摘要： 参考文昌油气田的脐带缆截面设计及具体工作环境参数,利用水动力分析软件OrcaFlex建立了文昌缆与主平台回接过程中的动力学响应模型,计算了在不同浪向下脐带缆在与主平台回接过程中的水动力响应。通过水动力分析结果可知:绞车的牵引速度和浪向的改变对脐带缆的牵拉过程有很大影响;脐带缆发生明显弯曲的部位von mises应力也会发生明显变化,但应力仍小于API 2RD的允许应力,可满足工程安全要求。

Abstract: A dynamics response model are established using hydrodynamic analysis software OrcaFlex and referring to cable cross section design of Wenchang umbilical cable and operation environmental parameters to simulate the dynamic response of J-tube pull-in installation of the main platform for the umbilical cable under different wave directions. Finally, some instructive notices and mechanical properties during umbilical tie-back were put forward based on related modeling results. The hydrodynamic analytical result shows that the speed of the winch and the change of wave directions have very important effects on the process of umbilical cable pull-in through J-tube; the position where umbilical cable bends badly is where the von mises stress changes obviously as well, but the stress is still less than that permitted by API 2RD, and it can satisfy the request by the engineering safety.

Key words: umbilical cable, OrcaFlex, hydrodynamic analysis, different wave directions
