Paper presents results of studies on a parametric method of predicting ship operatingcosts - useful in the preliminary ship design. Conception and theoretical basis of the method are presented, identified are also factors of significant importance for the ship opera-ting costs, taking into account changes in the value of money. Approximation formulae forestimating the operating cost components have been developed as well as a computationalalgorithm based on a minimum Required Freight Rate (RFR). The useful character of themethod is illustrated by examples of operating cost predictions for four different ship typesdesigned in the Eureka project E!2772, i.e.: SINE 202 universal container carrier, SINE 203 oil producttanker, SINE 204 ro-ro ship and SINE 205 river-sea ship
