    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.

     

    AIMS AND LEARNING OUTCOMES

    After attending lectures, the student will be able to analyse problems related to ship manoeuvrability (prediction of manoeuvrability characteristics, design of control means), having knowledge about the effects of the different elements (hull, appendages, propulsors, control means and their mutual interactions); moreover, the student will know how to develop a simple manoeuvrability simulator in Matlab / Simulink environment.

    TEACHING METHODS

    Theory and classwork.

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

    The teaching mode will be selected considering COVID emergency.

    EXAMS

    EXAM DESCRIPTION

    The student will be evaluated by means of an oral examination on all the course program. There are three exams in summer (June, July, September) and two in winter (January and February), plus some additional exams during year to be agreed with the professor.

    The exam will regard coursework had during the lectures and theory (usually two questions).

    ASSESSMENT METHODS

    The oral exam will consist in the verification of coursework carried out during lectures and in the verification of the level of knowledge gained by the student. The oral exam moreover will allow to evaluate the communicating skills of the student.
