Abstract
The present invention provides a floating offshore wind turbine capable of suppressing yawing of a nacelle caused by a gyro effect which is a cause of adverse influence of power generating efficiency of a wind turbine and endurance of devices thereof. The floating offshore wind turbineincludes a rotorwhich is rotated by wind, a nacellein which a rotation shaftof the rotoris accommodated, and a towerincluding a turning seated bearingwhich supports the nacellesuch that the nacellecan turn with respect to a sea surface P to exert a weathercock effect. The tower is provided with yawing suppressing meanswhich suppresses yawing T of the nacelle. According to this, it is possible to suppress the yawing T of the nacellegenerated by a gyro effect caused by yawing Ω generated in the floating bodyby waves of the sea surface P.
