heal.abstract	The current diploma thesis was carried out as part of the studies of the writer in the school of Naval Architecture and Marine engineering of the National Technical Uni versity of Athens. The purpose of this thesis is the study of the effect of turbulence modelling in the calculation of the resistance of a ship in calm water, using RANS CFD methods. Initially, a convergence study of the computational meshes used for the cal culation of the resistance coefficient was done utilizing the k-ω SST model. Then, simulations have been conducted using some variations of the original model. Finally, corrections for the hull roughness have been implemented on the original moment, and simulations to attain results regarding this case have also been realised.	el
