摘要
针对浅水环境下典型外单点系泊系统的结构特性,建立悬链锚腿式系泊系统(Catenary Anchor Leg Mooring System,CALM)、单锚摇臂式系统(Sal Yoke System,SYS)、水上软刚臂式系泊系统(Soft Yoke Mooring System,SYMS)3种单点系泊系统和浮式生产储卸油装置(Floating Production Storage and Offloading,FPSO)船体的多体水动力模型。基于船体与外单点系泊系统的时域耦合分析算法,综合考虑风、浪、流载荷的影响,计算得到FPSO的运动响应和外单点系泊系统所受载荷,统计和比较各单点系统的系泊性能和特点,为浅水环境下外单点系泊系统的设计研究提供理论依据。
For the structural characteristic of classic single point mooring systems under shallow-water environment,a multi-body hydrodynamic model of Floating Production Storage and Offloading(FPSO)hull and Single Point Mooring Systems(SPM)such as Catenary Anchor Leg Mooring system(CALM),Sal Yoke System(SYS),and Soft Yoke Mooring System(SYMS)is proposed.Based on the coupled analysis method in time domain,by considering the effects of wind,current and wave loads,the motion performance of FPSO and mooring forces of various SPMs are calculated and analyzed,in order to provide the reference to the design of SPM under shallow-water environment.
