When a flexible propulsion system was proposed as the drive unit for the MV Crown Odysee the author's company had to find a multi-engined drive which operated economically at three fundamental speeds and at the same time satisfied the electricity demand. The enhanced safety and reliability standards were met by using a multi-engined drive supported by an efficient gearing system. This drive operates with two controllable pitch propellers (CPPs), each driven by a primary and a secondary engine. The secondary motors can operate through two reduction gears and can also act as generators. Gear selection only takes place when the propeller is at rest, and the gear changes to each propeller can take place separately. Experience suggests that flexibly-mounted generating systems pose fewer problems than separate flexibly-mounted engines. This paper gives details of the propulsion system developed and the methods adopted to reduce structure-borne noise from the propulsion and auxiliary engines.
