Abstract

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.

Description

technical field [0001] The present invention relates to the field of offshore wind power generators, and more specifically, relates to an outward-floating tension-leg floating wind turbine foundation, an offshore wind power generator with the floating wind turbine foundation, and an installation and construction method for the offshore wind power generator. Background technique [0002] In the deep sea area above 50 meters, there are more and better wind resources that can be developed and utilized, and the market prospect is also broader. To develop deep-sea wind farms in these sea areas, it will not be advantageous to fix the various through-pile structures on the seabed that are commonly used in offshore wind farms, because: as the water depth increases, the cost of fixed foundations rises linearly; fixed offshore wind turbines The cost of construction and operation and maintenance is higher than that of floating offshore wind turbines. Therefore, in order to enable the ...
