OVERVIEW

The course deals with the ship buoyancy and stability, with a specific focus on the operational life of the ship. Topics are going to be treated both from a theroetical and a practical point of view. The matter plays a siginficant  role in the context of ship safety. 

AIMS AND CONTENT

LEARNING OUTCOMES

Standards concerning the stability and buoyancy, the leak problem, the rolling movement and stabilisation means, speed effects on the stability. Cargo handling and stowage. Preserve stability in case of damage. IMO requirements.

AIMS AND LEARNING OUTCOMES

The course enables the capability of:

Evaluate  the ship equilibrium in a specific laoding condition and the evaluation of the relevant stability as well;

Prrevent dangerous situations in relation with shift and lift of weights, liquid free surface and inclining effects

Understand the basic physics of a ship in damaged condition

Understand the stability requirements for a ship in intact or damage condition
