| 摘 要： | 在研究谱分析法基本原理的基础上，搭建了基于SESAM软件的海洋平台节点疲劳寿命评估流程，应用该流程完成了某自升式平台桩腿的疲劳寿命评估，针对该方法中需要输入的S—N曲线、波浪谱、JON—SWAP谱的不同伽马参数、波浪散布图等关键参数进行了敏感性分析，得到的结果和建议可供工程设计时参考。

| Abstract: | Though the study of the basic principle of this method,a fatigue analysis procedure based on SESAM software is established for the tubular joint of the offshore platform. Then the fatigue life assessment for a jack-up drilling platform is performed using the procedure mentioned above. Finally the sensitive analysis is carried out for ttie key factors that needed to be selected, such as S-N curve, wave spectrum, different gamma parameters of JON- SWAP spectrum and wave scatter diagram, the result and suggestion obtained can provide reference for the engineering. |
