A method of predicting main propulsion power for inland waterways push trains

This paper presents a method of predicting effective power demand (brake horse power – B.H.P.) for propulsion of inland waterways push train, useful in the preliminary design stages. By using it, on the basis of known main particulars of a given push train, i.e. its length, breadth, draught and speed, a generalized Admiralty formula can be determined and then the pusher propulsion power can be preliminarily predicted by making use of the elaborated structure of the formula. Application of the method is illustrated on the example of a two-segment push train of inland waterways passenger ship designed in the frame of the Eureka INCOWATRANS E!3065 project.
