Ship collision risk reduction method, ship collision risk reduction system, and planned route information provision center

摘要

PROBLEM TO BE SOLVED: To reduce a collision risk by generating a plan route for reducing occurrence of facing-each-other between vessels while keeping profitability in route selection.SOLUTION: Latest track information of multiple other vessels, to which the influence of an ocean stream in a passage sea area of a specific vessel is added, is obtained and stored, so as to generate plan route information for enabling a specific vessel to perform efficient navigation with less encounter with other vessels on the basis of the track information. Route selection of a specific vessel 12 is supported by providing the generated plan route information to the specific vessel.SELECTED DRAWING: Figure 1
