Scope of Work:
Note: This study is part of a broader project “FPSO Roll Motions” (MMS Project 406).
The objective of the work presented in this thesis is to develop and validate a two dimensional Navier-Stokes solver to solve the problem of radiation due to the roll motions of a 2D FPSO hull at the free surface. Hulls with and without bilge keels are considered. The free surface effects and the viscous effects are decoupled and studied separately to get a better understanding of both phenomena. The present method aims at capturing the separated flow and the radiated wave profile and at predicting the roll hydrodynamic coefficients. The ultimate objective of the present work is to develop a 3D solver which can simulate roll motions of 3D ship hulls.
