“…Among the main national interests of Russia in the Arctic, one can single out the use of the NSR as a national transport and logistics system, not only through the development of air and sea transport routes but also, through the development and maintenance of the railway (multimodal corridors), which in the future will contribute to the sustainable functioning of the AZR and integrate their regions into a single economic space. Article [43] describes the main tasks in the construction and operation of railway corridors in permafrost soils.…”

The Russian Arctic development is an investment direction, which is planned through a system of so-called “support zones” of various development degrees, it is a priority for Russia and can have a positive effect. Since integrated territorial development is associated with significant cargo flows of raw materials, materials and goods, logistics chains will include various transport modes, which will lead to the development of infrastructure (including the construction and reconstruction of seaports, the network of the railways and roads expansion) and the emergence of new international transport corridors (ITCs). A scientifically based solution to the problems of constructing a delivery route, including the location of transshipment points, logistics terminals and the rolling stock selection, will ensure the sustainable territories development through which ITCs pass. However, these tasks, which constitute the activity of organizing multimodal transportation, are associated with various types of risks, the successful solution of which, in this case, depends on the sustainable territorial development of these territories. Therefore, the research objective is to establish the relationship between the development of transport networks and the development of the Arctic region, the designation of possible prospects for the development of both multimodal transportation as a whole as a strategic event, and the contribution of each kind of transport, as well as the risks of creating and using international transport corridors, including cumulative impact on the environment. As a result of the literature analysis, we have considered the causes and consequences of the improper planning of supply chains and infrastructure, then we have indicated the role of new transport corridors in the development of territories. We have built a tree of problems in order to systematize risk situations and identify root causes and consequences. A method for calculating the cargo delivery time is proposed, taking into account the multimodality of logistics chains as well as measures that help reduce risks.

Under permafrost conditions, there are a large number of factors that complicate the construction and operation of pressure hydraulic transport systems. While designing new pressure systems and reconstructing existing ones, it is necessary to take into account possible unsteady processes in pressure pipelines. Elimination of the consequences of emergency situations accompanied by water leakage is difficult in harsh climatic conditions, while thermal effects on soils are not always possible to avoid. The purpose of the study was to identify the factors that most affect the risk of hydraulic shocks in pressure pipelines during aboveground laying of pipelines characteristic of permafrost areas. The method of characteristics used to solve differential equations of unsteady fluid motion is the basis of a computational model for determining flow parameters in the event of hydraulic shocks. On the basis of the calculations carried out, the diagrams of pressure changes in a pressure pipeline made of steel pipes are analyzed in the article. The influence of the propagation velocity of the hydraulic shock wave and the velocity of the steady-state fluid flow on the nature of the flow of the unsteady process and the amount of pressure during hydraulic shock in the pressure pipeline during overhead laying is estimated. Applying of activities aimed at preventing the occurrence of hydraulic shocks, including combined ones in order to increase the reliability of their action, is much cheaper than replacing damaged pipes and equipment, eliminating washouts with leaking water, loss of drinking water.
