  • Publication number: 20240109626
    Abstract: A ship monitoring system makes it easier to grasp a heading of another ship, and includes a first data generating part, a second data generating part, and processing circuitry. The first data generating part generates first ship data indicative of a position and a velocity of a first ship. The second data generating part 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 the first ship and the second ship colliding each other, for each point on an estimated course of the second ship, based on the first ship data and the second ship data, when assuming that the first ship changes the course and reaches the point. The processing circuitry displays a risk area indicative of a heading of the second ship at the point where the risk value is more than a threshold.

    Abstract: A ship maneuver supporting device capable of displaying a collision risk zone which matches navigation feel of a ship operator with reduced calculation load, is provided. The ship maneuver supporting device 1 includes processing circuitry (11, 21, 31, 41). The processing circuitry calculates a collision risk value for determining whether a collision risk zone that is a zone where a possibility of a collision between a first ship and a second ship will occur in the future is high is to be displayed, based on a separating distance between the position of the second ship estimated at a plurality of future time points and the position of the first ship estimated corresponding thereto, in consideration of a physical size of at least one of the first ship and the second ship. Further, the processing circuitry generate display data for displaying the collision risk zone at the estimated position of the second ship, based on the determination using the collision risk value.
