SHIP PROPULSION SYSTEM AND SHIP HAVING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a ship propulsion system which is easily operated and comprises a plurality of shafts with stabilized output, and a ship having the propulsion system.SOLUTION: The ship propulsion system comprises: a first driving source 12; a first propeller shaft 16 connected with the first driving source; a first screw propeller 20 fixed to the first propeller shaft; a second driving source 14 having an output characteristics different from that of the first driving source; a second propeller shaft 18 connected with the second driving source; a second screw propeller 22 fixed to the second propeller shaft; a control device 24 which controls driving of the first driving source and the second driving source; and a torque sensor 27 which detects torque of the second propeller shaft. The control device can switch between an independent mode in which the first driving source and the second driving source are independently controlled and a follow-up mode in which driving of the first driving source is controlled based on detection result of the torque sensor so that output of the first driving source follows output of the second driving source.SELECTED DRAWING: Figure 1
