Avoiding ship maneuvering method and avoiding ship maneuvering system in congested waters

摘要

An object of the present invention is to quickly perform forced deceleration (braking) without decelerating the main engine while maintaining the original course in a congested sea area, quickly accelerate after releasing the deceleration, and short distance in a short time The ship is evacuated. In a evacuation vessel in a congested sea area, a propulsion propeller arranged at the stern is always arranged in the rear of the propeller while continuing to travel on the target route 502 of the current ship 501 while maintaining forward rotation. A steering angle is given to the pair of left and right high lift rudders 102 and 103 to make the thrust of the propeller wake downstream as the reverse thrust, and the own ship 501 is decelerated against the inertial force in the forward direction of the own ship 501 by the reverse thrust. After the collision with the other ship 401 is avoided and the other ship 401 passes across the course of the own ship 501, the rudder angle of both the high lift rudder 102 and 103 is controlled, and the thrust of the propeller wake is set as the forward thrust. Continue on the intended course. [Selection] Figure 7
