    Abstract

    Prediction of added resistance of a ship in waves is essential to evaluate vessel performance in a seaway. Also, added resistance in waves increases the fuel consumption. Today different methods are used to predict the added resistance of a ship in waves. Model tests play an important role, and researchers employ a range of computational methods, from two- dimensional potential flow in frequency domain to viscous time-domain CFD computations. These methods agree to a varying d gree for different wavelengths and wave headings. How much do these
    differences in added resistance prediction affect the overall voyage performance prediction in a realistic weather condition and a practical route is an interesting question which has been addressed by this paper. The results give an idea about the importance of added resistance formulation on economic operations of ships.
