As well as general cargo ships and bulk cargo ships, tankers and container ships, heavy-lift vessels also use medium-sized, single-engine units with high-volume, medium-fast running four-stroke diesel engines, which drive a controllable pitch propeller (CPP) via a reduction gear. The CPP is necessary as most of these units also drive a generator via gearbox PTO from the main gearbox. This classic drive design requires careful adjustment of rotational vibration by means of a highly flexible coupling in the main drive line, between the diesel engine and the main transmission, as well as in the fast-running PTO line.
