Abstract

The invention discloses a ship navigation risk early warning method and system based on icebreaker escorting and a medium, and can be applied to the technical field of ships. According to the invention, the ice breaker risk field potential energy and the sea ice risk field potential energy corresponding to the current following ship are determined by combining the following distance and the navigation speed with the pre-constructed ice breaker risk field model and the sea ice wind field danger field model; then, according to the north pole sailing ship following model, the minimum safe following distance of the current following ship and the icebreaker risk field model, the acceptable collision risk potential energy of the current following ship is determined; according to the sea ice movement speed, the channel width, the maximum sea ice concentration of the current following ship and the sea ice wind field danger field model, the acceptable ice trapping risk potential energy of the current following ship is determined; and carrying out risk early warning on the current following ship according to the icebreaker risk field potential energy, the sea ice risk field potential energy, the acceptable collision risk potential energy and the acceptable ice trapping risk potential energy, thereby reducing the navigation risk in the ship navigation process.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to a ship navigation risk warning method, system and medium based on icebreaker escort. Background technique [0002] With global warming and the gradual melting of sea ice in the Arctic, the development and utilization of the Arctic shipping lanes have received more and more attention. The Arctic route greatly shortens the shipping distance between Europe and Asia, and can also reduce the fuel consumption of ships and save costs. Icebreaker escort is a typical operation mode for ships sailing in ice areas. In order to ensure the safe navigation of the fleet, a certain safe distance must be maintained between ships. At present, the determination of the following distance of ships under icebreaker escort mainly depends on the experience of pilots. . If the following distance is too short, collision accidents between ships are prone to occur; if the following distance is too large, th...
