Now more than ever, reduction of the ship pollution and emissions, maximization of the energy efficiencies, enhancement of the safety requirements and minimization of the operational expenditure are required. Added resistance due to waves is one of the major components affecting ship performance in realistic operating conditions and it is also of interest as the main factor for the fuel consumption in a seaway. Therefore, the accurate prediction of the added resistance with ship motions is essential to evaluate the ship operational efficiency, plan a safe and energy efficient voyage and assess environmental impact. In this study, the numerical simulations of the added resistance and ship motions of KVLCC2 in regular head waves by the 3-D potential method and Computational Fluid Dynamics (CFD) solver are presented. Systematic validation and verification of the numerical computations against the available Experimental Fluid Dynamics (EFD) data including grid convergence tests demonstrate that reliable numerical results can be obtained for the ship in regular head waves. Numerical analysis is focused on the added resistance and vertical ship motions (heave and pitch motions) in a wide range of test cases for wave lengths and steepness with three different ship speeds (zero, assumed operating and design speeds).
