摘要

为研究港口内船舶停靠过程中收缆方式对停靠安全的影响,应用泰勒级数对船舶系泊缆绳以及港口防撞材进行建模,应用时域响应方法计算船体位移及船舶系缆力.以总长203m的集装箱船为研究对象,考虑低海况与高海况两种环境,计算港口内船舶停靠过程中船舶系缆力与各个自由度下的船体位移,对高海况下不同绞缆方式对船舶系缆力、船体横摇与垂荡的影响进行研究.结果表明:船舶在停靠过程中,船体位移变化范围及系缆力最大值与绞缆机组合运行方式有关,且船舶绞缆方式对系缆力影响显著,失当的绞缆方式将导致系泊缆绳断裂.

Abstract

To find the influence of winch mode on ship docking safety in harbor during docking process, the model for cables and anticollision metals model was built up with Taylor series, and the displacement and mooring forces were calculated by using time domain response method. Taking a 203 m container ship as object, the cable forces for ship in the docking progress and displacement in each degree of freedom were calculated for normal and severe sea state. The influence of different winch mode on mooring force values, hull rolling values and heaving values for a ship were studied in severe sea state. Results show that range of displacement variation and maximum mooring force relate to combination operation mode of warping winch, and winch mode has remarkable effects on mooring force, and the wrong winch mode will result in cables failure. Above results can provide a reference for studying docking safety and port disaster prevention.
