A floating wind turbine comprising a wind turbine rotor 1 mounted on a tower 3 of a spar 4 and tower 3 structure comprising a generally vertical buoyant and deep, ballasted spar 4 moored in a mooring 7 with the turbine rotor 1 connected to a first electrical power generator 11. The floating wind turbine comprising the following features, that the spar 4 and tower 3 structure provided with a buoyant torus 62 arranged at mean water level about the spar 4 and tower 3 structure ; that the torus 62 oscillates with sea waves in an axial direction with a motion relative to the spar 4 and tower 3 structure ,and that the torus 62 is provided with a power take-off system coupled to a second electrical power generator 121.Alternatively the first 11 and second 121 electrical generators may be combined into a single generator driven by both the turbine and the torus. The floating wind turbine will then be more efficient, particularly for the lower wind speed range. |
