PROBLEM TO BE SOLVED: To improve an estimation accuracy of propulsion performance of a ship on an actual sea area.SOLUTION: A ship propulsion performance estimation device 10 includes a theoretical propulsion performance calculation part 20 which calculates theoretical propulsion performance with respect to desirable navigation conditions by using a physical model of a propulsion system of an objective ship, and a correction part 30 which corrects the theoretical propulsion performance by using an ordinary water correction term and a disturbance correction term stored on a correction term data base 40. The ordinary water correction term and the disturbance correction term stored on the correction term data base 40 are derived from navigation actual data by a correction term derivation part 50. The correction term derivation part 50 includes an ordinary water correction term derivation part 53 which derives the ordinary water correction term by using navigation actual data or the like under ordinary conditions and a disturbance correction term derivation part 54 which calculates a disturbance correction term corresponding to disturbance conditions by using the navigation actual data or the like corresponding to respective disturbance conditions.SELECTED DRAWING: Figure 2

    【課題】実海域における船舶の推進性能の予測精度を向上させることを目的とする。【解決手段】船舶の推進性能予測装置10は、対象船舶の推進系の物理モデルを用いて所望の運航条件に対する論推進性能を演算する理論推進性能演算部20と、補正項データベース40に格納された平水補正項及び外乱補正項を用いて、理論推進性能を補正する補正部30とを備えている。補正項データベース40に格納される平水補正項及び外乱補正項については、補正項導出部50によって運航実績データから導出される。補正項導出部50は、平水条件下の運航実績データ等を用いて平水補正項を導出する平水補正項導出部53と、それぞれの外乱条件に対応する運航実績データ等を用いて当該外乱条件に対応する外乱補正項を演算する外乱補正項導出部54とを備える。【選択図】図2
