| 摘 要： | 在给出悬链线和缓波形理论公式的基础上，对某一深海脐带缆进行悬链线布局和缓波形布局两种不同布局形式的选型设计研究，计算得到脐带缆在两种布局下的静态和动态响应，及其有效张力和弯曲曲率的分布特性。结果显示有效张力的最大值都发生在悬链线布局和缓波形布局的顶部悬挂点，而弯曲曲率的最大值发生在悬链线布局的触地点和缓波形布局的上升段末端；缓波形布局在减小有效张力的同时还减小顶部浮体和波浪运动对脐带缆的动态干扰。

| Abstract: | The Free Hanging Catenary shape and Lazy-Wave shape are designed for an deepwater umbilical based on the theoretical equations of the two kinds of shapes. The Static and dynamic responses of this umbilical under both shapes are calculated, as well as the distribution characteristics of effect tension and curvature. The results show that the maximum effect tensions all happen at the top hang points of the Free Hanging Catenary shape and Lazy-Wave shape, but the maximum curvatures happen at the TDP of the Free Hanging Catenary shape and the lift section’s endpoint of the Lazy-Wave shape. In addition，the Lazy-Wave shape can reduce the effect tension and the dynamic interference to the umbilical caused by the motion of the top float and the wave. |
