The present invention relates to methods and apparatus for operating a safety system in a floating wind turbine. The floating wind turbine comprises one or more sensors202, 203, and receives a fore-aft inclination signal from the sensor202, wherein the fore-aft inclination signal indicates an inclination of said floating wind turbine in a fore-aft direction. A side-to-side inclination signal is also received from the sensor203, wherein the side-to-side inclination signal indicates an inclination of said floating wind turbine in a side-to-side direction. An operational parameter of the floating wind turbine is altered based on either or both of said fore-aft inclination signal and said side-to-side inclination signal.
