SPAR-TYPE FLOATING BODY STRUCTURE FOR WIND POWER GENERATION ON OCEAN, MANUFACTURING METHOD OF THE SAME, AND INSTALLATION METHOD OF THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a spar-type floating body structure for wind power generation on the ocean, a manufacturing method of the same, and an installation method of the same, reduced in weight, with large restoring force and short-term manufacturing.

SOLUTION: This spar-type floating body structure 1 for the wind power generation on the ocean includes: a hollow lower floating body 3 formed by joining upper and lower lid bodies 10, 11 to cylindrical precast concrete blocks 7 continuously placed between the lid bodies by PC steel material 12; a hollow upper floating body 2 composed of an upper lid 15 and precast concrete blocks 13 smaller in a diameter than the precast concrete blocks 7 and joined to the lower floating body 3 by the PC steel material 12; and a ballast tank 6 joined to the lower surface of the lower floating body 3 through connecting steel pipes 5.
