Fuel consumption of a ship advancing in a seaway is affected by added resistance in waves. In this paper, additional fuel consumption is approximated in relation to the increased resistance. Ship advancing in regular head waves with different speeds is examined. Calm water resistance is calculated according to the potential theory and ITTC 1957 correlation line. The added resistance is calculated using three-dimensional boundary element method based on the potential flow theory. Motion induced resistance due to heave and pitch as well as reflection induced resistance are taken into account. Therefore, overall assessment of added resistance in regular waves is achieved through quadratic transfer function. Evaluation of increased fuel consumption is made on the basis of estimated added resistance for different speeds and wave frequencies. Correlation of fuel consumption with various wave frequencies that the ship may encounter in its voyage is obtained.
