Numerical and Experimental Investigation of Parametric Roll

open access: yes, 2013
The main purpose of this Master thesis is to provide insights about thesensitivity of parametric roll occurrence. Parametric roll resonance may leadto large roll angles experienced by the ship typically in longitudinal waves. Itis related to the periodic change of stability when the ship's wave encounterfrequency is approximately twice the rolling ...

Modeling and Control of Parametric Roll Resonance

open access: yes, 2011
Parametric roll resonance is a dangerous resonance phenomenon affecting several types of ships, such as destroyers, RO-RO paxes, cruise ships, fishing vessels and especially container ships. Worst case, parametric roll is capable of causing roll angles of at least 50 degrees, and damage in the tens of millions of US dollars.
