【摘要】：运用大型水动力分析软件Orca Flex对置于FPSO与YOKE之间传输电力的跨接缆进行了极值与疲劳仿真分析。针对跨接缆的动态响应分析,采用了非线性时域方法,并考虑了波浪、流、FPSO的一阶运动对跨接缆的作用,进而对跨接缆与FPSO连接时的极端荷载效应和长期交变荷载下的疲劳安全性进行了评估。结果表明,该跨接缆的设计满足缆与FPSO连接时的极值准则,但与相邻跨接缆之间存在干涉风险。
[Abstract]:The extreme value and fatigue analysis of the cross-connection cable placed between FPSO and YOKE are analyzed by using the large-scale hydrodynamic analysis software Orca Flex. In this paper, the nonlinear time domain method is used to analyze the dynamic response of span cable, and the effect of the first order motion of wave and current FPSO on the span cable is considered. Furthermore, the extreme load effect and fatigue safety under long term alternating load are evaluated when the span cable is connected with FPSO. The results show that the design of the straddle cable satisfies the extremum criterion when the cable is connected with FPSO, but there is a risk of interference between the cable and the adjacent cable.
