摘要
自升式平台在作业时承受风、浪、流等环境作用。以CIMC400自升式平台为例,基于非线性倒塌分析法和结构参数的随机分布,对平台极限承载力进行确定性以及可靠性分析,并进一步就构件受损和疲劳、腐蚀对平台极限承载力的影响进行了研究,为这类平台的结构设计提出了一些有益的建议。
Wind, wave and current are the primary environment loads for a Jack-up unit in operation condition. In this paper, a CIMC400 Jack-up unit iS taken as an example, for which random distributions of structure parameters are considered. Ultimate bearing capacity is evaluated with both deterministic and reliable analysis based on nonlinear push over method. Effects of damaged components, fatigue and corrosion are studied. Finally, several practical suggestions to structure design of this kind of offshore installations are summarized.
