Title:
SHIP, SHIP CONTROLLER, SHIP CONTROL METHOD AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2023/277003
Kind Code:
A1
Abstract:
This ship, provided with an engine, a jet propulsion device, a ship controller and a ship position detection unit, the jet propulsion device is provided with a nozzle that emits a jet stream generated by the drive force outputted from the engine, and a bucket that changes the direction of the jet stream. The bucket positions include at least a forward position in which the jet propulsion device generates propulsion force for propelling the ship forward, a neutral position in which the jet propulsion device does not generate propulsion force for moving the ship, and a forward-side intermediate position between the forward position and the neutral position. The ship controller has a vessel fixed point hold mode which executes feedback control of the engine and the jet propulsion device on the basis of the deviation between pre-set target ship position and an actual ship position, and during the vessel fixed point hold mode, controls both the bucket positions, which includes the forward-side intermediate position, and controls the engine rotation speed.
