采用时域耦合动力分析方法，并考虑系泊缆的非线性动态特性和平台与系泊缆之间的相互作用，分析张紧式系泊系统的系泊缆流体动力系数、系泊缆张力倾角、系泊缆布置角度、系泊缆数目等对平台系泊性能的影响.结果表明，不同的系泊参数对系泊系统性能均有不同程度的影响，合理选取系泊参数能有效控制系统的运动响应和系泊缆动力效应.
Abstract
In order to investigate the effects of the parameters of taut-wire mooring systems on the performance of semi-submersible platforms, the method of time-domain coupled-dynamic analysis is used, and the nonlinear dynamic characteristics of mooring lines and the interaction of platform as well as mooring lines are considered .Results show that the different parameters, such as hydrodynamic coefficients of mooring line, dip angle of tension, arrangement angle of mooring line as well as number of mooring lines have different effects on the performance of the mooring system. The platform motion responses and mooring line dynamic effect can be controlled effectively if the parameters are selected reasonablely.
