PROBLEM TO BE SOLVED: To provide a spar-type floating body structure for wind power generation on the ocean and a manufacturing method of the same in which the structure is lightweight, excels in durability, and can be manufactured in a short period of time. SOLUTION: The spar-type floating structure 1 for wind power generation on the ocean includes a lower floating body 3 constructed by integrally joining an upper lid 8 and a lower lid 9 with cylindrical precast concrete blocks 5 and 6 continuously placed between the lid bodies by a PC steel material 10. The structure 1 also includes an upper floating body 2 constructed with a precast concrete block 17 that is smaller in a diameter than the precast concrete blocks 5 and 6 and an upper lid 21, which are integrally joined with the lower floating body 3 by the PC steel material 10. A plurality of ballast tanks 4 are formed with retention walls 11 and 12 below and inside the lower floating body 3. A plurality of water-sealed sectional portions 22 are formed inside the upper floating body 2 by retention walls 19. COPYRIGHT: (C)2009,JPO&INPIT
