Abstract
The present disclosure provides a ship monitoring system capable of improving legibility of an OZT. 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 second ship data indicative of a position and a velocity of a second ship. The processing circuitry calculates a risk value indicative of a risk of a collision between the first ship and the second ship based on the first ship data and the second ship data, for each point on an estimated course of the second ship, when the first ship is assumed to change a course and reach the point. The processing circuitry specifies a range where two or more continuous points have the risk values above a threshold. The processing circuitry displays a risk range including the range where the two or more continuous points have the risk values above the threshold.
