Scope of Work:
Note: This study is part of a broader project “FPSO Roll Motions” (MMS Project 406)
The objective of the work presented here is to develop a two-dimensional unsteady Euler solver to solve the two-dimensional radiation problem due to the roll motion of a FPSO hull fitted with bilge keels. Visualization of the separated flow and vortex-shedding past the bilge keels as well as prediction of the roll hydrodynamic coefficients would be possible using the developed method.
This project also presents results for multi-component and podded propulsors, with the flow-field solved using an earlier developed vortex lattice method based potential flow solver [Kinnas et al. 1998] and axisymmetric/3-D steady Euler solver [Choi 2000].
