VTS对船舶搁浅危险预警

Research on Ship Grounding Risk Alerts by VTS

为提高船舶交通管理系统(Vessel Traffic Service,VTS)对船舶搁浅危险预警的有效性,综合应用船舶AIS系统、电子海图和潮汐等信息,根据船舶的大小、运动状态以及相对位置,设置动态的搁浅危险判定条件,根据引入的形成搁浅紧迫局面的时间(Time of Close-Quarters Situation of Ground,TCQG)值来判断船舶搁浅危险的紧迫程度,以指导有关人员及时向存在搁浅危险的船舶发出危险预警信息,提醒船舶及时采取合适的避浅行动.经模拟器验证该预警方法切实可行,对船舶搁浅危险有预警作用.

To improve the effectiveness of ship grounding alert in VTS waters,this paper combines the application of ship AIS,ECDIS and tide information,etc. According to ships of diffident sizes,diffident states of motion and relative positions,it sets dynamic determination conditions of grounding risks. According to the introduction of Time of Close-Quarters Situation of Ground（ TCQG）,it can determine the degree of urgency of the danger of grounding for a vessel. Through this method,VTS duty officer can send out timely warning information to the ship in danger and let the ship take appropriate action to avoid grounding. This method can reflect the actual situation of the ship to avoid the danger of grounding through simulating and verifying by a simulator,and play a better role in ship grounding risk alerts by VTS.
