AIMS AND CONTENT

LEARNING OUTCOMES

The unit deals with the study of marine propulsion systems and it is performed through a detailed analysis of the several system components, taking into account the mutual interactions. The module also deals with advanced design methodologies to catch the technological trends of the sector.

AIMS AND LEARNING OUTCOMES

The course aims to provide the students with advanced tools for the state of art design of complex propulsion systems, both from a technical and regulatory point of view. At the end of the module, the students will be able to independently evaluate different design solutions, and propose new ones with an awareness of the physical principles that drive the dynamics of marine propulsion.

Upon completion of the course, the student should:

- have acquired adequate knowledge regarding the study of the dynamics of complex propulsion systems;

- be able to apply the acquired knowledge on real design challenges;

- master the technical language;

- have developed self-learning skills that will enable them to independently investigate technologies on the frontier of the state of the art.

TEACHING METHODS

Classroom lectures and exercises, Industry expert workshops and educational visits.
