Zusammenfassung:To provide a technique for suppressing fluctuation in an engine load and to improve fuel consumption of a marine vessel.SOLUTION: A control device 23 comprises: a prediction part 27 which predicts a load fluctuation amount of an engine 19 due to disturbance at a prescribed timing; a steering angle control part 29 which controls a steering angle according to a target steering angle value; and a fuel control part 33 which controls a fuel supply amount by increasing the fuel supply amount to the engine 19 when a load of the engine 19 increases due to the disturbance load fluctuation amount and the steering angle load fluctuation amount, and decreasing the fuel supply amount to the engine 19 when the load of the engine 19 decreases due to the disturbance load fluctuation amount and the steering angle load fluctuation amount on the basis of the disturbance load fluctuation amount predicted by the prediction part 27, the steering angle load fluctuation amount and a target rotation speed.SELECTED DRAWING: Figure 1 【課題】エンジンの負荷の変動を抑制して船舶の燃費を向上させる技術を提案する。【解決手段】上記課題を解決するために、制御装置23は、所定タイミングでの外乱によるエンジン19の負荷変動量を予測する予測部と27、目標舵角値に従って舵角を制御する舵角制御部29と、予測部27が予測した外乱負荷変動量、舵角負荷変動量、及び目標回転数に基づいて、エンジン19の負荷が外乱負荷変動量及び舵角負荷変動量により増加する場合にはエンジン19への燃料供給量を増加させ、エンジン19の負荷が外乱負荷変動量及び舵角負荷変動量により減少する場合にはエンジン19への燃料供給量を減少させて燃料供給量を制御する燃料制御部33とを備える。【選択図】図1
