Abstract: A ship-collision prevention system and method for preventing a collision between ships at sea including a ship-collision avoidance guiding system using a time series graphic display, and guiding system displays, in a time series graph, depicting changes in relative distance according to time with respect to respective ships and obstacles on the basis of information provided from an electronic chart display and information system (ECDIS) and a radar system, wherein, whether other ships are on portside or starboard is displayed on the basis of radar information, and a notification through an alarm or the like if a distance to a specific ship has matched a predetermined threshold value or less, and effectively preventing a collision between ships at sea, and simultaneously, enabling a simulation for a crossing event and avoidance by inputting a random value.

Abstract: The present invention relates to a ship-collision prevention system and method for preventing a collision between a ship at sea and another ship, and according to the present invention, provided is a ship-collision avoidance guiding system using a time series graphic display, and in order to solve problems of a conventional electronic chart display and information system (ECDIS) and navigation systems using the same, which have a disadvantage of a complex and unintuitive screen display because of a simple enumeration of various pieces of information on a screen, the guiding system displays, in a time series graph, changes in relative distance according to time with respect to respective ships and obstacles on the basis of information provided from the ECDIS and a radar system, wherein, in a case of ships, whether the respective ships are on portside or starboard is displayed on the basis of radar information, and if a distance to a specific ship has a predetermined threshold value or less, the guiding system
