摘要
文章介绍了对海洋平台桩靴的疲劳寿命进行仿真的相关技术,在合理简化的基础上建立其桩腿与桩靴的有限元分析模型。利用数字仿真软件及相关法规指南计算海洋平台的疲劳生命期,所得结果能帮助设计人员在评估各项权衡因素时做出相对明智的抉择,从而实现预期的寿命,并对优化平台结构、保证平台安全可靠作业等方面具有重要意义。
The paper introduces the related technologies for simulating the fatigue life of spudcan for offshore platforms,and builds a finite element analysis model of its legs and boots on the basis of reasonably simplification.The fatigue life of spudcan for offshore platforms is calculated using digital simulation software and related regulatory guidelines.The results can be of great significance for engineers to make relatively wise choices when evaluating various trade-off factors,so as to achieve the expected life,and to optimize the structure to ensure the safe and reliable operation of offshore platforms.
