Module Details

Module Code: NAUT7006
Title: Ship Stability & Construction
Long Title: Ship Stability & Construction
NFQ Level: Intermediate
Valid From: Semester 1 - 2013/14 ( September 2013 )
Duration: 1 Semester
Credits: 5
Field of Study: 5253 - Nautical Science
Module Delivered in: 3 programme(s)
Module Description: This module provides the learner with the underpinning knowledge required to ensure that he/she can successfully complete and understand the calculations necessary to prove that a ship meets the International and National standards of intact ship stability. This is a requirement by the DOT for professional license.
This module also provides the learner with general knowledge of the principles of ship construction, plans, and the principal components of ship design.
 
Learning Outcomes
On successful completion of this module the learner will be able to:
# Learning Outcome Description
LO1 Complete the calculations necessary to show compliance with IMO Intact Stability for typical loaded conditions on board cargo ships.
LO2 Outline the design and construction requirements for specialised ship types.
LO3 Illustrate structural arrangements for merchant vessels.
LO4 State the requirements for watertight integrity and subdivision.
LO5 Outline the design and operation of ancillary systems on merchant vessels.
LO6 Break down the processes of ship building and maintenance.

Module Recommendations

This is prior learning (or a practical skill) that is strongly recommended before enrolment in this module. You may enrol in this module if you have not acquired the recommended learning but you will have considerable difficulty in passing (i.e. achieving the learning outcomes of) the module. While the prior learning is expressed as named MTU module(s) it also allows for learning (in another module or modules) which is equivalent to the learning specified in the named module(s).
