An analysis was made of changes in the transport sector associated with the introduction of trade and logistics sanctions against Russia. The main directions of development of transport infrastructure and international transport corridors are considered. The operational transport and logistics solutions of the Russian business are analyzed. Top-priority issues of modernizing the transport infrastructure in the current situation are raised. In support of their solution, a set of models for adapting the transport infrastructure of Russia in the context of sanctions is proposed.

The authors of the article study the basic risks in development of hydrocarbon offshore fields in the Arctic as well as methods of managing the existing risks. Development of hydrocarbon offshore fields in the Arctic is connected with numerous challenges due to its unique natural and climatic conditions (ice pack, squally winds, rough sea, etc.). Any activity in such conditions makes high demands for the investment (realization of such projects is extremely capital intensive) and for environmental and industrial security. Due to the high level of work complexity currently only one offshore field is being developed in the Arctic. However, Russian energy companies are considering the perspective possibility of extraction of hydrocarbon resources in such conditions. In order to explore the Arctic offshore fields efficiently it is necessary to apply the methods of risk management which are able to minimize the possibility of unwanted events. In most cases the method of risk management is chosen depending on the stage of realization of the project on developing an offshore field: prospecting, exploration or exploitation of a deposit. The authors of the article conditionally divide the risk management methods into two categories: universal (which can be applied at any of the above mentioned stages of the deposit's development) and unique (to be used only at one certain stage). The analysis conducted made it possible to reveal the main advantages and disadvantages of the risk management methods under consideration. The combination of universal and unique methods became the basis for the risk management system which takes into account the specifics of the stages of development of Arctic offshore hydrocarbon fields.

As world experience shows, from a geographical point of view there are many settlements, the access to which is mainly possible by sea transport ensuring the delivery of large volumes of goods. Quite often it is possible to get to the areas blocked by a thickness of ice only using icebreaking equipment. The development of the Arctic and the Northern Sea Route, ensuring the security of the state, and the growth of Arctic transportation are priority areas in the maritime policy of states with access to ice-covered waters. Therefore, the issues related to the development of the icebreaking fleet are quite relevant and significant. The purpose of the study is to show the development stages of the icebreaking fleet and determine its significance for Russia and other countries. The authors set the task of analyzing, systematizing and summarizing the world's most significant studies for science and the shipping industry on the development of the icebreaking fleet, key trends in the construction of icebreakers, as well as the prospects for the development and renewal of icebreaking in general. The study utilized theoretical research methods (system method, construction from the general to the specific, etc.). The discussion of the study results is widely tested through scientific and practical discussion not only at all-Russian, but also at international conferences, symposia, round tables on the development of the icebreaking fleet. The study examined the history of the construction of the largest icebreakers known to the world, the modern state of the icebreaking fleet on the example of the Russian Federation and revealed certain features of the construction of nuclear icebreakers. Conclusions were made on the need to increase the environmental friendliness of icebreakers, on the role of the icebreaking fleet for state economies. The study provides characteristics of a number of icebreakers that allow assessing the development dynamics and the current state of the icebreaking fleet (including in Russia). The issues related to improving the maneuvering characteristics of icebreakers were considered, as well as the connection between the use of the icebreaking fleet and research and rescue operations in the Arctic zone was revealed.

The authors attempt to assess the environmental and economic efficiency of investment projects for the goods transportation by the northern seas of Russia taking into account the relevance of the topic of cargo transportation by means of the “Northern Sea Route” (NSR) and new concept of the digital format of the “Northern Sea Transit Corridor” (NSTC) implemented by the “Rosatom” State Corporation. The structure of import-export and transit traffic by the NSR in 2020 is considered. The goal of the article is to evaluate the efficiency of investment project for the goods transportation forwards and backwards by the NSR from Murmansk city to PetropavlovskKamchatsky city using the example of the “Andrey Osipov” shipping facility. Some indicators were assessed: planned revenue, payback period; NPV, environmental damage. The following results are obtained: the payback period is 10 years; by using the naval fuel oil over a ten-year period, 1101.6 tons of SOx, 143.1 tons of CO2, 288.9 tons of NOx will be emitted. In addition, the authors propose an innovative approach to creation of ships from new materials and technologies based on the modern paradigm of “Accelerated Digital Certification”.

The development of mineral resources in the Arctic territories is one of the priorities of the state policy of Russia. This endeavor requires modern technologies, high-quality personnel, and a large number of labor resources. However, the regions of the Arctic are characterized by difficult working and living conditions, which makes them unattractive to the working population. The research objectives were to study the importance of Arctic mineral resources for the Russian economy, the Arctic mineral resource potential, and the migration attractiveness of Arctic regions. The migration processes in these locations were analyzed and modeled using a new econometric tool—complex-valued regression models. The authors assume that the attractiveness of the Arctic regions is determined by the level of their social and economic development and can be assessed using a number of indicators. A comparative analysis of four regions that are entirely in the Arctic zone of the Russian Federation was carried out based on the calculation of integral indicators of the social and economic attractiveness of these territories. Forecasting migration growth using the proposed complex-valued models produced better results than simple trend extrapolation. The authors conclude that complex-valued economic models can be successfully used to forecast migration processes in the Arctic regions of Russia. Understanding and predicting migration processes in the Arctic will make it possible to develop recommendations for attracting labor resources to the region, which will contribute to the successful development of its resource potential. The methodology of this study includes desk studies, a graphical method, arithmetic calculations, correlation analysis, statistical analysis, and the methods of the complex-valued economy.
