单点系泊油轮运动响应分析及运动控制

Motion response analysis and motion control of single point mooring oil tankers

基于数值模拟,对单点系泊系统动力响应进行研究,探究单点系泊系统在波流不同向和特殊作业工况下油轮的运动规律和系泊力的影响因素,并给出船体控制的方法。研究结果表明,波流夹角、波浪和流速会对船体运动和系泊力大小产生显著影响;在船尾处0°方向和船侧135°方向施加拉力,会降低船体运动幅值及系泊缆绳拉力。最后给出了该系泊系统的极限作业海况条件。

This article is based on numerical simulation to study the dynamic response of a single point mooring system.It explores the motion law of oil tankers and the influencing factors of mooring force under the combined action of wind,waves,and currents in a single point mooring system,and provides a method for ship control.The research results indicate that the angle between waves and currents,waves,and flow velocity have a significant impact on ship motion and mooring force;Applying tension in the 0° direction at the stern and 135° direction at the side of the ship will reduce the amplitude of ship motion and mooring line tension.Finally,the ultimate operating sea conditions for the mooring system were provided.
