COURSE GUIDANCE METHOD FOR EFFICIENT SAILING OF SHIP

Disclosed herein is a course guidance method for the efficient sailing of a ship. The course guidance method for the efficient sailing of a ship is performed by a ship's course guidance system, and may include: a per-ship location information extraction step of extracting location information for each ship from collected Auto Identification System (AIS) data; a ship location plotting step of plotting the location of the ship based on the location information on an electronic navigational chart; a clustering step of clustering points located within a predetermined area among a plurality of points plotted on the electronic navigational chart; a course network generation step of generating ship course networks using the clustered points; and a recommended course acquisition step of acquiring a recommended course for each ship based on the generated ship course networks.
