—Hydrodynamic characteristics of twin skeg container vessel at different grid refinement and constant speeds were explored using Computational Fluid Dynamics (CFD). RANSE code Ansys CFX fitted with Shear Stress Transport (SST) turbulence model was used to carry out numerical simulations for the hull form of the twin skeg vessel model. Grid generator ICEM CFD was used to build hybrid grids for RANSE code solver. Set with Volume of Fluid (VOF) method, the program was utilised to capture the free surface flow around the hull. With emphasis given to the effect of mesh resolution on resistance, wave cut around hull and wave profile generated, comparison among different cases of grid refinement shows promising results.
