37 Million Tons Claimed, But Two Weeks in Ice Reveal Arctic Route Limits

A fleet of sanctioned Russian tankers sat motionless in the Vilkitsky Strait in July, trapped in ice far above the Arctic Circle. The strait, a narrow passage roughly 55 kilometers wide between the Siberian coast and Bolshevik Island, is a critical choke point on the Northern Sea Route. With nuclear-powered icebreakers days away, the vessels faced a stall that highlighted the physical constraints of the corridor.

The standoff lasted up to two weeks. Only one tanker managed to break through. The rest remained stuck, unable to navigate the packed ice even with assistance, and eventually rerouted to reach their destinations. The delay contradicted the narrative of an easily accessible Arctic highway promoted by Moscow.

President Vladimir Putin has touted the route as a reliable path to major markets. Speaking at the launch of the Vostok Oil project on the Taimyr Peninsula last month, he cited figures showing 37 million tons of cargo moved along the route in 2025. He predicted that volume would almost double by 2030, a target that surpasses the 80 million tons goal set by Kremlin officials in 2019.

Independent data suggests the actual throughput is more modest. The Norway-funded Center for High North Logistics reported that Russia shipped approximately 2 million tons of cargo, mostly crude oil, along the full route to Asia by the end of September. By mid-October, Reuters data indicated the total had risen to about 20 million barrels, a 50 percent increase from the previous year. However, that volume represents only about 1 percent of Russia's total seaborne oil exports.

Tomas Alexa, a senior analyst at Ambrey, described the recent growth as a surge from a low base. He noted that Western sanctions complicate the maintenance of the fleet. Repair work previously handled by Norwegian, Danish, and Dutch firms is no longer available, and spare parts often require complex routing through third parties to reach Arctic-capable vessels.

Ksenia Vakhrusheva, head of the Arctic project at Bellona, explained the mechanics of the blockage. She stated that melting ice does not necessarily ease navigation. Instead, the ice can break up and pack tightly in narrow straits, creating barriers for ships that lack specific ice classes. This dynamic undermines the assumption that warming temperatures automatically open the route.

Other nations are beginning to test the waterway. South Korea reported on October 22 that its first container ship had completed a transit. Chinese operators also ran a scheduled container service to Europe for the first time this year. While officials viewed the route as a shortcut, they acknowledged difficult conditions, including large ice floes in the Bering and Vilkitsky straits.

Catherine Sendak of the Center for European Policy Analysis pointed out unresolved regulatory questions. Russia treats much of the Arctic as an inner waterway, leaving commercial operators uncertain about tolls and services. Sendak expressed doubt that Moscow has clear answers and suggested Russia might limit access for other actors.

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

Environmental risks accompany the increased traffic. Vakhrusheva warned that oil degrades more slowly in cold conditions and can spread across ice, potentially accelerating climate effects. She noted that Russia publishes no information on incidents along the route, and the remote nature of the area prevents independent groups from verifying events.
