Abstract

The invention discloses a floating fan base with flare type tension legs, a marine wind-driven generator and a construction method. The floating fan base comprises a top supporting platform, a bottom supporting structure, at least three hollow stand columns and a ballast regulating system, wherein the top supporting platform is used for supporting a pylon, blades and a wind-driven generator set; the bottom supporting structure is connected with multiple tension legs; the top supporting platform is connected with the bottom supporting structure via the hollow stand columns, the hollow stand columns are arranged around the vertical center line of the floating fan base, and each stand column inclines outwards from a lower end to an upper end relative to the vertical center line of the floating fan base; the ballast regulating system is arranged in the stand columns and / or the bottom supporting structure. The marine wind-driven generator of the base with the structure has excellent movement performance, integral wet towing can be performed, and the floating fan base and the marine wind-driven generator are convenient to manufacture, assemble and mount.

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 ...
