To provide an automatic navigation single-screw twin-rudder vessel provided with an emergency control function capable of escaping from an abnormal navigation state by giving a command from an original navigator of a vessel including the function of automatic navigation when the vessel becomes an abnormal navigation state.SOLUTION: An automatic navigation single-screw twin-rudder vessel includes an automatic controller 201 for controlling the direction of hull motion by a combination of two pieces of high lift rudders 102 and 103 and an emergency controller 203 for controlling the direction of the hull motion by combining rudder angles of the two pieces of high lift rudders 102 and 103 independently from the automatic controller 201. The automatic controller 201 includes a navigation command receiving unit 265 for receiving a navigation command by radio communication and an automatic navigation steering unit 253 for carrying out steering by automatic navigation on receiving the steering command, and the emergency controller 203 includes an emergency command receiving unit 301 for receiving an emergency command by radio communication, an emergency power source shutting off unit 302 for stopping power supply to the automatic controller 201 on receiving the emergency command, and an emergency steering unit 303 for carrying out hovering steering having the hull remain in place on receiving the emergency command.SELECTED DRAWING: Figure 1

    【課題】自動航行を行う機能を有する船舶が異常操船状態となったときに、船舶の本来の操船者から指令を与えることで異常操船状態から脱することができる緊急制御機能を備えた自動航行一軸二舵船を提供する。【解決手段】2枚の高揚力舵102、103の舵角を組み合わせて船体運動の方向を制御する自動制御装置201と、自動制御装置201から独立して2枚の高揚力舵102,103の舵角を組み合わせて船体運動の方向を制御する緊急制御装置203を備え、自動制御装置201は、無線通信により操船指令を受け取る操船指令受信部265と、操船指令を受けて自動航行の操船を行う自動航行操船部253を有し、緊急制御装置203は、無線通信により緊急指令を受け取る緊急指令受信部301と、緊急指令を受けて自動制御装置201への給電を停止する緊急電源遮断部302と、緊急指令を受けて船体をその場に留まらせるホバリング操船を行う緊急操船部303を有する。【選択図】図1
