METHOD FOR ASSEMBLING FLOATING WIND-POWER GENERATION DEVICE, AND FLOATING WIND-POWER GENERATION DEVICE

摘要

A method is for assembling a floating-body wind turbine power generating apparatus 1 which at least includes: a floating body 20 including at least one column 22 and configured to float on water surface; and a tower 6 erected on the at least one column 22. The method includes a tower erecting step of erecting the tower 6 on the at least one column 22 by joining the at least one column 22 and the tower 6 to each other by welding. In the tower erecting step, the tower 6 and the column 22 are joined to each other by embedding a base end side of the tower 6 into the column 22, and welding an outer circumferential surface and/or an inner circumferential surface of an embedded section 28 to the column 22 over a predetermined length in an axial direction of the tower 6.
