The present invention relates to an offshore wind turbine on a floating support structure () comprising in combination: a main floater () comprising a part of substantially cylindrical shape, a concrete circular element () 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 () arranged at the base of the main floater, dynamic ballast boxes () included in the main floater and distributed ringwise on the periphery of the floater.

The present invention relates to a floating mounting () which includes ballasting means () in order to vary the draught of the floating mounting. The floating mounting () according to the invention has a depth-variable horizontal cross-section, such that the second moment of area of the cross-section of the floating mounting, at the buoyancy surface (Sd), is higher when the floating mounting is deballasted, compared with the second moment of area of the buoyancy surface of the floating mounting, at the buoyancy surface (Sb), when the floating mounting is ballasted.

A wind power system includes a wind turbine resting on a floating support and an anchoring system for anchoring the wind power system connected to the wind power system by attachment points. The wind power system has the attachment points raised above the waterline of the floating support to a height with respect to the waterline determined so as to counterbalance an overturning moment of the wind turbine subjected to a given wind speed.
