A floating wind turbine (1) for electric power production and a method for use of said wind turbine (1), is described, where the wind turbine (1) comprises a hull (2) attached to a supporting column (2′) for a wind turbine (3) which is arranged to be put into rotation by wind force acting on rotor blades (3′), the wind turbine (1) is connected to a buoyancy device (4) by means of a coupling device (5), the buoyancy device (4) is arranged encircling at least a portion of the hull (2), and the buoyancy device (4) is arranged to be able to support at least a portion of the mass of the wind turbine (1), the coupling device (5) is a rotary coupling arranged in such a way that the wind turbine (1) is arranged to be able to rotate an angle from an essentially vertical position towards a horizontal position, or the opposite, and the hull (2) is provided with an adjustable ballast means (9, 12) arranged to be able to balance the wind turbine (1) about the rotary coupling (5) in any position between said positions.
A floating wind turbine (1) for electric power production, the wind turbine (1) comprises:
A method for controlling a vertical extent of a floating wind turbine (1) for production of electric power, in connection with transport and maintenance, the wind turbine (1) comprises a hull (2) attached to a supporting column (2′) for a wind turbine (3) arranged to be rotated by wind force acting on rotor blades (3′), the wind turbine (1) is connected with a buoyancy device (4) arranged at least partially encircling at least a portion the hull (2), and which is arranged to support at least a portion of the mass of the wind turbine (1), the method comprises the following steps:
