AIMS AND CONTENT

AIMS AND LEARNING OUTCOMES

The course will enables the capabilities to:

design ships in relation with the most relevant rules dealing with the buoyancy and stability of ships in the intact and damaged conditions.

evaulate the final equilibrioum condition of a ship (and relevant stability) in case of damage

TEACHING METHODS

Lectures in classroom.

Assignements, practical applications during the semester.

SYLLABUS/CONTENT

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)

Floodable length curve

Permissible length curve

Stability requirements

•          Deterministic requirements for oil tankers, chemical tankers, gas carrier

•          Deterministic requirements navy ships

•          Probabilistic methodology for safety subdivision (SOLAS 2009)

Require subdivision index R

Attained subdivision index A

Probabilistic parameter relevant to the damage p,r,v

Probabilistic parameter relevant  the ship survivability s

Selected exercise

•          Ship Grounding

•          Stabillity of underwater vehicles
