舾装船舶吃水浅、受风面积大，在系靠泊过程中易出现缆绳断裂的情况。基于舾装船舶船体-系泊系统耦合动力分析模型，研究缆绳渐进失效动态演化机制，分析系泊缆数量和系泊布置方案与断缆情况下船舶动力响应的关系。结果表明：恶劣环境下，断缆后船舶横荡、纵荡以及艏摇运动响应幅度显著增大，局部缆绳张力超出最小破断力，易发生渐进式失效；增加系泊缆绳数量可有效降低断缆影响，系泊缆数量为30根时，系泊系统不均匀系数最小；陆侧增设两根锚链（分别与船舶纵轴线成45°和135°夹角）可以维持断缆情况下系泊系统的稳定。研究成果可为恶劣海况下船舶系泊系统的失效模式分析和安全评估提供参考。
Outfitting ships are characterized by shallow drafts and large wind-exposed areas, making them susceptible to cable breakage during mooring operations. A coupled dynamic analysis model of the hull-mooring system for outfitting ships is employed to investigate the dynamic evolution mechanism of progressive cable failure and to analyze the relationship between the number of mooring cables, mooring arrangement schemes, and the ship’s dynamic response under cable breakage. The results indicate that under harsh conditions, the amplitudes of sway, surge, and yaw motions are significantly increased after cable breakage, with local cable tensions exceeding the minimum breaking strength. This leads to progressive failure. The impact of cable breakage is effectively reduced by increasing the number of mooring cables. When the number of mooring cables reaches 30, the non-uniformity coefficient of the mooring system is minimized. Additionally, by adding two anchor chains on the shore side (oriented at 45° and 135° to the ship’s longitudinal axis), the stability of the mooring system is maintained in the event of cable breakage. The research findings provide references for failure mode analysis and safety assessment of ship mooring systems under severe sea conditions.
