PURPOSE: An offshore wind turbine, a crane for installing the offshore wind turbine, and a method for installing the offshore wind turbine using the same are provided to reduce wind resistance as a flow separation layer is not formed. CONSTITUTION: An offshore wind turbine includes a tower(11), a nacelle(12), and a blade(13). The tower is extended to upper and lower directions, and installed on the mounting post(P) of the sea. The nacelle is installed on the upper end of the tower, and a power generator is installed the inside of the nacelle. The blade is rotationally installed at one side of the nacelle, and rotated by wind generating electricity. A recessed groove is dented on the outer surface of the tower in a diameter direction. A clamping unit for lifting or unloading the tower is fixed in the recessed groove. |
