In line with increasing volumes of domestic and international freight, plans are in place to increase the capacity of sea ports in the Russian Arctic. This will primarily concern transport of hydrocarbons, coal, ores, and metals. A number of ports in the Arctic offer potential, including Sabetta, Lavna, Vykhodnoy, Kola, Dudinka, Dikson, Indiga, and Kandalaksha, amongst others. However, not all of them have been included in the comprehensive plan to expand and modernize transport infrastructure by 2024. Consensus has yet to be reached in the expert community or government as to which ports could be characterized as key hubs for the development of freight transport along the Northern Sea Route, ensuring safe navigation, and providing supplies to the North. What might be the consequences of increasing trans-shipment volumes in the Arctic basin? How can technological effectiveness and safety be ensured in the functioning of port infrastructure? What support measures for ports in the Arctic need to be introduced today? Might it be possible to apply free port status to key locations, as per Vladivostok?
