s a situation to which a global company like Siemens
is extremely well suited.
Among the major benefits of industrialization are the
economies of scale that result. As a provider of service
solutions to many of the world’s offshore wind farms,
Siemens can help you explore the option of sharing service
resources with neighboring wind farms. By sharing costs,
wind farms can potentially select the most effective
solution – leading to higher turbine availability and more
energy output.
Constantly improving the way we service your wind farm is vital both to your investment and the industry as a whole.
Our service innovations come both as a result of our own work and as a response to input from the field.
6.0 MW – designed for service efficiency
Service considerations were highly
important during the development of the
SWT-6.0 MW, where the ergonomic nacelle
interior helps technicians perform their tasks
faster and more safely.
Continuous upgrades for
increased energy output
Over the lifespan of a wind farm, new innovations will
steadily help to reduce the Levelized Cost of Energy of
wind energy. Our commitment to modernization and
upgrades enables you to benefit from up-to-date
technology and increased energy output.
One example is our Power Curve Upgrade package,
where adding specially designed components to
legacy turbine blades can result in better aerodynamic
performance and enhanced energy conversion.
And a practical deployment plan is part of the design.
Tablet solution
With service technicians working in high
winds far above the sea, our tablet-based
system reduces ‘paperwork’ compared to
conventional hard copy manuals, safety
documentation and service checklists,
resulting in faster work and quicker, more
accurate service reports.
Accessibility
To make turbine access easier and safer
in higher waves, we have supported the
development of a new access system,
MaXccess, which utilizes boat landing
platforms mounted on the wind turbine
foundations. MaXccess provides safe, stable
access for personnel in higher waves than
previously possible, leading the way to
added turbine availability.
