Ship monitoring system, ship monitoring method, and information processing device

Abstract

The present disclosure provides a ship monitoring system capable of appropriately evaluating risks of collisions for a plurality of other ships which constitute a convoy. The ship monitoring system includes a first data generator, a second data generator, and processing circuitry. The first data generator generates first ship data indicative of a position and a velocity of a first ship. The second data generator generates a plurality of second ship data indicative of positions and velocities of a plurality of second ships. The processing circuitry calculates a risk value indicative of a risk of a collision between the first ship and each of the plurality of second ships based on the first ship data and the plurality of second ship data. The processing circuitry determines whether the plurality of second ships are a convoy based on the plurality of second ship data. The processing circuitry selects a representative value from the risk values calculated for the plurality of second ships determined to be the convoy.
