摘　　要：随着海洋石油工业向深水及超深水领域的发展,传统悬链式锚泊线的使用受到限制。论文在传统悬链式锚泊线的基础上串联浮筒,优化设计出一种新型的串联浮筒悬链式锚泊线。首先,介绍新型串联浮筒锚泊线的优化设计过程;其次,在时域范围内建立串联浮筒锚泊线的动力分析模型,利用耗散能量法计算锚泊线阻尼;最后,结合算例分析串联浮筒对锚泊线阻尼特性的影响,并对浮筒大小和位置的影响进行参数化分析。研究结果对深水浮式平台锚泊系统的设计提供了一种新的参考选择。Application of traditional catenary mooring is limited with the development of offshore oil and gas fields towards deep water and ultra-deep water. A new type of catenary mooring line with a submerged buoy is proposed. Optimal design procedure is introduced, and a dynamical model of the mooring line with buoy is established in time domain. The energy dissipation method is applied to calculate mooring-induced damping. Impact of buoy on the mooring line damping is analyzed through a numerical example. Moreover, sensitivity analysis on the parameters of buoy size and location is carried out. The results would provide reference to engineering design of the mooring system of floating platform.
