Course description

The course is subdivided into two main parts. The first one focuses on ship stability in intact and damage conditions, providing test examples and resolutions of several basic problems. The second one, instead, furnishes the required skills to assess the main components of ship resistance from both theoretical and experimental/numerical point of views. The course also provides the basics of ship design to increase the vessel hydrodynamic performances. Exercises and applications of the experimental methods complete the educational programme.

Knowledge and understanding: Students shall prove to know the main topics related to the assessment and evaluation of equilibrium conditions and stability of equilibrium for free-floating bodies in damage conditions, as well as evaluate and minimize the main components of ship resistance in calm water.

Ability to apply knowledge and understanding: Students shall prove to apply the acquired topics and theoretical proficiencies, required to evaluate the equilibrium conditions, the stability of equilibrium of free-floating bodies in damage conditions, as well as to minimize the main components of ship resistance in calm water.

Judgment autonomy: Students shall autonomously evaluate and assess the ship stability in damage conditions, applying the best resolutions to increase it.

Communicative Skills: Students shall acquire the skill of presenting a numerical application about the main topics of Naval Architecture, such as the experimental tests of ship powering and the assessment of equilibrium conditions for a damaged ship.

Learning Skills: Students shall be capable of continuously update their skills, by reading books, articles and rules (mainly in English), in order to acquire a good capacity of enhancing the own knowledge in the field of Naval Architecture.


It is mandatory to have passed the exams of Architettura e Statica della Nave and Manovrabilità e tenuta della nave al mare.


Ship stability: 12 h
Stability of intact and damaged ships. Ship watertight subdivision and probabilistic stability.

Ship resistance: 20 h
Ship resistance in calm water. Theoretical, experimental and numerical methods to assess the ship resistance. Experimental methods according to the ISSC procedures. Assessment of ship wake. Methods to predict the ship resistance.

Ship propellers: 10 h
Design of ship propellers. Cavitation and ship propellers. Non-conventional propellers (waterjets, supercavitating propellers, surface and cycloidal propellers). Numerical examples by means of ship softwares.

Exercises: 6 h
Experimental and theoretical exercises by ship softwares.

The course furnishes the basic elements about the equilibrium and stability of equilibrium of damaged ships. Besides, it also deals about the hydrodynamic basics concerning the ship powering and the working principle of the main types of ship propellers.

Teaching Methods

Frontal lessons, discussion of case studies, reading of the main national ed international rules


The teaching material (lecture notes in pdf format) is provided during the course.

Learning assessment

The exam consists of verifying the achievement of the previously defined educational goals, by an oral examination during which several numerical applications, generally focusing on the experimental tests of ship powering and the equilibrium conditions of damaged ships, are fully discussed.
