波浪周期对系泊船运动量及系泊力的影响研究

Influence of Wave Period on Mooring Motion and Force of a Ship

本研究依托工程实例,运用OPTIMOOR系泊软件,探究波浪周期对系泊船运动量及系泊力的影响规律,结果表明:当波浪周期与船舶自振周期接近时,船舶运动幅度大幅增加,船舶系泊力急剧增大,但船舶各部位系泊索变化规律不同;船舶各种运动对波浪周期、波浪来向的敏感度不尽相同。针对上述研究结果,对船舶系泊系统提出了优化建议。

An engineering practice has been analyzed to explore the influence of wave period on the mooring motion and force of a ship by using OPTIMOOR software. The research results show the increasing of ship movement and mooring force to large extent when wave period is close to ship＇s natural vibration period. However, the mooring cables to fix a ship follow different rules of variation. Various motions of a ship reflect different sensitivities against wave period and direction. Finally an optimum suggestion is proposed for the ship mooring system.
