摘要
基于近年来胜利海上固定平台主结构检测出疲劳裂纹的实际,分析了传统的基于波浪荷载的简化疲劳分析结论与实际检测结果的差异性和不足之处,提出开展基于冰荷载的详细疲劳分析的必要性。在此基础上,总结了国内海上固定平台结构冰激疲劳的研究现状,提出了在胜利油田海域开展平台结构冰激疲劳分析能够利用的现有成果,以及需要继续开展相关研究方向的建议。
Based on the fact that fatigue cracks have been detected in the main structures of Shengli offshore fixed platforms in recent years,this paper analyzes the differences and shortcomings between the traditional simplified fatigue analysis results based on wave load and the actual test results,and puts forward the necessity of carrying out detailed fatigue analysis based on ice load.On this basis,the current research status of ice induced fatigue of offshore fixed platform structures in China is summarized,and the existing achievements that can be used to carry out ice induced fatigue analysis of platform structures in Shengli Oilfield are put forward,as well as the suggestions for further research direction.
