11. A method for stabilizing a floating wind turbine, the method comprising:
monitoring an offset from a predetermined floater pitch angle and/or an offset from a predetermined floater yaw angle of the floating wind turbine;
monitoring an oscillating motion of the floater pitch angle and/or an oscillating motion of the floater yaw angle;
wherein the predetermined floater pitch angle and the predetermined floater yaw angle define a predetermined balanced state of the floating wind turbine;
wherein a threshold of the oscillating motion of the floater pitch angle and a threshold of the oscillating motion of the floater yaw angle further define the predetermined balanced state of the floating wind turbine;
manipulating the floater pitch angle and/or the floater yaw angle until the predetermined balanced state is met; and
manipulating the oscillating motion of the floater pitch angle and/or the oscillating motion of the floater yaw angle until the predetermined balanced state of the floating wind turbine is met.
