本文以孟加拉国海域某悬链式单点系泊装置(Catenary Anchor Leg Mooring，CALM)装置为研究对象，研究了其在不同风浪流条件下的水动力响应和运动状态。采用理论研究与数值模拟的方法，研究单点系泊装置在有无油轮系泊工况下浮筒的运动响应、锚链受力、水下软管响应及系泊缆受力等情况，进而开展了对比分析并从中总结锚链长度对单点系泊装置稳定性的影响及运动规律。最后通过仿真计算验证了该系统在系泊状态下的稳定性，给出了系泊关键参数和系统稳定性的关系。
In-Position Stability Analysis of Catenary Anchor Leg Mooring
This article takes a CALM system in the waters of Bangladesh as the research object,and studies the hydrodynamic response and motion state of the catenary single-point mooring device under different wind,wave,and current conditions.Furthermore,theoretical research and numerical simulation methods are used to analyze and study the motion response of the buoy,the force on the anchor chain,the response of the underwater hose,and the force on the mooring cable of the single-point mooring device under the conditions of mooring with and without tankers.A large number of comparative analyses are conducted,and the influence of the length of the anchor chain on the stability and motion law of the single-point mooring device are summarized.Finally,the stability of the system when mooring the tanker is verified through simulation calculations,and the relationship between key parameters and system stability is given.
