Abstract: The reliability of the mooring system is the key performance to ensuring the safety of fishing vessels when they are moored in the harbor to avoid the wind. It is of great significance to improve the safety of fishing vessels by analyzing the force on mooring lines in a typhoon and checking the reliability of the mooring system. Taking the 42 m trawler, which is common and typical in the Shengsi sea area of Zhejiang Province, as a representative ship type, physical model tests were carried out on two types of mooring systems, namely, "two boats straight line mooring" and "two boat splay line mooring". Wind, wave, and current conditions in the harbor were simulated. Through combined tests on different conditions, the various rules of cable tension with wave height, wind speed, and current conditions were obtained, the stress conditions of the two types of mooring were compared, and its security is verified. The results show that under the set typhoon conditions, the two mooring methods can meet the requirements for the safety of fishing boat mooring, and the "two boats splay line mooring" scheme is safer and more stable than the "two boat along line mooring" scheme. The research results can provide support and reference for the design of berthing mode and mooring scheme of fishing vessels in the port.

摘要: 渔船港内停泊避风时,系泊系统的可靠性是保证渔船安全的关键性能,分析台风情况下系泊缆的受力,检验系泊系统的可靠程度,对提高渔船避风安全性有重要的意义。以浙江省嵊泗海域较为常见和典型的42 m拖网渔船为代表船型,对“双船顺缆系泊”和“双船八字缆系泊”2种系泊系统分别进行了物理模型试验,模拟了港内的风浪流条件,并通过对不同条件进行组合试验,获得了缆绳张力随波高、风速、水流情况的变化规律,对两种系泊方式的受力情况进行了对比,并对其安全性进行了验证。 结果显示,在设定的台风工况下,两种系泊方式均能满足渔船系泊安全性,且“双船八字缆系泊”方案相较“双船顺缆系泊”方案更安全稳定。该研究成果可为港内渔船停泊方式和系泊方案设计提供了支持和参考。
