Project Details for Alpha Ventus
General Information Name Alpha Ventus correct
Other names Borkum West I correct
Country name Germany correct
Region Exclusive Economic Zone (DolWin) (BSH Cluster 2 in Draft Network Plan) correct
Comments Also known as Borkum West I.

Wind Park made up of 6 Multibrid M5000 turbines (Rotor Diameter 116m, Hub Height 90m Total height 148m, Tripod) and 6 REpower turbines (Rotor Diameter 126m, Hub Height 92m Total height 155m, Jacket).

An added benefit of the wind farm is that colonies of oysters, crabs and anemones have begun to populate the turbine bases.
