SESS3025 Marine Engineering

Module Overview

This module provides an overview of the main marine engineering systems found onboard merchant and naval vessels and their importance to ship design. It includes performance characteristics of prime movers such as diesel engines, steam and gas turbines and electric propulsion. The dynamic response of the main shaft and associated components is considered. An introduction is provided to auxiliary systems, including heating, ventilation and air-conditioning, refrigeration, the main fuel system, etc. Propeller-engine matching and selection of appropriate machinery configurations are also covered.

Aims and Objectives

Module Aims
