Foundation structure for water wind power generator, water wind power generator, and method for manufacturing water wind power generator

摘要

PROBLEM TO BE SOLVED: To easily install and stably hold a wind power generation part at an offshore installation position at low cost.SOLUTION: A foundation structure 30 for an on-water wind power generator 10 uses a floating part 31 to hold a wind power generation part 20 at an offshore installation position P. The floating part 31 includes: a floating body 33 having a buoyancy body 35 and a plurality of leg members 36, the buoyancy body being disposed in water and supporting the wind power generation part 20, the leg members 36 extending from the buoyancy body 35 toward a water bottom B and being circumferentially arranged around the buoyancy body 35 in a planar view of the floating part 31; and a weight 34 attached to the ends at the water bottom B side of the leg members 36 at the installation position P.
