TEK-3011 Ship stability - 10 stp

• 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.
