A procedure and a device in connection with the use of a wind turbine offshore, including a wind turbine ( 2 ) connected via a shaft to a generator ( 3 ), which is rotationally mounted on a tower ( 4 ), and a foundation underneath in the form of a float ( 6 ) on which the tower ( 4 ) is mounted. The float is anchored so that it can move freely in the vertical plane via an anchor or a mooring in the form of mooring lines, hinges or tethers ( 7 ). As a consequence of the effect of the waves on the float, the motion of the wind turbine will act as a damping mechanism on the motion and thus extract energy from the waves. The wind turbine's resonance period can be adjusted by adjusting the platform's center of gravity and/or the tension in the anchor with which the wind turbine is attached to the sea bed. |
