Course description

The course aims to provide students the methodology tools for understanding the operation, the architecture and the performance of the fluid machinery used for the marine propulsion. Thus, the course will be devoted to deep the knowledge on the energy conversions systems such as steam turbines systems, gas turbines systems and internal combustion engines.
The course, according to the topic dealt with, will furnish some competencies required by the STCW Convention, as amended, for Deck Officers and Marine Engineers at Operational Level, embodied in the MIT decree dated 19th December 2016, namely “Percorso formativo per accedere alle figure professionali di Allievo Ufficiale di Coperta e Allievo Ufficiale di Macchina”.

Understanding of the aspects concerning the integration of the auxiliary systems needed for the marine propulsion

Conoscenza e capacità di comprensione applicate (applying knowledge and understanding)
Applying knowledge on performance measurements of the marine propulsion systems
Applying knowledge on performance measurements of the auxiliary systems
Applying understanding optimization criteria according to the on-board installation

Autonomia di giudizio (making judgements)
Making judgements on the marine propulsion systems with respect to the specific application field
Making judgements on the choice of the engine operating parameters according to the energy and environmental performances.

Abilità comunicative (communication skills)
Communication skills on the ability to easily explain to people the operation of fluid machines and components for the marine propulsion.
Communication skills on the interaction with colleagues during lessons and seminars activities.

Capacità di apprendere (learning skills)
Learning skills by finding the tools useful for improving the knowledge
Learning skills by finding the tools useful for elaborating the own critical analysis concerning energy and environmental performances.


The student has to know the main contents of the courses of Applied thermodynamics and heat transfer:
- Thermodynamic properties
- Thermodynamics laws and their application for the analysis of the energty conversion systems


The course focuses on the study of propulsion and mechanical systems on board ships with particular reference to the basic principles on the construction and operation of energy systems for propulsion (48h)
Therefore, the following topics will be covered in detail:
Introduction to turbomachinery (6 h)
Introduction to the study of fluid machines and their classification. Euler equation. Definition of the degree of reaction. Action and reaction fluid machines. Blade profiles and velocity triangles.
Basic principles on the construction and operation of marine diesel engines (18 h)
Reference cycles: Diesel cycle and Otto cycle. 2-stroke and 4-stroke engines. Combustion in diesel engines. Fuels for marine diesel engines. Supercharging systems. Fuel injection systems. Lubricants and lubrication systems. Steering systems in propulsion systems with diesel engines and their control.
Basic principles on the construction and operation of steam and gas turbine plants (24 h)
The Rankine Cycle. The Hirn Cycle. Methods for increasing efficiency: reheating, thermal regeneration. Real cycles. The boilers in steam propulsion systems.
Joule cycle. Efficiency and power of the gas turbine cycles. Thermal-Rigeneration. Inter-refrigeration and post-combustion. Combined systems.

The course aims to provide students with the basic methodological tools for the study of propulsion systems for ships. In particular, the aspects linked to the operation of exothermic plants, such as steam plants (based on Rankine cycle and Hirn cycle), and endothermic plants (gas turbine and diesel engines) will be presented in detail.

The course, with reference to the covered topics, will provide some of the skills required by the STCW 2010 International Convention to access the professional figures of Deck Officer and Engineer, received by the Ministerial Decree MIT 19 December 2016 "Training path to access the professional figures of Official Student of Deck and Engineer Officer ".
In particular, the course, in relation to what is reported in Annex II of the previous decree for Engineer Officer Students, provides skills on:
- propulsion and mechanical systems on board ships with particular reference to the basic principles on the construction and operation of energy systems for propulsion (48h)

Teaching Methods

The teaching includes theoretical lessons and exercises in the classroom. The exercises will be performed together and a discussion on the results will be carried out.

Notes of the lecturer

Learning assessment

The exam, which lasts about 30 minutes, consists of an oral test during which the level of knowledge of both the main issues related to the operating conditions and construction of marine propulsion systems and detailed information related to auxiliary systems will be assessed. In addition, the ability in explaining the conceptual aspects and the mastery in the oral presentation of the arguments will be also taken into account.
