The article offers the technique of developing progressive ship-hour norms of loading procedures on river transport based on methods of probability theory and mathematical statistics. The technique includes the algorithm that consists of sequentially implemented stages: the study of technical characteristics and technological operations on the mooring where cargo handling is taking place; obtaining the actual reporting data about time expenses when loading (unloading) with preliminary division of operations to technological or unproductive ones; processing statistical data on time, isolating technological operations and leaving out unproductive ones; calculating a statistical row of actual productivity determining boundaries of distribution, mean value and a root-mean-square deviation of productivity of loading (unloading); processing a statistical row and its approximation for receiving theoretical distribution, checking convergence of statistical and theoretical distributions; developing a specific norm taking into account progressiveness; determination of economic efficiency of the offered norms; working out proposals on implementing norms. The authors consider establishing a ship-hour norm based on the obtained average productivity of cargo handling operations or, taking into account progressiveness, with increase at value of a mean squared deviation. Efficiency of implementing new ship-hour norms is defined for the port (due to the increase of freight turnover and the appropriate lowering cost of cargo transhipment) and for the shipowner (due to decreasing time of cargo operations and saving on the maintenance of fleet under processing). Approbation of the technique was carried out in Togliatti port, "Volzhsky" type ships being taken as an example. There has been determined expected efficiency of implementing new norms for ports and for shipowners (in the amount of 1,48 and 3,89 million rubles for a single navigation, respectively).
