Arctic Traffic Jam Exposes Limits of Russia's Northern Sea Route Ambitions

In July, a group of sanctioned Russian tankers anchored in the Vilkitsky Strait after becoming stuck in ice, far above the Arctic Circle. The strait is a choke point about 55 kilometers wide between the northern Siberian coast and Bolshevik Island, on Russia's Northern Sea Route (NSR) to China. Help from two nuclear-powered icebreakers was several days' voyage away.

Only one of the tankers got through. The others waited up to two weeks for the icebreakers, still could not navigate the strait, and eventually took a different route.

The episode cuts against the Kremlin's heavily promoted vision of a newly open Arctic passage, one that lies farther from Ukrainian drone attacks and from possible European naval interdiction of shadow fleet vessels. Russian crude oil and liquefied natural gas moved along the route in record volumes this year, but conditions remain unpredictable. Ksenia Vakhrusheva, head of the Arctic project at the Lithuania-based environmental group Bellona, said the incident illustrates that "less ice doesn't mean easier navigation." She explained that melting ice can break up and pack tightly in narrow straits, blocking ships without an ice class.

President Vladimir Putin has described the NSR as "a reliable and safe path to the world's largest markets." Speaking last month at the launch of the Vostok Oil project on the Taimyr Peninsula, he said 37 million tons of cargo moved along the route, though not its full length, in 2025, and predicted that figure would "almost double" by 2030. Back in 2019, Kremlin officials were pursuing a target of 80 million tons by 2024.

Other figures also tell a more modest story. The Norway-funded Center for High North Logistics reported that by the end of September Russia had shipped about 2 million tons of mainly crude oil, roughly 15 million barrels, along the whole route to China and other Asian destinations, mostly from Murmansk. Reuters, citing traders and shipping data, reported that the total reached about 20 million barrels by mid-October, a 50 percent rise on 2025 but only around 1 percent of Russia's seaborne oil exports. Tomas Alexa, a senior analyst at the maritime security consultancy Ambrey, called it a surge "from a relatively low base."

Alexa said Western sanctions also hamper Russia's ability to build and maintain Arctic-capable vessels and infrastructure. Spare parts and construction materials often have to be routed through third parties, he said, while repair work once done by Norwegian, Danish and Dutch firms is no longer available.

Other countries are testing the route as well. On October 22, South Korea reported that its first container ship had used the NSR. Officials praised it as a shortcut to Europe but noted difficult conditions, including large ice floes in the Bering and Vilkitsky straits. China ran a scheduled container service to Europe along the route for the first time this year, completing several voyages.

Catherine Sendak of the Center for European Policy Analysis said Russia regards much of the Arctic as an inner waterway, and that questions remain over possible tolls and what services Moscow would offer commercial vessels. She said she did not think there were good answers yet, and wondered whether Russia might choose to limit access for other actors.

Security concerns are growing. EU foreign affairs chief Kaja Kallas said on October 21, while outlining a new EU Arctic strategy, that the region "has become a front line of global power competition." NATO launched its Arctic Sentry mission in February, and last month the United States announced plans to expand its military presence in Greenland.

Environmental groups warn of the risks from more shipping, especially by aging shadow fleet tankers. Vakhrusheva said oil degrades more slowly in cold conditions and can spread over ice, which could accelerate climate change effects. She also noted that Russia publishes no information on incidents along the route, and the area is so remote that no independent group can report on them.
