The article provides a methodology for calculating the basic elements and characteristics of river dredgers at the stages of research design by means of the statistical method. For the study, the most common projects of river non-self-propelled dredgers with both a residential superstructure and without it, in a wide range of soil productivity, were used. The dependences of the total displacement and the main engine power on such basic technical data as suction dredger performance and loosening depth were analyzed in detail. Graphic dependencies and analytical expressions for determining the main suction dredger dimensions were obtained. The issue of choosing the length of the main dredger compartments is considered, which allows to solve the problem of pre-splitting the hull into compartments. The analysis of the accuracy of the obtained statistical dependencies for determining the length of the vessel is provided.
