Abstract: Currently, the territory of the Russian Federation operates a single deep-water system (SDWS), which includes large shipping rivers and canals. Some of them are crossed by trunk pipelines, which, as practice shows, often have a shallow depth, which subsequently leads to deviations in the planned-altitude position. In addition to natural channel reformations, channel erosion is additionally affected by a moving vessel due to the constriction of the cross-sectional area of the channel and the operation of propellers. It is possible to assess the impact on the change in the intensity of channel erosion near an exposed MT by performing mathematical modeling. This article presents the results of mathematical modeling of the movement of a vessel of project 507G-020-012 along a section of the river on which an exposed trunk pipeline is located, at different speeds of the vessel's own motion and the river current.
