    Abstract: A control system for stabilizing a floating wind turbine is provided. The control system includes a measuring device configured for measuring a wind field and a wave field, a determining device wherein the determining device is configured for determining an excitation frequency spectrum of the floating wind turbine on the basis of the measured wind field and/or the wave field and/or a current floater pitch angle of the floating wind turbine, and wherein the determining device is further configured for determining a balanced state of the floating wind turbine, wherein in the balanced state a natural frequency is outside of the excitation frequency spectrum and/or the current floater pitch angle is equal to a pre-defined floater pitch angle. The control system further includes an adjustment device which is configured for manipulating the current floater pitch and/or the natural frequency until the balanced state is met.

    Abstract: A method of controlling wake in a floating wind park is provided. The method includes monitoring a wind condition at at least one of the plurality of floating wind turbines to generate at least a first monitored wind condition, monitoring one or more parameters indicative of a position and/or orientation of at least one of the plurality of floating wind turbines to generate at least a first monitored floating motion state and generating a control parameter based on a parameter set comprising at least the first monitored wind condition and the first monitored floating motion state. The control parameter is derived so as to reduce the wake influence on the downstream wind turbine. The method further includes controlling based on the control parameter, an operation of at least one of the plurality of floating wind turbines.
