Computational Fluid dynamics (CFD) has become nowadays an important tool in the process of hydrodynamic design of modern ships. CFD is used to model any phenomena related to fluid flow in a control volume like a ship or any offshore structure in the sea. In the present study, the Current force drag coefficients for a Colombian Navy Frigate in deep and shallow water are estimated through application of CFD, which are required to estimate the bollard pull for assisting maneuvers at port. The study shows the process of simulating the ship current drag coefficients using the CFD simulations method which is conducted using STAR-CCM+ software package. The Almirante Padilla class Frigate ship CFD scale model is investigated. The results show the ship current drag coefficient calculated considering a current speed of 1 knot with a 90° drift angle for the full-scale ship. The model configuration of the present simulation is based on the procedure recommended and published in the Lloyds Register OCIMF and the UFC mooring report for the estimation of the current drag coefficient.
