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.
