Experimental study on parametric roll of a post-Panamax containership in short-crested irregular waves

Abstract

Free running model experiments of a post-Panamax containership were conducted to examine the danger of parametric roll in regular waves, long-crested and shortcrested irregular waves. As a result, parametric roll in head and bow waves were clearly recorded even in long-crested and short-crested irregular waves. From the experimental results, the effects of wave steepness, forward velocity, heading angle, irregularity of waves on parametric roll were systematically examined. © Springer Science+Business Media B.V. 2011.
