A method is for operating a wind turbine having a tower, a rotor with a rotor blade and a generator coupled to the rotor. The wind turbine further includes a pitch setting system for changing the pitch angle of the rotor blade and a generator controller for controlling the generator torque. The method includes providing first information representative of at least two motion variables. The motion variables are motion variables of an oscillation of the tower and/or of an oscillation of the rotor blade. Then, an operating setpoint is determined for the pitch setting system and the generator controller depending on the first information. The operating setpoint is determined such that, when the pitch setting system and/or the generator controller is operated according to the respective operating setpoint, it sets the pitch angle of the rotor blade or the generator torque, respectively, in order to damp the oscillation.

A floating wind turbine platform is disclosed. The floating wind turbine platform may include a floatable structure that is deployable to a body of water and includes a plurality of semisubmersible columns. The semisubmersible columns may be interconnected. Each semisubmersible column can define an internal ballast volume. An intake port in each semisubmersible column can place the internal ballast volume of the semisubmersible column into fluid communication with the body of water. A ballast control system may be provided to balance the floatable structure upon a detected inclination thereof. Balancing of the floatable structure may be accomplished by selectively controlling a transfer of water from the body of water to the internal ballast volume of at least one of the semisubmersible columns, and/or by selectively controlling a transfer of water from the internal ballast volume of at least one of the semisubmersible columns to the body of water.
