Vilkitsky Strait Ice Jams Force Russian Tankers to Wait Two Weeks

The Northern Sea Route is a critical artery for Russian energy exports, but the water remains treacherous. In July, a group of sanctioned Russian tankers became stranded in the Vilkitsky Strait.

The strait is a narrow choke point approximately 55 kilometers wide. It lies between the northern Siberian coast and Bolshevik Island. This location is far above the Arctic Circle and serves as a key segment of the route to China.

Only one of the stuck tankers managed to break through on its own. The remaining vessels waited up to two weeks for assistance. Help from two nuclear-powered icebreakers was days away by voyage.

Even with the icebreakers present, the fleet could not navigate the strait. The vessels eventually had to take a different route. Ksenia Vakhrusheva, head of the Arctic project at the environmental group Bellona, explained the mechanics of the jam. Melting ice breaks up and packs tightly in narrow channels. This blocks ships that lack a specific ice class. She noted that less ice does not mean easier navigation.

This incident challenges the Kremlin's narrative of a newly open and safe Arctic passage. President Vladimir Putin has described the route as a reliable path to major markets. Last month, at the launch of the Vostok Oil project in the Taimyr Peninsula, he announced that 37 million tons of cargo moved along the route in 2025. He predicted that figure would almost double by 2030.

Independent data suggests a more modest picture. The Norway-funded Center for High North Logistics reported that Russia shipped about 2 million tons of crude oil to Asia by the end of September. That volume equates to roughly 15 million barrels. Reuters reported that the total reached about 20 million barrels by mid-October. This represents a 50 percent rise over 2025 levels. However, it accounts for only about 1 percent of Russia's total seaborne oil exports.

Tomas Alexa, a senior analyst at the maritime security consultancy Ambrey, called the increase a surge from a relatively low base. He pointed out that Western sanctions hamper Russia's ability to build and maintain Arctic-capable vessels. Spare parts and construction materials often require routing through third parties. Repair work previously done by Norwegian, Danish, and Dutch firms is no longer available.

Other nations are testing the waters as well. South Korea reported on October 22 that its first container ship used the route. Officials described it as a shortcut to Europe but cited difficult conditions. They noted large ice floes in the Bering and Vilkitsky straits. China also ran a scheduled container service to Europe along the route for the first time this year.

Security dynamics are shifting in the region. EU foreign affairs chief Kaja Kallas stated on October 21 that the Arctic has become a front line of global power competition. NATO launched its Arctic Sentry mission in February. The United States announced plans last month to expand its military presence in Greenland.

Environmental risks accompany the increased traffic. Vakhrusheva noted that oil degrades more slowly in cold conditions. It can spread over ice, potentially accelerating climate change effects. She added that Russia publishes no information on incidents along the route. The area is so remote that no independent group can report on them.
