Offshore wind turbine on a floating mount comprising a combination of shock-absorbing means

The present invention concerns an offshore wind turbine on a floating mount (1) comprising, in combination: - a main float (1) comprising a portion substantially cylindrical in shape, - a circular concrete element (2) of which the diameter is greater than the diameter of the main float forming both a fixed mass at the base of the float and shock-absorbing means, - additional permanent ballast means (4) located at the base of the main float, - dynamic ballast boxes (3) included in the main float, and distributed in a ring at the periphery of said float.
