Project Characteristics
The offshore wind farm ‘alpha ventus’ is located 45 km Northwest of the island Borkum in the German North Sea with water depths ranging from 25 m to 30 m depending on the tide. It is the first offshore wind farm in operation since 2009.
Monitoring of the bathymetry of the seabed around the WTG foundation by multi-beam echo sounder of research vessels revealed significant scour at the tripod foundation, caused by wind, wave, and current.
IMPaC has been contracted for the elaboration of a scour protection concept for the respective WTG tripod foundation.
