船舶の操縦システム、船舶、及び船舶の操縦方法
Document Type and Number:
Japanese Patent JP6786748
Kind Code:
B2
Abstract:
A maneuvering system for a ship 1 provided with, in the stern, two propulsion systems 2, 3, i.e., a port-side propulsion system 2 comprising a port-side propeller 2a and a port-side rudder 2a, and a starboard-side propulsion system 3 comprising a starboard-side propeller 3a and a starboard-side rudder 3b, wherein control is performed in which: a forward force Fx or backward force Fx of the ship 1 is obtained by the difference between the forward and backward propulsion forces Ta, Tb of the propulsion systems 2, 3 comprising the port-side propeller 2a and the starboard-side propeller 3a; and a first turning moment M1 in a turning direction of the ship generated by the propulsion forces Ta, Tb is offset by a second turning moment M2 in the turning direction of the ship 1 generated by steering the rudder 2b of the propulsion system 2 on one side of the ship, whereby the ship 1 is caused to move in a transversal manner toward the other side while rotation of the ship 1 is avoided. A high degree of maneuverability is thereby achieved with a relatively simple maneuvering operation.
