【摘要】：深海FPSO一般由多根錨泊線組成的系泊系統(tǒng)進(jìn)行定位,為保證結(jié)構(gòu)的安全性,開(kāi)展錨泊線疲勞強(qiáng)度評(píng)估分析顯得至關(guān)重要。本文采用改進(jìn)的雨流計(jì)數(shù)法結(jié)合T-N曲線和Miner線性疲勞累計(jì)損傷理論對(duì)某FPSO錨泊線進(jìn)行疲勞性能分析。針對(duì)錨泊線的疲勞損傷,分析其疲勞損傷的不利位置,從而為FPSO系泊系統(tǒng)的維護(hù)提供重要依據(jù)。
[Abstract]:Deep-sea FPSO is usually located by a mooring system composed of multiple mooring lines. In order to ensure the safety of the structure, it is very important to evaluate the fatigue strength of the mooring lines. In this paper, the improved rain flow counting method combined with T-N curve and Miner linear fatigue cumulative damage theory is used to analyze the fatigue performance of a certain FPSO mooring line. Aiming at the fatigue damage of the mooring line, the unfavorable position of the fatigue damage is analyzed, which provides an important basis for the maintenance of the FPSO mooring system.
