PROBLEM TO BE SOLVED: To provide a spar type floating body offshore wind turbine generator facility in which a reduction of generating efficiency caused by inclination of a tower is restricted, a rotating motion (yawing motion) around a vertical shaft is restricted, further a ship is prevented from being contacted with a mooring rope and at the same time an inclined attitude of the tower can be properly held.SOLUTION: This invention relates to a floating body offshore wind turbine generator facility 1 constituted by a floating body 2, mooring rope 3, tower 4, nacell 6 installed at the top part of the tower 4 and a wind turbine 5 composed of a plurality of blades 7. The wind turbine 5 is of a down-wind type in which its rotation axis is inclined upward by a prescribed angle in order to avoid contact between the blade 7 and the tower 4, the blade 7 is attached to a downstream side of the nacell 6 and the rear surface of the blade 7 is installed while facing upstream side, the mooring point of the mooring rope 3 to the floating body 2 is under sea level and set at a higher position than a center of gravity of the floating body 2. |
