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.

AIMS AND LEARNING OUTCOMES

the course will enalble the capabilities to:

- design ships (especially passenger ships) in compliance with the most important international rules about buoyancy and stability of ships both in intact and damaged conditions

- calculate the final equilibrium condition and the relevan stability of a ship in damged condition

TEACHING METHODS

Lectures in classrom;

Practical applications in classrooms

SYLLABUS/CONTENT

Safety as a constraint/target in the design of units having passengers as a payload   

Introduction to the Rule Making environment: IMO, Flag State, Classification Societies.

The righting arm (RA):

- relation between  RA and ship main dimensions (midship section)

- the RA at very high heel angles

- the down-flooding angle: watertight and weather-tight closures

- influence on the righting arm deriving from

• Trim (initial trim, “free to trim”)

• Wave profile

The linear roll motion of ship for the evaluation of  the roll period

Inclining moments:

- effect of wind

- effect of turning at speed

The Intact Stability Code 2008

- General stability criteria

- Wave and wind combined effect (whether criterion)

- Special requirements for passenger ships

Lightship weigh estimation

Inclining experiment

Solutions for the ship in damage:

- loading of weight  method

- constant displacement method

Deterministic methodology for safety subdivision (former SOLAS)

- Allowable length curve

Probabilistic methodology for safety subdivision (SOLAS 2009)

- Required subdivision index R

- Attained subdivision index A

- Probabilistic parameter relevant to the damage p,r,v

- Probabilistic parameter relevant  the ship survivability s

Grounding

The stability of underwater vehicles
