Floating units for supporting an offshore wind turbine and corresponding floating wind turbine units

摘要

The present invention relates to a floating device (2) for supporting a marine wind turbine (1), comprising a floating floating filler (21) for fixedly receiving a tower (12) of the wind turbine (1) A plotter 22, and one leg 23 per plotter, each leg 23 extending longitudinally in a radial direction relative to the central pillar 21; Each leg 23 has a proximal end fixed to the central pillar 21 and a distal end fixed to the plotter 22; Said legs 23 extending in the longitudinal direction of said legs 23 and having a curved cross section perpendicular to said longitudinal direction and an outer tubular member extending in the longitudinal direction of said legs 23, An inner tubular member having a polygonal cross section, the polygonal cross section being in contact with the curved cross section. The present invention also relates to a floating wind turbine unit comprising said device and a wind turbine.
