Abstract

This paper aims to test the feasibility of correcting the relative wave elevation (RWE) prediction from linear potential theory using simplified CFD simulation of the local hull model. Two-dimensional models with and without bow flare shape in the vertical plane are created to evaluate the nonlinear wave swell-up phenomenon at FPSO bow. By dipping the 2D hull model into calm water using sinusoidal velocity with different amplitudes, the performance of bow flare design on green water reduction is estimated and discussed. The data of RWE correction from 2D CFD study is applied to the numerical RWE prediction based on linear potential theory. For discrepancies showed in comparison with lab test measurement, 3D CFD study on fixed FPSO hull in beam sea wave is further conducted to preliminarily examine the 3D effect of bow flare.
