Title:
多機一軸船推進システムの運転方法及び多機一軸船推進システム
Document Type and Number:
Japanese Patent JP7365951
Kind Code:
B2
Abstract:
To smoothly carry out operation changeover to increase the number of engines without lowering speed of a vessel in a multiple machine uniaxial vessel propulsion system.SOLUTION: A multiple machine uniaxial vessel propulsion system 1 includes: a propeller 3; a first engine E1 for driving the propeller through a first clutch CL1; and a second engine E2 for driving the propeller through a second clutch CL2. When the propeller is driven by carrying out speed adjustment control of the first engine at first rotational speed, rotational speed of the second engine has speed adjustment carried out at second rotational speed which is higher speed than the first rotational speed, and transition to multiple machine coaxial propulsion is carried out by engaging the second clutch while applying restriction to speed adjustment control of the second engine. Number of driving engine is capable of being safely increased without generating any rapid load variation while maintaining load state of the engine. Deterioration in speed rising along with an increase in the number of engines is solved.SELECTED DRAWING: Figure 1
