Damaged Ro-Pax Vessel Time to Capsize
Paper in proceedings, 2012
The time for a RoPax vessel (M.S. Estonia) to capsize after a hull breach event is investigated with both physical model experiments and computer based time domai simulations. A two compartment side damage is modelled and a series of tests at stationary head wind/wave is performed. A parabolic inflow velocity model is developed to simulate water ingression through the damaged opening. A two dimensional multi-model sloshing model, composed by a non-linear pendulum model near resonance and an acceleration ratio model at non-resonance, is used for calculating ingressed water transverse center of gravity in the damaged compartment and on car deck.
