摘要
针对水下基座下放过程中的基座运动以及吊索受力进行分析研究,旨在找出其中的一些特点。整个下放过程采用的是最常用的直接下放法,将整个下放过程根据基座下放深度分成六个阶段,每个阶段又分为待命工况和操作工况,两者的环境参数有所不同。通过大量的数据计算得到各个阶段吊索的最大受力和基座重心的最大偏移量,据此得出一些实用结论,整个数值模拟采用OrcaFlex软件进行时域分析,所得结果可为今后相关研究提供参考。
This article mainly focus on the motion of the manifold in deepwater lowering operation. The whole lowering process is divided into 6 stage which depends on the depth of the manifold, every stage contains working condition and standby condition. In this article, a lot of analysis has been done to illustrate the maximum tension of the sling and also the maximum offset of the manifold, some conclusion has been summarized. The time history numerical simulation is done by OrcaFlex software and the data will be helpful for the other researchers.
