MAR8038 : High Speed and Advanced Craft

Semester 2 Credit Value: 10
ECTS Credits: 5.0


A1 - special hydrodynamics and structural requirements associated with high speed and advanced
craft design
A2 - methods for predicting/analysing resistance and dynamic stability of planing mono-hull craft
A3 - methods for predicting/analysing seakeeping behaviour and dynamic stability of twin-hull
vessels with specific emphasis to SWATH (small waterplane area twin-hull) ships
A4 - waterjet principles and applications to high-speed craft
A5 - structural design aspects of high-speed mono/multi-hull craft

Outline Of Syllabus

This course consists of the topics related to "planning craft resistance and stability", "twin-hull (SWATH) seakeeping and stability", "Waterjet propulsion" and "Structural aspects of high speed and advanced craft". These topics are lectured by two different lecturers. In the following therefore the associated syllabuses are listed for each of these topics. However, there is no logical lecturing sequence amongst these topics. Usually, the Planing Craft Resistance and SWATH seakeeping topics are the first and lectured in parallel. This is followed by the Waterjets and Structural Aspects topics.
Planing Craft Resistance/Stability - resistance of planing craft, empiracal methods of calculation of resistance power requirements, porpoising stability.
Twin-hull (SWATH) Seakeeping/Stability - Twin-hull and SWATH seakeeping philolophy and design considerations; SWATH motion response prediction; dynamic stability of SWATH and stabilizer design; seakeeping laboratory demonstration.
Waterjets - general features and main components; efficiency calculation and preliminary selection of water jet; other features of waterjets.
Structural aspects - introduction (specific issues on structural design of high-speed craft; overview; design codes for high-speed craft); strength of panels; strength of stiffened panels: materials with particular reference to aluminium; strength of SWATHs.

Teaching Rationale And Relationship

Lectures in the classroom provide the students with general understanding of and familiarity of the special hydrodynamic and structural requirements (IKO1, ISO1); to learn techniques/develop skills to estimate/analyse resistance, seakeeping and dynamic stability behaviour (IKO2,3,4, ISO2); to select and analyse waterjets (IKO3, IKO5); to design/analyse the structures of high-speed and advanced craft (IKO6, ISO4).

Observation of video films on the special hydrodynamic behaviour of planing craft and SWATH ships with commentary helps the students to understand and have the knowledge of specific hydrodynamics problems (IKO1).

Seakeeping tests observations in the towing tanks with a representative SWATH vessel help the students to familiarise themselves with the seakeeping behaviour of SWATHS and experimental techniques to predict (ISO2).

This module covers a wide range of topics for different vessel types within relatively limited lecturing hours. The students are therefore strongly recommended and are guided to read classic and the state-of-the-art papers in their independent study time to support the lectures and to catch-up with the latest developments in this fast-developing subject area.

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.

Course work tests the ability of the students to tackle an overall planing craft powering and dynamic stability problem, to solve and to report it using taught skills by referring to much wider resources and communicating with others as well as a "real life" problem.

The Graduate Skills Framework entries indicated as 'A' are also assessed in this way.
