LEARNING OUTCOMES

The course aims to teach the basic notions for the design of naval vessels. It also aims to integrate the knowledge acquired in the previous courses and addresses the design issues according to the technological evolution of the sector.

AIMS AND LEARNING OUTCOMES

The course covers all phases of the design of a navy ship. During the semester, students will learn how to apply their knowledge of of naval architecture, marine structures, ship propulsion and machinery, in the various phases of the design spiral, by means of theoretical lessons and practical exercises with high design characterisation. A specific module will address the peculiar aspects of the design of conventional underwater units. The teaching will be supplemented by lectures by professionals in the sector and/or instructional visits to shipyards or to Italian Navy units.

At the end of the course the student:

• will be able to interpret an operational requirement of a navy ship ;
• will know the critical and peculiar aspects related to the design of such a ship type;
• will be able to face, applying his/her knowledge, and discuss with a critical spirit simple design problems.

PREREQUISITES

Due to the holistic nature of teaching in its approach to the ship as a whole, it is necessary to have strong skills in naval architecture and marine engineering subjects such as naval architecture, ship stability, shipbuilding, ship propulsion and machinery.

TEACHING METHODS

The course includes lectures and practical project exercises aimed at enhancing students' problem-solving skills. Particular attention is given to debriefing and discussion of the exercises.

SYLLABUS/CONTENT
