Floating body device supporting an offshore wind turbine and corresponding floating wind turbine unit

摘要

The present invention is a floating body device (2) for supporting an offshore wind turbine (1), the floating body central column (21) fixedly receiving the tower (12) of the wind turbine (1), and at least three peripheries. A floater (22) and one leg (23) per floater, each leg (23) extending in a longitudinal direction running radially relative to the central column (21), each leg (23) A leg (23) having a proximal end secured to the central post (21) and a distal end secured to the floater (22), the leg (23) being the longitudinal length of the leg (23) An outer tubular element extending in the direction and having a curved cross section perpendicular to the longitudinal direction, and an inner tubular extending in the longitudinal direction of the leg (23) and having a polygonal cross section perpendicular to the longitudinal direction The element, the polygonal cross section is inscribed in the curved cross section And a Jo element relates to floating apparatus (2). The invention also relates to a floating wind turbine unit comprising the aforementioned device and a wind turbine.
