Development of offshore wind energy is desired as a countermeasure against global warming. This article presents motion analysis of a floating offshore wind turbine during the rotor-rotation under wind loads. A 2 MW downwind turbine is mounted on a floating foundation of the spar-type. The wind loads acting on the rotor blades are calculated using the blade element momentum theory. The multibody dynamics system theory is employed to consider the effect of the rotor-rotation. As a result, the motion of yaw, sway and roll are generated due to the effect of the gyro-moment for the rotor-rotation.
