菱形风电运维平台结构设计与强度分析

Structural design and strength analysis of rhomboidal wind power operation and maintenance platform

随着海上风电场的开发逐步走向深海,对风电运维模式要求也愈发严格。本文提出以风电运维平台为中转站运维模式设计的一种菱形风电运维平台。在舷侧结构在浮式风电运维生活平台方案设计的基础上,对平台浮体提出2种结构方案,运用SESAM中Genie模块建立菱形平台有限元模型,确定边界条件和约束,施加环境载荷,对这2种结构方案在各工况下进行有限元强度分析,对比校核,最终得到结构强度满足要求且运维效率更高更安全可靠的平台结构。

As the development of offshore wind farms gradually goes to the deep sea,the requirements for wind power operation and maintenance mode are becoming increasingly strict.This paper proposes a kind of diamond offshore wind power living platform designed with the offshore wind power living platform as the transfer station operation and maintenance mode.Based on the design of the floating wind power platform for the side structure,two structural schemes are proposed for the floating body of the platform.The Genie module in SESAM is used to establish the finite element model of the diamond platform,determine the boundary conditions and constraints,and impose environmental loads.The finite element strength analysis of these two structural schemes is carried out under various working conditions.Finally,a platform structure with higher operation efficiency and higher safety and reliability is obtained through comparison and checking.
