Abstract
It is described a method of controlling an offshore wind turbine (50) installed on a floating platform (12) and having at least one rotor blade (6) comprising at least one adaptable flow regulating device (9) configured to adapt/modulate an air flow exposed profile, the method comprising: receiving a load related signal (3, 14) indicative of a load due to a movement of the floating platform (12); and controlling the adaptable flow regulating device (9) based on the load related signal (3, 14).

1-12. (canceled)
A method of controlling an offshore wind turbine installed on a floating platform and having at least one rotor blade comprising at least one adaptable flow regulating device configured to adapt/modulate an air flow exposed profile, wherein the at least one rotor blade is adjustable regarding a pitch angle using a pitching system, the method comprising:
- receiving a load related signal indicative of a load due to a movement of the floating platform;
- filtering the load related signal to obtain a filtered load related signal;
- controlling the at least one adaptable flow regulating device based on the filtered load related signal such as to counteract or dampen at least one load which is due to the movement of the floating platform;
- receiving a wind turbine operation related signal;
- filtering the wind turbine operation related signal to obtain a filtered wind turbine operation related signal;
- and
- controlling the pitching system based on the filtered wind turbine operation related signal.
