FLARE-TYPE TENSILE LEGS FLOATING WIND TURBINE BASE, OFFSHORE WIND TURBINE AND CONSTRUCTION METHOD

摘要

A flare-type tensile legs floating wind turbine base; the floating wind turbine base comprises a top support platform (9) for supporting a tower frame (3), blades (1) and a wind turbine set (2); a bottom support structure (7) connecting to a plurality of tensile legs (5); at least three hollow upright columns (6) connected between the top support platform (9) and the bottom support structure (7), and arranged around the vertical central line of the floating wind turbine base, each upright column (6) inclining outward from the lower end to the upper end relative to the vertical central line of the floating wind turbine base; and a ballast adjustment system disposed in the upright columns (6) and/or the bottom support structure (7). Also disclosed are an offshore wind turbine having the floating wind turbine base and a construction method.
