The paper contains an overview of the currently existing methods for calculating the construction cost of a vessel and the possibility of their application at the stage of operational and technical justification of the vessel. The necessity of cost estimation is substantiated based on the analysis of the profitability of a new vessel, taking into account specific operating conditions. The difficulties encountered in calculating operating costs are described. The importance of such a component of operating costs as the calculation of fuel consumption on the move and the need to take into account when calculating the operating conditions of the vessel is noted. The results of comparative calculations for predicting the fuel consumption of new ships are presented, and their unsatisfactory accuracy is shown. The lack of accuracy of the existing methods for predicting power at the stage of operational and technical justification is shown. A method for predicting the effective power of main engines based on special hydrodynamic similarity criteria, which has a higher accuracy, is briefly described. A method for calculating the fuel consumption of the main engine is also described, which requires a minimum of initial data on the engine and propellers of a new vessel. The ways of increasing the reliability of the estimation of operating costs by constructing and using a model of the hull-propellers-engine complex, as well as constructing a model of the sailing operation are proposed. An algorithm is proposed for calculating the upper estimate of the construction cost of a vessel at a known freight rate and a given payback period of the vessel. The conclusion is made about the feasibility of using the presented method.
