Study on proposed respectively method for marine propulsion plant system: a case study on passenger ship

The improvement of ship performance and propulsive efficiency has been addressed in this article. This proposed method will enhance the operational area of marine propulsion plant and ship energy efficiency management. The main object of study is the relationship between main diesel engine–gearbox–shafting system–marine propeller. The effective power (Ne) and revolution (n) of main diesel engine have been established throughout the empirical equations in this research. The research results are analyzed and validated for a certain passenger ship namely Sealife Legend 02. The collected results would be discussed with the previous study of Stapersma and Woud “Matching Propulsion Engine with Propulsor” that has been published on Journal of Marine Engineering and Technology. The operational energy efficiency of marine propulsion plant system would be enlarged through this proposed method. This article is significant for the ship-operators and the ship-owners in the management of marine propulsion plant system nowadays.
