A floating structure 1 having three buoyant bodies 3,5,7 for supporting a horizontal axis wind turbine 6 and wind turbine tower 27. The floating structure is suitable for connection to a geostationary mooring system that permits it to weathervane in order to head the wind turbine into the wind. The floating structure also has a wind turbine tower mount 29 for supporting the wind turbine tower. A central buoyant body 3 is located partially above water during assembly and tow out from port and is ballasted so that it is underwater when moored offshore, such that the floating structure becomes a semi-submersible. The three buoyant bodies may be ship shaped in form which reduces loads in the mooring system during operation, and may be made from stiffened flat plates, which are easier for many yards and fabrication shops to make, compared to cylindrical hulls.
