Analysis of Transportation by Mixed-Type Ships along Siberian Rivers Using the Routes of the Northern Sea Route

The article examines transportation by mixed river–sea navigation ships connecting the Northern Sea Route (NSR) and the Siberian rivers—Ob, Yenisei, Khatanga, Anabar, Olenek, Lena, Yana, Indigirka and Kolyma for the period 2018–2021. The contribution of such transportation to the total cargo turnover of the Northern Sea Route has been studied. It has been shown that against the backdrop of overall growing shipping activity in the NSR waters, the volume of transported cargo and the share of river–sea cruises are systematically decreasing. An analysis of the main factors influencing the development of the identified negative trend was carried out. The age of the ships, their ice class, shipping activity on specific rivers, and the possibility of using rivers for the delivery of goods were studied.
