Analysis of opportunities to reduce operation costs during transportation of fuel resources

The paper considers measures to reduce operating costs for the delivery of fuel resources to the settlements of the Yamal and Taz regions of the Yamalo-Nenets Autonomous District. The economic effect is achieved due to changes in marine transport fuel delivery schemes. The current transport scheme used by the Ob-Irtysh river shipping company involves the supply of diesel fuel from the Salekhard oil depot, to which it is delivered from the Omsk oil refinery (refinery). The scheme used has high transportation costs, because after the fuel is delivered, the ship goes back unloaded. An alternative fuel supply option is proposed, in which another type of fuel is imported into the settlements - liquefied natural gas. It is proposed that liquefied gas be delivered by an upgraded river-sea tanker of the Lenaneft project. The work provides a comparison of three transport schemes: traditional, when diesel is imported to all settlements; alternative, in which liquefied natural gas is delivered to all settlements; hybrid when settlements are supplied with diesel fuel or liquefied gas, depending on their geographical location. Analysis of the effectiveness of the circuits showed that the use of a hybrid circuit is most beneficial. Its use allows to reduce the empty mileage of the vessel by 685 km, and the total mileage - by 640 km. The reduction in the total transportation time is 13 days, which significantly increases the reliability and security of supplies due to the short navigation period in the region. Using the proposed measures will reduce operating costs by 1000.9 thousand rubles. in year. The increase in the efficiency of the hybrid transport scheme can be estimated at 7% relative to the total distance traveled by the vessel, and the economic benefit of using liquefied natural gas as a motor fuel at 44%. In addition to the economic benefits and the navigational benefits of the proposed scheme, natural gas is a more environmentally friendly fuel, which is critically important for the regions of the Arctic due to tougher environmental requirements.
