Floating wind turbine with wave energy converter

Madjid Karimirad (Inventor)

Research output: Patent


The invention is a floating wind turbine comprising - a wind turbine rotor (1) mounted on a tower (3) of a spar and tower structure (4, 3) comprising a generally vertical buoyant and deep, ballasted spar (4) moored in a mooring (7), - said turbine rotor (1) connected to a first electrical power generator (11). The floating wind turbine comprises the following features: * that the spar and tower structure (4, 3) provided with a buoyant torus (62) arranged at mean water level about the spar and tower structure (4, 3); * that the torus (62) oscillates with sea waves in an axial direction with a motion relative to the spar and tower structure (4, 3), * that the torus (62) is provided with a power take-off system (120) coupled to a second electrical power generator (121). The so modified floating wind turbine will then be more efficient, particularly for the lower wind speed range.
