N2 - This paper addresses the hydrodynamic interaction and the response of typical FPSO and LNG hull-forms with an emphasis on roll. In particular, the study focuses on the prediction of the roll response of hulls in free-decay motions and also in regular waves for various wave frequencies and for hulls with or without bilge keels. A 2-D finite volume method-based Navier-Sokes solver (NS2D) is applied to analyze the flow around the hull-sections. The effectiveness of using bilge keels on roll reduction is presented, and the bilge keel loads on the up-wave and down-wave sides of the hull are examined.
