The teaching aims to present the systems, technologies, and physical and design principles underlying the propulsion of merchant and military naval vessels, with emphasis on sizing, catalog selection, and performance prediction.
The course has the aim to describe the physical aspects and the rule-based and technological constraints of the main ship propulsion systems, in order to provide design tools.
Upon completion of the course, the student will be able to:
Knowledge learned in the teachings of machinery, electrical engineering, construction science and hydrodynamics, and naval architecture are indispensable for understanding the teaching content.
Lectures, tutorials and active learning.
Generalities and design principles related to ship propulsion
Methods for power prediction
Engines and drives for ship propulsion
Marine gearboxes
Fixed-blade propeller-engine matching
Propulsion systems with steerable-blade propellers
Combined and hybrid systems
Off-design conditions
The shaft line
Fuels for ship propulsion
Basics on nuclear propulsion
Materials provided by the teacher on aulaweb, including notes, excerpts from standards, project guides, and component catalogs.

The examination consists of a written and an oral test:
Written design-type test lasting 3 hours. In the test, the candidate will be given some data and requirements of a propulsion system, and will be asked, for example, to schematize, design, size and evaluate one or more propulsion solutions. The exam is normally divided into 3-6 interconnected items. The written exam is “open-book,” so the use of manuals, handouts, books, regulations is allowed. Admission to oral examination with a minimum grade of 16/30.
Oral exam consisting of 2 open-ended questions on the course syllabus, in each of which the candidate must orally frame and illustrate one of the topics covered in the course by helping himself by representing the necessary diagrams and equations on the blackboard, and responding to any requests for clarification from the lecturer (approx. 15' per question). In order to pass the exam, both questions must be answered sufficiently.
The written examination, with a strong design characterization, aims to ascertain the candidate's ability to solve design problems of relevant complexity, integrating information from different sources, including data, catalogs, experimental test results, regulations and manuals, in order to synthesize a solution, assuming missing data and resolving ambiguities, motivating and arguing the choices adopted.
The oral oral examination aims to test the student's ability to argue about the topics learned and to illustrate the more conceptual and theoretical aspects. The use of the blackboard allows to verify the student's ability to express himself with the help of graphical representations and equations. Finally, the test allows to verify the student's ability to make simple approximate quantitative evaluations in the absence of data and computational tools.
