  • Floating device supporting an offshore wind turbine, and corresponding floating wind turbine unit
    Patent number: 10787233
    Abstract: A floating device for supporting an offshore wind turbine, comprising a central floating pillar for fixedly receiving a tower of the wind turbine, at least three peripheral floaters, and one leg per floater, each leg extending in a longitudinal direction that runs radially in relation to the central pillar; each leg has a proximal end that is secured to the central pillar, and a distal end that is secured to the floater; the legs include an outer tubular element, which extends in the longitudinal direction of the leg and has a curved cross-section perpendicularly to the longitudinal direction, and an inner tubular element, which extends in the longitudinal direction of the leg and has a polygonal cross-section perpendicularly to the longitudinal direction, the polygonal cross-section being inscribed in the curved cross-section. The invention also relates to a floating wind turbine unit comprising the device and a wind turbine.
