Floating offshore wind turbine with combination of damping means

摘要

The present invention relates to an offshore wind turbine on a floating support structure (1) comprising in combination: a main floater (1) comprising a part of substantially cylindrical shape, a concrete circular element (2) having a diameter greater than the diameter of the main floater, providing a stationary mass at the base of the floater and a damper, supplementary permanent ballast (4) arranged at the base of the main floater, dynamic ballast boxes (3) included in the main floater and distributed ringwise on the periphery of the floater.
