MANEUVERING CONTROL METHOD AND MANEUVERING CONTROL SYSTEM

摘要

A short-term planned route (B) from a start position that is a ship position at a first time up to an end position that is the ship position at a second time is designed based on a planned route (A), an estimated encounter marine phenomenon information, operation performance information measured on a ship, and a hull motion model of the ship, the planned route (A) being based on meteorological and marine phenomena prediction information and performance information of the ship, the estimated encounter marine phenomenon information being measured on the ship based on actually encountered marine phenomenon information. The short-term planned route (B) makes a first evaluation function (J) optimal, the first evaluation function (J) containing: an index indicating an influence of a fluctuation portion between a planned position that is a ship position planned at the second time on the planned route (A) and the end position; a fuel consumption index when the ship sails along the short-term planned route (B); and a safety index when the ship sails along the short-term planned route (B).
