基于船行波安全航速的限定

Determination for safe speed based on ship's waves

针对在受限水域中船舶航行时生成的船行波影响周围船舶安全及作业的问题,计算了船舶在不同航速时船行波的波高及其衰减程度,通过模型计算得到不同船行波对其他船舶影响的横摇数值.根据目标船与本船的距离,通过定量分析对周围目标船稳性、横摇幅度的影响,确定本船的安全航行速度及目标船的安全作业区域,对船舶在航道、港口等受限水域安全速度的控制提供理论依据.

Owing to ship waves generated by the vessel sailing in the restrict water may influences rounding ships safety and operations. In the paper, height and attenuation degree of ship waves at different ship's speeds are calculated and rolling parameters affecting other ships in different ship waves are obtained by calculation model. Further, safe sailing speed and operation area are determined according to the distance between target ship and own ship by analyzing the effects of stability and rolling extent ,which provides theory basis for controlling safe speed in the restrict water.
