极地钻井船因搭载众多钻探设备导致上层建筑迎风面积大，故针对其台风天气下存在系泊风险的问题，本文通过物理模型试验研究其在台风下的运动响应。以一艘211 m长的极地钻井船为研究对象，按1∶40缩尺比构造模型，测量其在不同风、浪、流组合工况下的六自由度运动响应和系缆力变化。结果表明，风和流均对系泊系统存在较大影响，其中90°方向离岸风作用下的船舶横摇达到最大值6.68°，横荡和艏摇影响同样较为显著，同时受到尾流作用，艉横缆和艏倒缆呈现持续大于1000 kN高张力状态，通过优化重构系缆拓扑布局可显著减小系泊运动幅度和缆绳缆力差，改善系泊整体的安全性。本研究为极地钻井船系泊设计提供了具体方案和优化依据，对高风压船舶的系泊安全具有普适性参考价值。
Due to the large windward area of the superstructure caused by numerous drilling equipment onboard, polar drilling vessels face significant mooring risks during typhoons. To address this issue, this study investigates the vessel’s motion response under typhoon conditions through physical model tests. A 211-meter-long polar drilling vessel was selected as the research object, and a 1∶40 scale model was constructed to measure its six-degree-of-freedom motion responses and mooring line forces under combined wind, wave, and current conditions.The results indicate that both wind and current substantially influence the mooring system. Under offshore winds from a 90° direction, the vessel’s maximum roll angle reaches 6.68°, with significant sway and yaw motions. Additionally, due to wake effects, the stern breast line and head spring line sustain high tensions exceeding 1000 kN. By optimizing the topological layout of the mooring lines, the mooring motion amplitude and line tension differentials can be significantly reduced, thereby improving overall mooring safety.This study provides a specific design scheme and optimization basis for the mooring of polar drilling vessels, offering universal reference value for the mooring safety of high-windage ships.
