Abstract

PURPOSE: To facilitate forward/backward propulsion and turning of a ship as well as bringing the ship alongside a wharf by a method wherein water is flowed by variable-vane pumps into ducts having openings at the bottom and the stern portion and into ducts which are branched from the former ducts and having opening at the ship's sides, and water is jetted outward from the ports of the ducts.
CONSTITUTION: For forward propulsion of the ship, pumps 4 creates water flows in ducts 3 in the direction from ports at the bottom to ports on the stern, and water is jetted outward to the stern. Adjustment of the pitch of variable vanes leads to adjustment of water jet amount and hence adjustment of the speed of the ship. For turning the ship to the right, the jet amount on the right is decreased and that on the left is increased. This turning is accelerated by making the vane pitch of the pumps negative on the right board side and positive on the left board side. For backward propulsion, the vane pitch is set negative on both right and left board sides, to cause water to flow reversely. For moving the ship to starboard, change-over valves 8 and 8' are closed, change-over valves 9 and 10 are opened, change-over valves 9' and 10' are closed, and water is flowed through the ducts 6 and 7 and jetted outward to the port side. Resulting in the rightward shifting of the ship.
