To provide an automatic navigation single-screw twin-rudder vessel evading a crush by keeping a vessel in place when a risk of a crush occurs to the vessel having an automatic navigation function.SOLUTION: An automatic navigation single-screw twin-rudder vessel includes: a controller 201 for controlling a direction of hull movement by combining rudder angles of two pieces of high lift rudders 102, 103; an emergency controller 203 for controlling the direction of hull movement by combining rudder angles of the two pieces of high lift rudders 102, 103 independently of the controller 201; and a vessel radar device 271. The emergency controller 203 has a collision risk determination unit 301 and an emergency vessel steering unit 303. The collision risk determination unit 301 determines whether or not an own vessel will collide another ship based on own vessel information and other vessel information obtained from the vessel radar device 271, and issues an emergency command to the emergency steering unit 303 when determining that the own vessel will collide the other ship. Then, the emergency steering unit 303 carries out hovering maneuver for 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に衝突のリスクが生じた場合に、船舶をその場に留めることで衝突を回避する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制御装置201と、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と、船舶レーダ装置271を備え、緊急制御装置203は、衝突リスク判定部301と緊急操船部303を有し、衝突リスク判定部301は、船舶レーダ装置271から得る自船情報と他船情報に基づいて自船が他船に衝突するか否かを判断し、衝突すると判断した場合に緊急指令を緊急操船部303に指令し、緊急操船部303は、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。【選択図】図1
