The numerical simulations were carried out using the open source toolbox OpenFOAM. An overset mesh method was applied, where two layers of mesh were generated, namely the background mesh and the overlapping body-fitted mesh. The incident focused wave groups were first validated against the experimental data at several positions. With the propagation of the waves, it was found that the waves generated by the numerical model were slightly dissipated due to numerical diffusion. Therefore, smaller wave crest was predicted from the numerical model. Then the simulations were conducted for the same wave conditions with the FPSO structure in place. The surface elevation and the pressure at several locations based on the validation criteria are reported.
