Abstract
A non-transitory computer-readable recording medium stores a program that causes a computer to execute a process. The process includes extracting a sailing log of a ship in a sea area with a sailing route existing therein, the sea area being such that a distance between two ships of the ship and another ship is less than a predetermined value and at least one of the two ships has a ship track deviating from the sailing route; and evaluating risks at a plurality of points that are included in the sea area, based on the extracted sailing log.
Claims7
A non-transitory computer-readable recording medium having stored therein a program that causes a computer to execute a process comprising:
- extracting a sailing log of a ship in a sea area with a sailing route existing therein, the sea area being such that a distance of closest approach between two ships in a case where the two ships maintain courses and speeds thereof is less than a predetermined value and at least one of the two ships has a ship track deviating from the sailing route;
- evaluating risks at a point of maneuvering behavior for collision avoidance that are included in the sea area, based on the extracted sailing log;
- and
- outputting the point of maneuvering behavior for collision avoidance.
An evaluation method comprising:
- extracting, by a processor, a sailing log of a ship in a sea area with a sailing route existing therein, the sea area being such that a distance of closest approach between two ships in a case where the two ships maintain courses and speeds thereof is less than a predetermined value and at least one of the two ships has a ship track deviating from the sailing route;
- evaluating, by the processor, risks at a point of maneuvering behavior for collision avoidance that are included in the sea area, based on the extracted sailing log;
- and
- outputting the point of maneuvering behavior for collision avoidance.
An evaluation device comprising:
- a processor that executes a process, the process comprising:
- extracting a sailing log of a ship in a sea area with a sailing route existing therein, the sea area being such that a distance of closest approach between two ships in a case where the two ships maintain courses and speeds thereof is less than a predetermined value and at least one of the two ships has a ship track deviating from the sailing route;
- evaluating risks at a point of maneuvering behavior for collision avoidance that are included in the sea area, based on the extracted sailing log;
- and
- outputting the point of maneuvering behavior for collision avoidance.
