Aims

• Physical model testing, full-scale trials and empirical methods used in relation to ship powering problem.
• The methods adopted for estimating the resistance, performing basic propeller design and prediction the power requirements in the preliminary design stage.
• Introduce the fundamental concepts of seakeeping including motion of a floating body subject to regular and irregular waves.
• Introduce the fundamental concepts of added mass and fluid damping and consider method of obtain the necessary terms using experimental and empirical methods.
• Consider motion response including likely displaced position, velocity and/or accelerations, in terms of probability formula.
• To learn how to carry out design integration using formal optimization methods; to acquire knowledge on how and when to model single/multiple objective problems; to understand how detailed considerations affect design.

Teaching Activities

Teaching Rationale And Relationship

Lectures in the class or laboratory provide the students with general understanding of and familiarity with the fundamentals of the overall resistance and powering problem.
Example classes and coursework help the students to develop the associated skills required for the solution of the resistance and powering problem. Practicals provide the students with the opportunity to participate in experiments carried out in the towing tank and/or the cavitation tunnel. The subject of resistance and propulsion of marine vehicles is very broad, dynamics and diverse. Guided private study allows the student to read various classic books and the state-of-the-art papers more and catch-up with the latest developments in this attractive topic to encourage and develop their enthusiasm. The lectures are designed to assist students in the acquisition of a knowledge base that will facilitate understanding of concepts and detailed analysis methods. The tutorial sessions are supervised activities in which the students apply the knowledge that they gain during formal lectures and private study to predict the seakeeping, manoeuvring and course keeping characteristics of a ship.

The format of resits will be determined by the Board of Examiners

Other Assessment

Formative Assessments

Formative Assessment is an assessment which develops your skills in being assessed, allows for you to receive feedback, and prepares you for being assessed. However, it does not count to your final mark.

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.

Coursework tests the ability of the students to tackle an overall ship powering problem, to solve and to report it using taught skills by referring to much wider resources and communicating with others as in a "real design" case.
