Abstract (en)

A ship maneuvering system includes: a front-rear propulsor that outputs thrust toward both sides in a front-rear direction of a hull; a lateral propulsor that outputs thrust toward both sides in a lateral direction of the hull; at least one mooring structure located close to a stern of the hull and at least one mooring structure located close to a bow of the hull, each of the mooring structures being configured to wind and unwind a mooring rope; and ship maneuvering circuitry configured to control operations of the front-rear propulsor, the lateral propulsor, and the mooring structures. When making the hull reach a quay, with the mooring ropes locked to mooring posts located at the quay, the ship maneuvering circuitry makes the mooring structures wind the mooring ropes, and at the same time, makes at least one of the front-rear propulsor and the lateral propulsor output the thrust by which tension of each mooring rope is reduced.
