OVERVIEW

The course deals with the problem of ship controllability.

The different approaches for the assessment of ship manoeuvrability characteristics will be covered, introducing the basic equation of motion and considering experimental and numerical approaches.

Current IMO requirements will be presented, together with the standard manoeuvres adopted for the assessment of ship manoeuvrability.

AIMS AND CONTENT

LEARNING OUTCOMES

Definition of the basic motion equations and of the hydrodynamic characteristics which affect the ship behaviour in terms of manoeuvrability.

TEACHING METHODS

Theory and classwork.

During classwork a simplified manoeuvrability simulator will be developed (in Excel and successively in Simulink)
