To provide an autonomous navigation ship capable of suppressing deterioration of a battery and delay of arrival time at a destination.SOLUTION: An autonomous navigation ship according to an embodiment includes a hull, a vertical sail, a wing sail, an electric drive device, a battery, an information collection device, a control device, a positioning device, and an autonomous navigation device. The autonomous navigation device predicts, on the basis of weather information and ocean information, a remaining amount of the battery at a time of arrival at a destination after navigation with the wing sail driven, and, upon determining that the remaining amount of the battery will be equal to or greater than a predetermined remaining amount, controls the electric drive device to maximize an output of the electric drive device.SELECTED DRAWING: Figure 1
【課題】バッテリの劣化、および、目的地への到着時刻の遅延を抑制することができる自律航行船舶を提供する。【解決手段】実施形態に係る自律航行船舶は、船体と、縦帆と、翼帆と、電動駆動装置と、バッテリと、情報収集装置と、制御装置と、測位装置と、自律航行装置とを備える。自律航行装置は、翼帆を駆動させての航行により目的地へ到着した時点のバッテリの残量を気象情報および海洋情報に基づいて予測し、バッテリの残量が所定の残量以上になると判定した場合に、電動駆動装置の出力を最大にするように電動駆動装置を制御する。【選択図】図1
