Knowledge and understanding: Understanding the fundamental principles of the operation of the various systems and machinery present in a ship: main engines, electric generators and auxiliary systems. Know the specific regulatory framework of the various components with particular reference to the safety of the vessel and the marine environment preservation. Understand the issues related to obtaining class and safety certificates.
Knowledge and understanding skills applied: being able to select the main and auxiliary machinery to draw up the design of ship systems including calculations concerning the sizing of all the different components through direct procedures or assisted by specific IT tools.
Making judgments: being able to apply the acquired knowledge to face the design process of ship systems regardless of its size.
Communication skills: knowing how to display, both in written and oral form, the design of ship systems in all its parts: from the selection of the main machinery, to the choices made in the sizing of all the main components, to their arrangement on board.
Ability to learn: to be able to collect information from textbooks and other material for the autonomous formulation of the design of the engine room of a ship regardless of its size.

Basic knowledge: naval architecture, ship construction, marine engineering, marine outfitting, technical drawing

The full operation of the ship is ensured by the installation on board of multiple systems, the most important of which is the propulsion system. In fact, all the results achieved during the ship's design in terms of hydrodynamic and structural optimization are nullified if the on-board systems, and in particular the propulsion system, are not adequate for the operational profile of the vessel in question. Therefore, in order to design the systems of a ship, it is not sufficient only to know the performance and operating principles of the main machinery (topics already covered in the marine machinery course), but it is necessary to become familiar with all the auxiliary subsystems and with their most convenient accommodation on board the ship. The "Marine Engineering" course will offer aspiring naval architects and marine engineers specific training, updated and calibrated to the real needs of the labor market. The frontal lessons, thanks to the collaboration established with Fincantieri, Wärtsilä Italia and Hexagon, will be integrated by monothematic seminars held by professional experts and by an introductory course in the use of the latest generation software (Intergraph SmartTM 3D).

Lectures and exercises led by the teacher performed in the computer room using specific software

All material available in Moodle2 http://moodle2.units.it

Oral examination on:
- Two questions regarding the program in the classroom (Knowledge and understanding).
- Presentation of the conceptual/functional online diagram of an on-board system developed according to guidelines learned in class and using IT tools used during the exercises (Applied knowledge and understanding). When presenting the system, the student will have to justify the choices made independently (autonomy of judgment and communication skills).

This course explores topics closely related to one or more goals of the United Nations 2030 Agenda for Sustainable Development (SDGs) (6, 7, 13, 14)
