TITLE Maritime Resistance Characterisation and Propulsion Systems

 
LEVEL 05 - Postgraduate Modular Diploma or Degree Course

 
ECTS CREDITS 5

 
DEPARTMENT Faculty of Engineering

 
DESCRIPTION Resistance and propulsion constitute a major role in the system design and operation of a marine vessel. The relationship between resistance and propulsion and the respective inefficiencies are explored to lay the foundation in providing and specifying the propulsion requirement and associated systems of a marine vessel.

All propulsion systems for marine vessels require a prime mover. Nowadays, the main prime movers for marine vessels are primarily diesel engines and gas turbines. A part of the study unit will focus on the performance of diesel engines and gas turbines, turbocharger and diesel engine matching, emission control equipment, fuel parameters and lubrication.

Study-unit Aims:

To provide students with a broad understanding of hull resistance and how this relates to propulsion systems design choices and operation and to familiarise students with the performance of diesel engines and gas turbines, turbocharger and diesel engine matching, emission control equipment, fuel parameters and lubrication.

Learning Outcomes:

1. Knowledge & Understanding
By the end of the study-unit the student will be able to:

- describe and quantify the dual physical effect of naked hull resistance;
- differentiate between resistance computation methods using applicable fluid dynamics and geometrical criteria;
- define and describe various characteristics of conventional and non-conventional propulsion systems;
- discuss the performance of diesel engines and gas turbines;
- explain turbocharger and diesel engine matching;
- describe emission control equipment;
- illustrate the different importance of the parameters of fuels and lubricants;
- read a single line diagram of the shipboard power system and describe the role of the various components.

2. Skills
By the end of the study-unit the student will be able to:

- compute the naked hull resistance using experimental data series and numerical methods;
- compute the hull efficiency and assess its impact on the effective power required to propel the ship;
- estimate the engine power required to propel a displacement type marine vessel;
- interpret the performance curves of diesel engines and gas turbines;
- analyze the problem of turbocharger and diesel engine matching;
- select the appropriate emission control equipment;
- assess specifications and test results of fuels and lubricants;
- explain the characteristics and perform basic calculations relating to the components shown in a shipboard power system single line diagram.
