Abstract:
1. A method of preventing a collision between vessels, comprising: collecting information about a position of a reference vessel using a mobile terminal on the reference vessel; receiving information about a counterpart vessel from a user on the reference vessel via the mobile terminal; calculating an expected collision route based on the information about the position of the reference vessel and the information about the counterpart vessel; calculating escape routes capable of preventing a collision between the vessels if a possibility of a collision corresponding to the expected collision route is above a set value; providing the escape routes via mobile terminals on the vessels and comparing changes in actually measured positions of the vessels with the escape routes; managing navigation of the vessels based on results of the comparison between the changes in the actually measured positions of the vessels and the escape routes; determining whether at least one of the vessels provided with the escape route is a give-way vessel or a stand-on vessel if a change in route is not approved by the at least one of the vessels; and calculating an alternative escape route, replacing the escape route, based on results of the determination.
