The water jet pusher which generates thrust of automatic

摘要

PROBLEM TO BE SOLVED: To expand the applicable range of a water jet propulsion ship in which the fixed point can be automatically held, and the maneuverability is enhanced, in particular, in a low speed range.;SOLUTION: An automated fixed point holding device of a water jet propulsion ship having a water jet propeller (1) and a side thruster (5) comprises an azimuth sensor (10), a wind direction and wind velocity sensor (12), a ship position sensor (13), a propulsion control device (3) to control the operation of the water jet propeller and the side thruster, and control panels (20 and 21) to perform the control instruction to the propulsion control device. The propulsion control device maintains the azimuth by operating the water jet propeller and the side thruster based on the control instruction from the control panels, the azimuth and the wind direction and wind velocity. Further, the propulsion control device maintains the ship position by operating the water jet propeller and the side thruster based on the control instruction from the control panels, the azimuth the wind direction and wind velocity, and the ship position.;COPYRIGHT: (C)2005,JPO&NCIPI
