深水柔性立管的缓波型布置及参数敏感性分析

针对某深水柔性立管进行缓波型布置设计，确定浮力块的尺寸和位置，顶部悬挂角和管内流体密度等主要布置参数。运用集中质量法建立分析模型，并在此基础上研究柔性立管的初始形状、曲率和张力对不同总体布置参数的敏感性及变化规律，得到一些有用的结论可作为柔性立管总体布置设计的参考。

Lazy Wave Configuration and Parameter Sensitivitiy Analysis of Deepwater Flexible Riser

This paper presented a solution of Lazy Wave configuration key parameters,including the sizes and position of buoyancy modules,top hang off angle and inside fluid density. The flexible riser model was built to perform parameter sensitivity analysis on initial shape,curvature and tension of the flexible riser with lumped mass method.The variation rules for key mechanical performances of flexible riser under different conditions were found and some useful conclusions were generated,which may provide a referen...
