Course content

  • Introduction to stability of ships and floating structures, including; hydrostatic equilibrium of a floating body and intact stability regulations, including internal weight movement¿s e.g. heavy-lift.
  • External forces - environmental modelling.
  • Linear and nonlinear dynamic stability, parametric roll - Mathieu-effect, stability in flooding and damage condition and instability of ships.
  • Probabilistic assessments of ship and semisubmersibles rig capsize. And the probabilistic regulatory framework.
  • Stability aspect related to various ship and floating structures. Such as optimization of aspect related to design and operational characteristics, applicability of rules and regulations.
  • Computer methods. Use of relevant software, e.g. MATLAB or NAPA, for calculations and for visualizations.
  • Use of a model tank for assignments and tutorials/lab-demos, using different ship models.
  • Revision and analysis of typical critical scenarios and accidents investigation. Stability aspects of various operational situations, such as; Heavy lift, rig-moves and anchor handling, high-speed vessels, towing, icing, sub-sea operations, fishing, aquaculture, offshore vessels, passenger and ro-ro vessel, bulk and semisubmersibles bulk and ice breakers.
  • Design for safety.


Objectives of the course

Knowledge

The student have:

  • A thorough knowledge and understanding of the theoretical concepts of intact and damage stability.
  • Thorough knowledge and understanding of static and dynamic stability.
  • Knowledge of the regulatory framework in deterministic and probabilistic damage stability.
  • Understanding how waves and external forces influence the stability of all seagoing vessels.
  • Understanding of stability issues, of various vessels and floating structures, related to their design and operation.
  • Knowledge to conduct analysis of typical selected accidents and damage cases, and a thorough understanding of how this affects critical stability factors.                                                               

Skills

The student is:

  • Able to carry out and make use of existing knowledge and theories of ship stability, in real situations.
  • Able to analysis intact and damage stability.
  • Able to analysis static and dynamic stability.
  • Able to use the regulatory framework in deterministic and probabilistic damage stability.
  • Able to analysis how external forces influence the stability of all seagoing vessel.
  • Be able to analyse stability in critical scenarios and accidents.

Competence

The student is:

  • Able to utilize stability aspects and use appropriate theories to identify critical risk factors of ships and floating structures.
  • Able to reflect on their professional practice, work in groups, manage report writing, presentation, and function in a multi-disciplinary team.
