Aims

• To introduce the basic seakeeping qualities expected from a good ship and an offshore design.
• To provide knowledge underpinning the understanding of the factors influencing the seakeeping characteristics of ships and offshore structures.
• To develop skills required to predict the seakeeping behaviour of ships and offshore structures.
• Introduce the fundamental concepts of ship maneuvering in calm, deep water including the form of the equations of motion, typical nomenclature and regulatory issues.
• Introduce the experimental methods used for obtaining motion derivatives and the post processing of obtained data including the derivation of semi-empirical methods.
• Introduce linear analysis for preliminary estimations of performance and operability.

Outline Of Syllabus

Introduction to seakeeping; sea environment; regular waves and wave kinematics; added mass and hydrodynamic reaction forces of floating structures; wave excitation forces/moment acting on a floating structure; natural frequencies of a floating structure in heave, roll and pitch, uncoupled heaving motion of a floating structure; derivation and solution of motion response equations in regular waves; irregular seaway; forces and motion responses in an irregular seaway.

Teaching Rationale And Relationship

The lectures are designed to assist students in the acquisition of a knowledge base that will facilitate understanding of concepts and detailed analysis methods (IKO1-6).

The tutorial sessions are supervised activities in which the students apply the knowledge that they gain during formal lectures and private study (ISO1-4).

Assessment Methods

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

Assessment Rationale And Relationship

The written examinations 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.
