Abstract
A maneuvering system for a ship provided with, in the stern, a port-side propulsion system, and a starboard-side propulsion system. For controlling the system, a forward or backward force of the shipis obtained by the difference between the forward and backward propulsion forces of the propulsion systems and a first turning moment in a turning direction of the ship generated by the propulsion forces is offset by a second turning moment in the turning direction of the ship generated by steering a port-side rudder, whereby the ship moves in a transversal manner toward its starboard side while rotation of the ship is avoided. A high degree of maneuverability is thereby achieved with a relatively simple maneuvering operation.
