MAR8024 : Ship Performance at Sea

  • Offered for Year: 2022/23
  • Module Leader(s): Dr David Trodden
  • Owning School: Engineering
  • Teaching Location: Newcastle City Campus
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: Estimation of energy performance and indicators.
A4: Assessment of environmental ship performance and impact.

Outline Of Syllabus

Introduction to Ship Performance at Sea, review the objectives of study.
Forces acting on a ship in her natural environment (seaway). Voluntary and involuntary speed reduction.
Direct and indirect forces and assessment of such on ships.
Wind and wave forces and how to estimate them.
Effect of seaway on Resistance and Propulsion.
Hull roughness and fouling.
Performance loss estimation.
Environmental impact of ships in service.
Ways to assess the environmental performance of a ship in a seaway.
Design and Operational aspects for energy efficiency of a ship in service
Environmental/Energy Indexing methods
Environmental regulations
Pollution Prevention methods

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 (IKO1 and ISO2, and 3). Issues of environmental performance and estimation (IKO2, ISO5). Fitting the estimation of environmental forces, hull and propulsion reactions to that environment to arrive at a solution to estimate performance loss of a ship in a seaway (ISO 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.

Should the public health situation require it, the present-in-person teaching activities will be replaced by synchronous online sessions. ). In that case, in-person lectures, practical PC sessions and practical laboratory sessions will be replaced by online sessions, Windows Virtual Desktop online sessions, demonstrations and simulations.

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.

Should the public health situation require it, the planned examination scheduled to be completed present-in-person will be replaced by an open book, online examination to be completed within a defined 24 hour period.
