FPSO Roll Motions

Investigate the effect of the location and extent of the bilge keels on the motions of an FPSO hull and assess its effectiveness in mitigating roll motions. Develop a computationally efficient finite volume method to study the unsteady flow around a 2-D hull section subject to roll motions with or without bilge keels. Evaluate the motions of an FPSO hull in the absence of the bilge keels (WAMIT). Incorporate the effects of the bilge keels on the FPSO hull by analyzing the hull sections using the 2-D analysis, and by determining the modified hydrodynamic coefficients using a strip theory type of approach.
