Experimental and Numerical Investigations of Ship Parametric Rolling in Regular Head Waves

China Ocean Engineering, 2018
Parametric rolling is one of five types of the ship stability failure modes as proposed by IMO. The periodic change of the metacentric height is often considered as the internal cause of this phenomenon. Parametric rolling is a complex nonlinear hydrodynamic problem, often accompanied by large amplitude vertical motions of ships.
