Learning unit contents

This course prepares students to master the basic notions about behavior of ship and offshore structures. It starts in SEPT and continues until MAY.

The course is mainly composed of lectures with examples and case studies. It is devided in three significant work units: statics, dynamics and resistance.

Statics: Introduction and purpose of static stability, Assessment of the center of gravity (CG), addition/removal/transfer of mass,effect of a suspended mass, principles of transverse stability, heeling moments and free surface effect, elementary principles of trim, the inclining experiment, loading conditions and rules, preparation of the intact stability booklet, and ship partially afloat.

Dynamics: Review of wave theories (regular and irregular waves), Vibrations and Damping, Heaving, Added mass for a Ship, Rolling in Calm Water, Rolling in waves, Powering in a seaway, Effect of design variables on Seakeeping.

Resistance and propulsion: Concept of ship resistance, Components of ship resistance, Froude hypothesis, What is viscous resistance and boundary layers, Residuary resistance, Dificulties of theoretical solution to residual resistance, ITTC57, ITTC 78, Practical determination, Towing tank tests, Numerical simulation methods. Introduction to ship propulsion, Efficiencies in a propulsion chain, Hull/Propeller interaction, Propeller geometry, Propeller theory, Sizing of the propeller and cavitation. Other propulsion types: Jet, Nozzle propeller, Thrusters...

A significant part of the course is devoted to manual practical work and computer-based work. Tests on models in a towing tank will also be carried out.

Learning outcomes of the learning unit

The main objective is to prepare students to tackle the challenges in a course: INTEGRATED DESIGN PROJECT OF SHIPS, SMALL CRAFTS and HIGH SPEED VESSELS. The lectures are organized in a way that they introduce important concepts as stages of ship design process.

This course contributes to the learning outcomes I.1, I.2, II.1, II.2, II.3, III.1, III.2, III.3, III.4, IV.1, IV.12, IV.14, V.1, V.2, VI.1, VI.2, VI.3, VII.1, VII.2, VII.3, VII.4, VII.5, VII.6 of the MSc in mechanical engineering.

Prerequisite knowledge and skills

Basic knowledge of ship design principles and general terminology in naval architecture.

Planned learning activities and teaching methods

The course includes practical works for each of the teaching units presented above. Final written work of each unit is marked.

Mode of delivery (face to face, distance learning, hybrid learning)

Blended learning


Additional information:

Face to face. Each learning unit (Static, Dynamic, and Propulsion and Resistance) consists of 5  1/2 day courses.
