本文对某采用缓波形布局的深水脐带缆进行静态分析,得到了脐带缆的整体结构响应,包括脐带缆初始线形、有效张力和弯曲曲率的分布特性。同时对脐带缆缓波形布局下的总体布局参数进行了参数敏感性分析,得到了浮子段长度、浮力因子、浮子段起始位置及顶部悬挂角对脐带缆结构响应的影响。这些研究结果可以为深水脐带缆的缓波形布局设计提供参考。
Abstract
In this paper, the structure performance of the umbilical was obtained, including the configuration, effective tension and curvature by the static analysis of a Lazy-wave deepwater umbilical. Meanwhile, the sensitivity analysis of the general layout parameters, including the length of the buoyancy catenary, buoyancy factor, starting location of the buoyancy catenary and top hang-off angle, was performed and the influence of the general layout parameters on the structure performance of the umbilical was generated. These research results may provide a reference for the Lazy-wave configuration design of the deepwater umbilical.
