Netherlands-based Ballast Nedam has signed a contract worth approximately 250 million euros with German developer wpd for the engineering, supply and installation of 80 foundations at the Butendiek offshore wind farm in Germany.
Ballast Nedam will use its Heavy Lift Vessel (HLV) Svanen for the installation of the foundations. Each foundation comprises a monopile (steel tubular pile) and a transition piece that connects the monopile with the wind turbine's tower. The design and fabrication of the foundations will take place in 2012, and the installation is scheduled for 2013.
The Butendiek offshore wind farm is located in the German Bight, 32 km west of the German island Sylt. The wind farm consists of 80 turbines, each with a capacity of 3.6 MW, for a total of 288 MW. The companies expect the financial closing for the project to occur by the end of this year.
