Multi-point mooring structure suitable for offshore floating fan and offshore wind driven generator

Abstract

The invention belongs to the technical field of ocean engineering, and discloses a multi-point mooring structure suitable for an offshore floating fan and an offshore wind driven generator, wherein the multi-point mooring structure comprises a fan platform and a plurality of groups of mooring lines, one end of each group of mooring lines is connected with the fan platform, the other end of each group of mooring lines is connected with an anchoring point, and the anchoring point is arranged on the seabed; the fan platform is cylindrical, and a plurality of groups of mooring lines are uniformlydistributed around the central shaft of the fan platform; the fan platform is provided with two rows of guide cable holes, the two rows of guide cable holes are arranged at intervals in the length direction of the fan platform, and the two rows of guide cable holes are arranged in a crossed manner; And one end of each group of mooring lines is respectively connected with the two rows of guide cable holes. The structure can effectively solve the problem of overlarge motion response of the offshore floating fan under the wind wave load, can obviously reduce the rolling motion of the fan, and improves the stability.

Description

technical field [0001] The invention belongs to the technical field related to marine engineering, and more specifically relates to a multi-point mooring structure suitable for offshore floating wind turbines and an offshore wind power generator. Background technique [0002] In recent years, offshore wind energy technology has developed rapidly all over the world, which has also promoted people's research on offshore floating wind turbines. In fact, offshore floating wind turbines will have a motion response under wind and wave loads. Therefore, reducing the motion response of offshore floating wind turbines has always been a hot spot in domestic and foreign projects. Most of the research is to reduce the motion response by improving the structure of the floating wind turbine platform. However, this also increases the difficulty of construction and maintenance costs accordingly. Unlike land-based wind turbines, offshore wind turbines rely on their mooring systems to maintai...

AI Technical Summary

Problems solved by technology

The plurality of fairleads of the multi-point mooring structure are divided into two rows, and a mooring line includes three upper bifurcated mooring lines connecting the fairleads and connecting nodes and the lower mooring lines connecting anchor points and connecting nodes line, which can effectively solve the problem of excessive motion response of offshore floating wind turbines under wind and wave loads, and can significantly reduce the rolling motion of wind turbines. The structure design is reasonable, construction difficulty and maintenance cost are low, and it is extremely practical. sex
