A procedure and a device in connection with the use of a wind turbine offshore, comprising a wind turbine ( 2 ) connected via a shaft (not shown) 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 ( 6 ) is designed to be anchored so that it can move freely in the vertical plane via a mooring in the form of mooring lines, hinge or tether ( 7 ), whereby, as a consequence of the effect of the waves on the float, the motion of the wind turbine ( 2 ) will act as a damping mechanism on the motion and thus extract energy from the waves. The wind turbine's resonance period is adjusted by adjusting the platform's centre of gravity and/or the tension in the anchor ( 7 ) with which the wind turbine is attached to the sea bed.
