摘要
采用准动态方法对单点系泊FPSO进行系泊分析,并采用T-N曲线和Miner线性疲劳累积损伤理论以及雨流计数方法对系泊系统进行疲劳分析,研究每一根系泊缆不同位置处的疲劳寿命,研究发现每一根系泊缆触地点位置的疲劳寿命最短。
In this paper, the quasi-dynamic method has been adopted to perform mooring analysis of FPSO with a single point mooring system. It carries out the fatigue analysis of the mooring system by T-N curve, Miner linear cumulative fatigue damage theory, and rainlfow counting algorithm. By the investigation of the fatigue life of different locations at each mooring line, it is found that the fatigue life of touch-down point is the shortest one.
