Abstract
A method for controlling an inclination of a floating wind turbine platform comprising a generator, a set of turbine blades connected to a shaft inside a turbine nacelle, the turbine nacelle being mounted onto a tower, and at least three stabilizing columns is presented. Each of the at least three stabilizing columns have an internal volume for containing ballast. Position data associated with an orientation of the floating wind turbine is received. A heel angle in reference to the floating wind turbine platform is determined based on the position data. A first signal for adjusting at least one of a blade pitch of the set of turbine blades, and a torque of the generator is sent based on the determined heel angle. A second signal for distributing the ballast among the at least three stabilizing columns is also sent. The second signal for distributing the ballast is based on the determined heel angle and the first signal.
