Course Objective

The basic principles of ship's propulsive, electric generation and auxiliary engines will be presented based on previous knowledge of applied thermodynamics. Diesel, steam and gas turbine prime moversystem with their relative merits are also coverded by the course as well as treaties on the electrical and auxiliary systems used on board.

Learning Outcomes of the Course Unit

1   To gain an insight in the theory and marine applications of conventional heat engine systems
2   To be able to assess different projects for ship propulsion and auxiliary power plants
3   To be further trained on tools of how to undertake research and gain an insight on the design tools to be used in marine field
4   To be able to demonstrate knowledge and understanding of performance characteristics of various types of marine engines
5   To be able to select appropriate shaft arrangement
6   To be able to understand the function of the main engineering systems on a ship and to carry out design calculations relating to them
7   To be able to understand the relationship between the engine rating and the propeller
8   To evaluate the environmental impact of a range of marine propulsion systems
