CODE 60389 ACADEMIC YEAR 2021/2022 CREDITS 6 cfu anno 2 INGEGNERIA NAVALE 8738 (LM-34) - GENOVA SCIENTIFIC DISCIPLINARY SECTOR ING-IND/01 LANGUAGE Italian (English on demand) TEACHING LOCATION GENOVA SEMESTER 1° Semester TEACHING MATERIALS AULAWEB 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.

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.
