动态缆整体水动力响应对浮筒布局的敏感性分析

Parameter Sensitivity Analysis of Hydrodynamic Response of Global Configuration on the Distributed Buoy Layout

海洋柔性动态缆广泛地应用于远海风电设备以及深海油气开发中,安装其上的浮筒对柔性动态缆的力学行为有着明显的影响。分布式浮筒作为保持动态缆线型的装备,目前从整体分析和线型设计的角度对浮筒段浮力模块之间分布间距等应用研究较少。引入柔性动态缆整体线型的顺应性能指标,并采用OrcaFlex软件建立了陡波线型的数值模型。通过改变不同浮筒段浮力模块之间的距离等主要布置参数,研究了各参数对柔性动态缆顺应性能的影响,对柔性动态缆线型整体布置设计具有一定的参考价值。

Marine flexible dynamic cable is widely used in offshore wind power equipment and the development of marine oil and gas,on which distributed buoyancy modules have a significant impact.From the point of the global configuration design,there are few studies on the design of the spacing between buoyancy modules.In this paper,the flexibility performance of the global configuration of flexible dynamic cable introduced as an indicator,the numerical model of steep⁃wave is established in Orcaflex software.The sensitive influence on the performance of flexible dynamic cable is investigated by changing the arrangement parameters such as the distance between buoyancy modules of different buoyancy sections.This study provides some useful conclusions and reference value for the global configuration design of the flexible dynamic cable.
