| 摘 要： | 在时域范围内建立深水锚泊线串联浮筒系统的动力分析模型,考虑锚泊线和海床之间的接触作用,基于Morison公式计算锚泊线的惯性力和拖曳力荷载,并利用单根锚泊线由于上部浮体运动而吸收的能量来计算锚泊阻尼。分析串联浮筒系统对锚泊线张力和阻尼的影响特征,进而对串联浮筒的大小和所处位置进行参数敏感性分析。该结果对深水浮式平台锚泊系统设计中如何有效地减小锚泊张力具有实际意义。

| Abstract: | A dynamic analysis model of deep water mooring lines with buoys system is established in time domain. The contact interaction between mooring line and seabed is considered, the fluid drag force and inertia force on the mooring line are calculated according to the Morison formula. The dissipated energy by a mooring line from the floating platform as a result of its oscillation is applied to calculate the mooring-induced damping. Analysis on the impact that buoys system has on the mooring line tension and damping on which they are attached. Moreover, the parameter sensitivity analysis of buoys size and location are executed. The results above may be helpful for reducing the tension in the design of mooring system for deep water floating platform. |
