Arctic Logistics: Vilkitsky Strait Ice Delays Tankers

Vessels carrying Russian crude and liquefied natural gas faced a two-week delay in July when they became trapped in ice within the Vilkitsky Strait. The strait, a 55-kilometer-wide choke point between the Siberian coast and Bolshevik Island, sits on the Northern Sea Route. Only one tanker in the group managed to pass through the ice. The remaining ships waited for two nuclear-powered icebreakers that were days away from the site. When the icebreakers arrived, they could not clear a path for the non-ice-class tankers. The vessels eventually altered their course to complete their voyages.

The incident challenges the Kremlin's narrative that the Northern Sea Route is a consistently open passage. Moscow has promoted the route as a secure alternative to traditional shipping lanes, positioning it farther from Ukrainian drone strikes and European naval forces. President Vladimir Putin described the route as a reliable path to major markets. Speaking in September at the Vostok Oil project launch in Taimyr, he stated that 37 million tons of cargo moved along the route in 2025. He predicted that volume would almost double by 2030. Officials previously targeted 80 million tons by 2024.

External data offers a different perspective on the route's capacity. The Norway-funded Center for High North Logistics reported that Russia shipped approximately 2 million tons of crude oil, or 15 million barrels, along the full route to Asia by late September. Reuters later reported that this total reached 20 million barrels by mid-October. That figure represents a 50 percent increase over 2025 levels but accounts for only 1 percent of Russia's total seaborne oil exports. Tomas Alexa, a senior analyst at Ambrey, characterized the growth as a surge from a relatively low base.

Western sanctions further constrain Russia's ability to sustain Arctic operations. Alexa noted that spare parts and construction materials often require routing through third parties. Repair work previously handled by Norwegian, Danish, and Dutch firms is no longer accessible to Russian operators. Other nations are also testing the waterway. South Korea reported on October 22 that its first container ship completed a voyage via the Northern Sea Route. Chinese operators ran their first scheduled container service to Europe along 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 noted that questions remain regarding potential tolls and service standards for commercial vessels. Kaja Kallas, the EU foreign affairs chief, described the region 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 in September to expand its military presence in Greenland. Ksenia Vakhrusheva of Bellona said that less ice does not guarantee easier navigation, as melting ice can pack tightly in narrow straits.

Environmental groups warn that increased shipping by aging tankers poses specific risks. Vakhrusheva explained that oil degrades slowly in cold conditions and can spread across ice surfaces. She added that Russia publishes no official data on incidents along the route, and the area's remoteness prevents independent monitoring.
