We can’t conquer the elementsBut we can outthink them

Wind Service Offshore

Turning unpredictability into outputMassive 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.

We make maintenance a routine, not an adventure

Over 20 years of offshore experience

The reassurance of a strong service partner

The world’s leading training centers

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.

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.

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.

Our service technician training is focused on reducing risks. Not taking them.

Increasing availabilitywith proactive planningOffshore 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.

•Avarietyofdiagnosticsupportservicesisfocusedon

and performance of wind farm control and grid support.

The impressive track record of remote monitoring and

vibration diagnostics, combined with our comprehensive

support services, makes Siemens a trustworthy and reliable

service provider.

Specialist service vessels: saving time, helping enhance your returns

The right craft for every taskBased 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)

Cost-efficientandsafe,CTVsaremostlyusedtotransfer

technicians and components to near shore wind farms.

Formoreremote‘farshore’windfarms,theCTVsarealso

utilized for transfers in combination with either a Service

Operation Vessel or offshore accommodation platform.

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.

Accommodation platform

Providing stable and comfortable accommodation

facilities for a large group of technicians, as well as ample

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 fast-

response 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.

upgrades enables you to benefit from up-to-date

technology and increased energy output.

legacy turbine blades can result in better aerodynamic

performance and enhanced energy conversion.

And a practical deployment plan is part of the design.

IndustrializationThe 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.

Innovative and responsiveConstantlyimprovingthewayweserviceyourwindfarmisvitalbothtoyourinvestmentandtheindustryasawhole.

Our service innovations come both as a result of our own work and as a response to input from the field.

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.

Accessibility

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.

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.
