The article discusses the logistics transport routes for the supply of natural gas from Arctic region located on the shelf of the northern seas and the Yamal Peninsula. The description of the development of the transport network is given with the results of a comparative calculation of the unit cost of transporting gas in different phase states along different transport routes. The purpose of the study is to consider possible options for the delivery of hydrocarbon raw materials to the consumer with the lowest transport costs. The considered transport routes and the obtained preliminary data are applicable to solving linear programming problems. Schematically shows the supply of natural gas to consumers from the northern fields through the pipeline system in a compressed state and by sea in liquefied form. The fields of the western part of the Yamal Peninsula and the Nadym-Pur-Taz region are part of a single gas supply system, the fields of the eastern part of the Yamal Peninsula, the shelf and the western part of the Gydan Peninsula are removed from the existing gas infrastructure, which significantly complicates the monetization of finished products. Due to the close connection of the Arctic regions with the Arctic Ocean, shipping by sea is becoming an integral part of the development of offshore and coastal fields. Climatic conditions and underdeveloped infrastructure require a detailed study of possible transport routes, taking into account the reliability of the equipment involved in transport chains and the financial component of the relevant investment projects. In order to identify the optimal directions of gas supplies from an economic point of view, various route options are considered, including with a change in the phase state of the energy carrier. The author considers the integrated gas delivery route to the consumer, combining marine and pipeline gas transportation, suggests new supply routes, shows the methodology for preparing initial information, and performs calculations for existing, project and possible transport directions.
