海上风电导管架基础靠船件碰撞特性分析

Collision Characteristics Analysis on the Barge Bumper of Offshore Wind Turbine Jacket Foundation

对船体与导管架基础靠船件撞击的相关理论进行阐述,并以广东某海上风电机组导管架基础靠船件为研究对象,基于非线性有限元分析软件USFOS模拟不同船舶质量和船速停靠的工况。通过各工况加载分析,得出该导管架基础靠船件可以承受的最大撞击能量值以及结构基底剪力与船重、船速的关系。针对行业内已知较大的运维船,计算得出满足要求的靠船件最小尺寸。该分析方法可为以后的靠船件设计提供一定参考。

This paper introduced relevant theories on collision of ships and jacket barge bumpers,based on the nonlinear finite element analysis software-USFOS,taking one barge bumper of an offshore wind turbine jacket foundation in Guangdong as the research object,different amount of energy was applied on the barge bumper to simulate the load cases of different masses and velocities of ship.By analyzing the different cases,the maximum energy that the jacket barge bumper can bear and the relationships of the structural base shear force and ship mass and ship velocity are obtained.For the majority of large maintenance ships in the industry,the minimum size of the barge bumper that can meet the requirements is calculated.And this analysis method can provide some reference for the future design of the barge bumper.
