The Butendiek offshore wind farm is located in the German Bight, 32km west of the German island Sylt.
The water depth at the Butendiek offshore wind farm is in between 17m and 22m. The wind farm consists of 80 turbines, each with a capacity of 3.6MW giving 288MW in total. The foundation comprises a steel tubular monopile and a transition piece that connects the monopile with the wind turbine's tower. The design and fabrication for the foundations will take place during 2012 with the installation is scheduled for 2013.
Ballast Nedam will use its Heavy Lift Vessel (HLV) Svanen for the installation. HLV Svanen is currently installing foundations at the London Array offshore wind farm in the UK, having recently completed 51 foundations at the Walney 2 offshore wind farm in the Irish Sea. In 2012 the HLV Svanen will be working at the Anholt offshore wind farm in Denmark.
Theo Bruijninckx, CEO of Ballast Nedam: "This contract is an excellent result of our focus on this niche market. It confirms our position as being one of the leading contractors in the emerging European offshore wind market." Ballast Nedam sees good opportunities for further work in the offshore wind market in the years to come.
