MAR8024 : Ship Performance at Sea

Semester 2 Credit Value: 10
ECTS Credits: 5.0


This module aims to develop knowledge and understanding of:
A1: Those technical factors which affect the performance of a ship hull and her machinery at sea.
A2: Main causes of performance losses (in-service) associated with the hull and propulsion, and methods to estimate these losses.
A3: Concept of maintenance, various maintenance systems and condition monitoring of main machinery systems.
A4: Systems reliability, failure mode and effect analysis and fault tree analysis.

Outline Of Syllabus

Since the course is consiting of the topics associated with 'Naval architecture (Hull and propulsor)' and 'Marine Engineering (Machinery), the following syllabuses are listed, in two groups accordingly:

Naval architecture (Hull and propulsor): Introduction to Module 842; Introduction to ship; Performance at sea (Review); Direct wind forces and moments; Induced forces and moments; Performance loss estimation; Effect of seaway on ship resistance; Effect of seaway on ship propulsion (if time allows); Hull roughness and Fouling.

Marine Engineering (Machinery): Performance and fuel economy; impact on plant lay out; 'Total energy' concepts; Marine fuels, fuel treatment; Maintenance as part of the ship's life cycle; Maintenance cost evaluation, failure mode and effect analysis, risk-based maintenance; Reliability and maintainability, fault tree analysis; failur rate; Concept of (intelligent) Condition Monitoring; Some techniques for intelligent monitoring; Condition monitoring of diesel engines.

Teaching Rationale And Relationship

Lectures in the class room provide the students with general understanding of: The physical phenomena and associated theory relating to performance losses in service and methods to estimate them (IKO1, ISO1); Effect of propulsion plant design on performance and its estimation (IKO2 and ISO2, 3 and 5), marine fuels, efficiency and analysis (IKO2, ISO2, 3 and 5); Concepts of maintenance, reliability and condition monitoring of main machinery systems, application and analysis (ISO2, 3 and 4).

Ship performance at sea is a broad topic while this specific course has relatively limited lecturing hours. The students are therefore strongly recommended and guided to read classic books and state-of-the-art papers to cover the topic in their independent study. Since the course material of Semester 2 will be lectured in condensed weeks, the students should allocate some of their independent study time to study this course material in advance of the condensed lecturing weeks.

Assessment Rationale And Relationship

The written examination allows the students to demonstrate their basic knowledge and understanding of the subject as well as to demonstrate their problem solving skills through short subject specific problems, under time pressure as required in industry.
The Graduate Skills Framework entries indicated as 'A' are also assessed in this way.
