  • Non-transitory computer readable storage medium containing program instructions for causing a computer to execute steps for an evaluation program of ship propulsive performance in actual seas
    Patent number: 11981406
    Abstract: Objects of the present invention are provide as evaluation method of ship propulsive performance in actual seas, an evaluation program of ship propulsive performance in actual seas and an evaluation. system of ship propulsive performance in actual seas capable of precisely evaluating ship propulsive performance in actual seas on the same scale also before the ship sails for example. As solving means of the objects, a standard sailing model 2 of the ship in actual seas is set, a sailing condition of the ship and a ship condition of the ship are input to the standard sailing model 2, the standard sailing model 2 into which the sailing condition and the ship condition are input and the ship condition are applied to a previously verified calculating method 1 of ship performance is actual seas, and ship propulsive performance in actual seas is evaluated.
