摘要： There is provided a spar-type floating offshore wind power generation facility that suppresses a reduction in power generation efficiency caused by tilting of a tower, suppresses rotational motion (yaw motion) around a vertical axis, prevents a ship from coming into contact with a mooring cable, and, at the same time, appropriately holds the tilted posture state of the tower. A floating offshore wind power generation facility 1 includes a floating body 2, a mooring cable 3, a tower 4, and a windmill 5 installed at the top of the tower 4, the windmill 5 including a nacelle 6 and a plurality of blades 7. The rotation axis of the windmill 5 has a predetermined upward angle to avoid contact between the blades 7 and the tower 4, and the windmill 5 is of a downwind type in which the blades 7 are attached to the leeward side of the nacelle 6 and installed with the back surfaces of the blades 7 facing windward, and the mooring point of the mooring cable 3 to the floating body 2 is set at a position below the surface of the sea and higher than the center of gravity of the floating body 2.

摘要： [Problem]
To safely and efficiently raise upright a floating body for a spar-type offshore wind power generation facility by injecting ballast water at sea.
[Solution]
A floating body 4 for a spar-type offshore wind power generation facility floating sideways is raised by injecting ballast water at sea, by the steps including a first step of decentering a center of gravity of the floating body 4 for the spar-type offshore wind power generation facility by means of a center-of-gravity decentering means, and a second step of injecting the ballast water to raise upright the floating body 4 for the spar-type offshore wind power generation facility. The center-of-gravity decentering means may be a weight 2 attached to an outer surface of the floating body 4, or a solid ballast 34 introduced in the floating body 4.
