Goals of WAB

Support regional innovative structures for wind
energy
Strengthen wind energy network in
Northwest-German coastal region
Initiate and facilitate research, development and
demonstration project for on- and offshore wind
energy
Facilitate cooperation between wind and maritime
industry - Offshore
Initiate and coordinate qualification and
education projects
Identification of necessary structures and
ressources for offshore wind

Licensed wind farms in the North Sea
WAB members
10
Applications for offshore wind farms

9 licences have been granted by the federal
licensing authority BSH in the North Sea
Max. 80 Turbines per wind farm
3.5 5 MW turbines proposed
2,000 3,000 MW rated power, depending on
turbine size
Value 3 6 Billion

11
Offshore Issues

Prototyping 5 MW class turbines onshore needed
Development, design and serial production of
tripod foundations for water depths gt25 meter
Operation logistics transport due to port
distance
Improved reliability

Political RD Strategy

Strategy by the Federal State of Bremen developed
in 2002
Focus on offshore needs
Industry network building
Wind Energy Agency Bremerhaven/Bremen
fk-wind additional scientific network
Infrastructure development for prototyping and
offshore serial production
Support program of RD-Projects

14
RD program support characteristics

Supported projects need to be strong business
driven
Projects relatively close to market needs and
realisation
50.000 - 200.000 funding per project
50 funding limit for businesses
75 funding limit for scientific institutes
Focus on offshore-related projects

15
RD supported projects

2000-2006 More than 60 projects
Overall funding approx. XYZ Million
Main project focus was on offshore (as intended)
Many developments also suitable for onshore use

Example 1 Turbine development

Multibrid Entwicklungsgesellschaft mbH

Multibrid M5000 Turbine
5 MW, specially designed for offshore use
Single stage robust planetary 110 gear
Special air conditioning system using tower as
overpressure chimney
Comparatively low nacelle weight of approx. 300
tonnes
Operating since December 2004
Research on operation, materials, climate
influences

18
Example 2 Tripod-Foundations
WeserWind GmbH Offshore Construction
Georgsmarienhütte

Optimised tripod design
Weight reduction
Serial manufacturing
Cost optimisation
Combination with concrete elements
Corrosion protection
Installation possibilities
Will be installed onshore with 2nd Multibrid
M5000 Prototype in 2006

19
Example 3 Infrastructure Luneort
BIS, Bremerhaven economic development agency

Development of industrial harbour site Luneort
for offshore wind development
Full logistical analysis of offshore value chain
Simulation of logistical processes on-site
Development of a tailor-made concept for area
development

20
Example 4 Output power forecasting
Meteocontrol GmbH / Energy Meteo Systems GmbH

Optimized offshore wind farm power prediction
model
Using physical turbine characteristics
Forecast of offshore turbine loads for OM
Improved forecast of power output for grid
operators
15 minutes resolution of forecast

21
Example 5 Dynamic foundation loads

Meteorological mast Amrumbank West
Built by Hochtief AG and WeserWind GmbH
90 meters high,22 meters water depth
Commissioned by Essent Wind Deutschland GmbH,
E.ON

RD project by Windforce GmbH
WAVEMON dynamic load monitoring system
Glass fibre fast load analysis
Installed in foundation to analyse wave loads

Conclusion

Succesfull regional RD programme
Focus on near-market industry needs is decisive
in this stage of offshore wind development
Inclusion of other regional sectors expertise
(aircraft, material research, maritime) necessary
to reach critical mass and to create added value
The RD program created strong links between
industry and (a distributed) scientific community
Financial project size fits industry needs well
Clear view on overall regional business
innovation developments needed in advance
