DESCRIZIONE
A system and method for managing navigation plan of a marine vessel on a potential collision course with one or more other marine vessels is provided. The system and method comprises generating identification data, by the identification unit, indicative of at least manoeuvrability of the marine vessel. The system and method also comprises calculating, by the computing unit, priority factors of all the marine vessels involved in the potential collision course based on corresponding identification data thereof, then comparing the calculated priority factors of all the marine vessels, and then determining a required change in the navigation plan of the marine vessel based on the comparison, such that the marine vessel(s) with a lower calculated priority factor out of all the marine vessels alter the navigation plan(s) thereof to give way to the marine vessel(s) with a comparatively higher calculated priority factor.
