A Stydy on Marine Multi-Engine Eletric Propulsion System

In Case of Coastal Cruise Ship

Abstract

The authors have proposed a 20 feet container size Packaged electric Generator Unit (called PGU herinafter),which is integrated with a 800kw electric generator coupled with a 900 rpm diesel engine. The newly introduced marine machinery plant consist of many PGUs that cover both power sources of ship propulsion and onboard electric services. Thus, this new plant aims at higher reliability of ship's propulsion system having the redundancy by providing apare PGUs on one hand, and un-manned ebgine room by maintenance-free onboard on the other. This papaer introduces the above concept, which adopts coastal cruise ship as model ship.
