Abstract

Three dimensional (3D) non-linear finite element analysis of offshore pipeline is investigated in this work with the help of general purpose software Abaqus. The general algorithm for the finite element approach is introduced. The 3D seabed mesh, limited to a corridor along the pipeline, is extracted from survey data via Fledermous software. Moreover soil bearing capacity and coefficient of frictions, obtained from the field survey report, and are introduced into the finite element model through the interaction module. For a case of study, a 32inch pipeline with API 5L X65 material grade subjected to high pressure and high temperature loading is investigated in more details.

基于Abaqus的海底管道三维构型分析

本文利用通用软件Abaqus对海洋管道进行三维非线性有限元分析。介绍了有限元法的一般算法。通过Fledermous软件从调查数据中提取出仅限于管道沿线走廊的3D海底网格。并通过交互作用模块将实测报告中土体承载力和摩擦系数引入有限元模型。以API 5L X65材料等级的32英寸管道为例，对高压高温载荷进行了详细研究。
