基于穿越角度的船舶航道间隙计算方法

为了防控船舶横越港口以及航道时候的船舶碰撞风险,对船舶穿越间隙进行研究。通过建立模型与研究计算方法,改变穿越角度,使穿越间隙的出现时间发生改变。将实测数据统计整理,建立了某港口水道的通行船舶数据,并对模型进行了验证,发现船舶在不同穿越角度下出现的穿越间隙也会不同,证明船舶可以在不同穿越角度的基础上通过选择有利的穿越时机达到合适的穿越间隙穿越水道,来降低船舶的碰撞风险。

Research on Calculation Method of Ship Crossing Clearance based on Crossing Angle

: In order to prevent and control the ship collision risk when the ship crosses the port and the navigation channel, the ship crossing gap is studied. By establishing a model and studying the calculation method, the crossing angle is changed, so that the occurrence time of the crossing gap changes. The measured data is statistically sorted, the passing ship data of a port waterway is established and the model is verified. It is found that the crossing gaps appearing at different crossing angles of the ship will be different, which proves that the ship can choose favorablely on the basis of different crossing angles. The crossing time to reach the appropriate crossing clearance through the waterway can reduce the risk of collision of the ship.
