Parametric rolling is one of the five failure modes introduced by the draft amendments to IMO’s 2008 IS Code. The aim of this paper is to study the use of CFD for the detection of parametric rolling. The ONR Tumblehome model 5613 was utilised and the simulation was set up using an overset mesh to allow motions to all 6 degrees of freedom. The results were validated against results presented from previous research. A number of different simulations were run and the results are presented and discussed herein.
