SHIP PROPULSION PERFORMANCE PREDICTION DEVICE AND METHOD, AND SHIP OPERATION ASSIST SYSTEM

摘要

A ship propulsion performance prediction device (10) is provided with: a theoretical propulsion performance computation unit (20) that computes, using a physical model of a propulsion system of a ship of concern, theoretical propulsion performance with respect to a desired operational condition; and a correction unit (30) that corrects the theoretical propulsion performance, using a flat-water correction term and a disturbance correction term stored in a correction term database (40). The flat-water correction term and the disturbance correction term stored in the correction term database (40) are derived from operational results data by a correction term derivation unit (50). The correction term derivation unit (50) is provided with a flat-water correction term derivation unit (53) for deriving the flat-water correction term using the operational results data and the like under flat-water condition, and a disturbance correction term derivation unit (54) that computes, using the operational results data and the like corresponding to each disturbance condition, a disturbance correction term corresponding to the disturbance condition. In this way, the prediction accuracy of ship propulsion performance in an actual ocean area can be increased.
