| Description |
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. |
