摘要
本文以某改装300000 DWT级FPSO为研究对象,采用全船有限元方法对其总纵强度进行研究。本计算采用SESAM软件,通过建立全船有限元模型、水动力模型、应用三维辐射-绕射理论进行波浪载荷预报,依照规范要求确定设计波。在此基础上对全船结构在相应设计波载荷作用下的强度和变形进行分析。
In this paper,the whole ship finite element method is used to analyze the longitudinal strength of a 300000 DWT FPSO conversion.The finite element structure model and hydrodynamic model of the whole ship are established by SESAM software.The wave load is predicted according to the 3D radiation-diffraction theory,and the design wave parameters of different loads are determined according to the rules.On this basis,the strength and deformation of the whole ship structure under its design wave load are obtained.
