Abstract:
[Problem] To provide a seacraft monitoring system which can improve the accuracy of bumper model-based risk assessment. [Solution] A seacraft monitoring system is provided with: a first estimation unit for estimating the location of a first seacraft at respective points in time on the basis of the current location, vessel speed, and course of the first seacraft; a second estimation unit for estimating the location of a second seacraft at each of the points in time on the basis of the current location, vessel speed, and course of the second seacraft; and a bumper region estimation unit for calculating a fluctuation range of the location of the second seacraft at each of the points in time on the basis of a fluctuation range of the vessel speed of the second seacraft, and estimating a bumper region indicating a region where the second seacraft is possibly located on the basis of the fluctuation range.
