Analysis of the organization of sulfur export transportation in mixed river-sea traffic

Abstract

Sulfur is one of the export cargoes and occupies a significant share in the volume of water transport. The article analyzes the route from a sulfur production plant in the Astrakhan region to the seaport of Kavkaz, which involves motor transport, the specialized river port of Buzan, river fleet, a road transshipment complex in the seaport of Kavkaz, and sea vessels. It has been established that when transporting sulfur by water, mainly self-propelled fleets are used. The elements of the circular voyage of river ships, the technology and performance indicators of the ports were studied, the statistics of the supply of sea vessels to the port of Kavkaz for sulfur transshipment, the productivity of the fleet taking into account the actual duration of the circular voyage were analyzed. An option has been proposed for transporting sulfur on the analyzed route using pushed trains, which will allow, with an optimal ratio of the number of barges and pushers, to reduce energy costs with corresponding fuel savings and the number of crew.
