This paper addresses the hydrodynamic interaction and response of typical FPSO/FSO and LNG hull-forms with bilge keels. The hull-forms are assumed to be slender with the longitudinal length-scale exceeding the other two physical dimensions. This assumption allows the modeling of the flow around the hull-form in a 2-D strip-wise manner. A Finite Volume Method (FVM) based numerical model is developed to analyze the flow around the 2-D hull-sections, with and without bilge keels. The effect of the bilge keels in the damping of hull motions is presented with the application of the numerical scheme to a hull in forced roll motion, and its transient response in roll and heave decay.
