The invention discloses an integral offshore wind turbine hoisting device achieving multi-freedom-degree compensation. The hoisting device comprises a hull and a hanging bracket platform. A hanging bracket is installed on the hanging bracket platform. The hoisting device further comprises an upper hoisting point motion compensating system, a hoisting load dynamic matching system, a lower wind turbine locating centering system and a hoisting system. The upper hoisting point motion compensating system is installed on the hanging bracket of the hull and comprises a telescopic suspension arm, a horizontal compensating hydraulic cylinder, a vertical compensating hydraulic cylinder and a related connecting part. The hoisting load dynamic matching system comprises a main bearing steel cable, a main bearing spring, a main bearing hydraulic cylinder and a pulley. The lower wind turbine locating centering system comprises a lower balance beam, a spring buffer, a locating guy rope, a locating winch and a pulley. The hoisting system comprises an upper balance beam, a lifting hook, a hoisting cable, a hoisting cable supporting rod, a pulley and a hoisting winch. The hoisting device can control the posture of a whole wind turbine, and allow the wind turbine to generate compensating motion of six freedom degrees to contend against swinging and heaving of a ship, so that the stability of the wind turbine in storms is improved, and the wind turbine and a foundation are accurately located and centered.
