Abstract
A floating body () for a spar-type offshore wind power generation facility floating sideways is raised by injecting ballast water at sea, by steps including a first step of decentering a center of gravity of the floating body for the spar-type offshore wind power generation facility by means of a center-of-gravity decentering device, and a second step of injecting the ballast water to raise upright the floating body for the spar-type offshore wind power generation facility. The center-of-gravity decentering device may be a weight () attached to an outer surface of the floating body, or a solid ballast () introduced in the floating body.
