Abstract

The invention discloses a marine wind turbine generator system and a floating foundation thereof. The floating foundation comprises a foundation main body (3). The foundation base main body (3) comprises a first outer frame (34) and a first airbag (31) arranged in the first outer frame (34). By means of the floating foundation, the manufacturing cost of the foundation main body (3) can be significantly reduced, high enough strength is provided for supporting the whole marine wind turbine generator system, the economy and durability are improved, meanwhile, load transmitted from the top to bottom can be reliably transmitted to seawater to provide buoyancy for the marine wind turbine generator system, and the stability of the marine wind turbine generator system is improved.

Description

technical field [0001] The invention relates to the technical field of offshore wind power generation, in particular, the invention relates to an offshore wind power generating set and a floating foundation thereof. Background technique [0002] At present, the floating foundations of offshore wind turbines generally have various types of foundations such as column type, tension leg type, semi-submersible type and barge type. Because the total weight of the tower and the nacelle installed on the tower of the offshore wind power generating set is relatively large, the requirements for the structural strength and the buoyancy that can be provided by the floating foundation are relatively high. The foundation structure of an existing floating platform offshore wind turbine adopts a steel plate closed foundation, that is, the steel plate is used to form a floating closed space. Similar floating foundations are closed empty boxes, and some floating foundations use Closed columns...
