Russian Tankers Reroute After Two-Week Ice Trap in Vilkitsky Strait

Sanctioned Russian tankers spent up to two weeks anchored in the Vilkitsky Strait in July before taking an alternate route. The vessels became trapped in ice far above the Arctic Circle, forcing them to wait for assistance that arrived too late to clear the narrow waterway efficiently. Only one tanker managed to pass through the strait during that period, while the rest diverted to avoid further delay.

The strait, located between the northern Siberian coast and Bolshevik Island, serves as a critical choke point on Russia's Northern Sea Route. It is approximately 55 kilometers wide. Two nuclear-powered icebreakers were positioned several days away by sea when the tankers stalled. Ksenia Vakhrusheva, who leads the Arctic project at the environmental group Bellona, explained that melting ice can break apart and pack tightly in narrow channels. She noted that less ice does not necessarily mean easier navigation for ships lacking specific ice-class ratings.

President Vladimir Putin has promoted the route as a reliable path to major markets. Last month, during the launch of the Vostok Oil project on the Taimyr Peninsula, he stated that 37 million tons of cargo moved along the route in 2025. He predicted that volume would almost double by 2030. This target follows an earlier Kremlin goal from 2019, which aimed for 80 million tons by 2024.

Independent data offers a different perspective on the route's volume. The Norway-funded Center for High North Logistics reported that Russia shipped about 2 million tons of cargo, mostly crude oil, along the full route to Asia by the end of September. Reuters cited traders and shipping data to place the total at about 20 million barrels by mid-October. This figure represents a 50 percent increase over 2025 levels but accounts for only about 1 percent of Russia's total seaborne oil exports. Tomas Alexa, a senior analyst at Ambrey, described the increase as a surge from a relatively low base.

Western sanctions complicate maintenance and construction for Arctic-capable vessels. Alexa noted that spare parts and materials often require routing through third parties. Repair services previously provided by Norwegian, Danish, and Dutch firms are no longer available to Russian operators. Other nations are beginning to test the waterway. South Korea reported on October 22 that its first container ship had used the route. Officials acknowledged difficult conditions, including large ice floes in the Bering and Vilkitsky straits. China also completed its first scheduled container service to Europe via the route this year.

Catherine Sendak of the Center for European Policy Analysis said Russia views much of the Arctic as an inner waterway. She raised questions about potential tolls and the services Moscow would offer commercial vessels. Sendak suggested that Russia might eventually limit access for other actors. Security tensions are rising in the region. EU foreign affairs chief Kaja Kallas described the Arctic as a front line of global power competition on October 21. NATO launched its Arctic Sentry mission in February, and the United States announced plans to expand its military presence in Greenland last month.

Environmental groups warn that increased shipping, particularly by aging tankers, poses risks. Vakhrusheva stated that oil degrades more slowly in cold conditions and can spread over ice. She added that Russia publishes no information on incidents along the route, making independent reporting difficult due to the area's remoteness.
