Common rail diesel-electric propulsion for small boats and yachts

The marine propulsion system is the heart of the ship. Its reliability will directly affect the safe navigation and operating costs of ship and its overall safety. The individuation of the best propulsive solution is one of the key technologies in marine field. Focusing on the study of comprehensive reliability, this study analyses operation environments of the marine propulsion system firstly, and then evaluate the comprehensive reliability of the chosen marine propulsion system. According to the fault tree of the marine propulsion system, a CRDID (Common Rail Direct Injection Diesel) electric hybrid marine engine system is taken as an example The result shows that a new engine CRDID-hybrid system can be reliably installed on small boats and yachts. It is believed that the knowledge gained in this study will provide a theoretical reference for research on comprehensive reliability of hybrid marine propulsion systems. © 2006-2015 Asian Research Publishing Network (ARPN).
