heal.abstract	The present work deals with the numerical prediction of self-propulsion characteristics of a tanker moving at low Froude number. Viscous flow calculations are combined with an actuator disk which models the propeller operation. The obtained results are used as input to experimental open water propeller charts to calculate the required propulsive characteristics at both model and full scale. In order to study how main actuator disk parameters influence its performance, several numerical experiments have been carries out by varying the circulation distribution and the length of the disk. In addition, the effect of the propeller diameter and its position on the calculated results is examined for the full ship.	en
