船舶旁靠时缆绳受力分析

Stress Analysis of Mooring Cable for Ship Berthing alongside

船舶系缆力是评价系泊安全的一个重要指标,每条缆绳受力的大小和各缆绳受力是否均匀都会影响到船舶系缆系统的稳定性。本文通过对“仁建”轮所停靠码头的介绍,分析了风载荷、流载荷、缆绳种类和带缆方式等对该轮轮缆绳受力的影响。基于相关公式与实测船舶的缆绳角度,计算每根缆绳的受力,以避免缆绳超负荷工作,造成断缆。以该轮的带缆方式为例,估算可以承受的最大风力,并提出了增强泊稳性的方法,提高船舶靠泊的安全性和稳定性。

The ship mooring force is an important factor inthe evaluation of mooring safety.How much force acts on each of mooring cables and whether all the cables are evenly stressed affects the stability of ship mooring system.This paper analyzes the influence of wind load,current load,cable type and mooring pattern on the forces acting on the mooring cables of the ship"Renjian 9".Based on the relevant formula and the measured mooring cable angles,the stress of each cable is calculated so as to avoid cable breakage by overload.Taking the mooring pattern of this ship as an example,the maximum wind force that the cable can bear is estimated,together with the method to enhance the berthing stability being proposed,so that the safety and stability of the ship berthing can be improved.
