Presentation outline



Licensed wind farms in the North Sea

WAB members


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 €


Offshore Issues

• Prototyping 5 MW class turbines onshore needed

• Development, design and serial production of tripod foundations for water depths >25 meter

• Operation logistics & transport due to port distance

• Improved reliability


Political R&D 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 R&D-Projects


R&D 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


R&D 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

1:10 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


Example 2: Tripod-Foundations

• 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

WeserWind GmbH Offshore Construction Georgsmarienhütte


Example 3: Infrastructure „Luneort“

• 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

BIS, Bremerhaven economic development agency


Example 4: Output power forecasting

• Optimized offshore wind farm power prediction model• Using physical

turbine characteristics

• Forecast of offshore turbine loads for O&M

• Improved forecast of power output for grid operators

• 15 minutes resolution of forecast

Meteocontrol GmbH / Energy & Meteo Systems GmbH


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

R&D project by Windforce GmbH• WAVEMON dynamic load monitoring system

• Glass fibre fast load analysis

• Installed in foundation to analyse wave loads


Outline



Conclusion

• Succesfull regional R&D 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 R&D 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


WAB Offshore Conference: windforce06

• 29th and 30th of June 2006, Bremerhaven

• Compact overview of offshore developments in Germany (and Europe)

• Simultaneous translation available
