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.
Definition of the basic motion equations and of the hydrodynamic characteristics which affect the ship behaviour in terms of manoeuvrability.
At the end of the course the student will be able to: - Understand the issues related to ship manoeuvrability (manoeuvrability prediction, design of control means), knowing the effects of the different elements (hull, appendages, propulsion systems, control means, mutual interactions); - Apply the notions described above for the design of the ship from the point of view of maneouvrability - Understand manoeuvring simulators developed in Matlab/Simulink environment - Develop simplified parts of manoeuvring simulators in Matlab / Simulink environment
The student is expected to have already acquired the fundamentals of naval architecture.
Lessons covering theory and classwork.
During classwork a simplified manoeuvrability simulator will be developed (in Excel and successively in Simulink)

All class schedules are posted on the EasyAcademy portal.
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).
Students with certified Spcific Learning Disorders, disabilities or other special educational needs are advised to contact the lecturere at the beginning of the course to agree on teaching and examination methods which, in compliance with the teaching objectives, take into account the student specific needs and provide suitable compensatory tools.
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.
The students have to sign up for the exams via the online website.
