Abstract

The invention relates to a pile-shoe-shaped semi-submersible type at-sea wind power platform. The platform comprises an at-sea floating wind generator unit, a unit supporting vertical post, outer vertical posts, transverse supporting structures and outer vertical post pile-shoes, wherein the three outer vertical posts are positioned in three top points of an equilateral triangle, the unit supporting vertical post is located at the central position of the equilateral triangle, and the at-sea floating wind generator unit is mounted above the unit supporting vertical post. The bottoms of the three outer vertical posts are provided with the outer vertical post pile-shoes, and no connection exists between the three outer vertical posts. The portions between the three outer vertical posts and the unit supporting vertical post are connected through the transverse supporting structures so as to form a stable semi-submersible type at-sea wind power platform structure. The pile-shoe-shaped semi-submersible type at-sea wind power platform has the advantages of being better in stability and motion performance, light in weight, low in cost, low in manufacturing difficulties and the like.

Description

technical field [0001] The invention relates to a spud shoe type semi-submersible offshore wind power platform, which belongs to the technical field of offshore floating wind power equipment. Background technique [0002] In recent years, the state has vigorously advocated the development of offshore wind power. With the full development and utilization of offshore wind farms, the fixed offshore wind power platforms in the form of pile foundations have been saturated. Waters farther offshore have better wind resources and are more suitable for offshore wind power development. Due to the limitation of water depth, fixed pile foundations are difficult to apply to sea areas with water depths exceeding 50m, and the concept of floating wind power platforms emerged as the times require. At present, there are four main schemes for floating wind power platforms: SPAR type, TLP type, semi-submersible type and barge type. Due to the limitation of the applicable water depth, SPAR ca...
