Ice Forces Russian Tankers Off Northern Sea Route After Two-Week Wait

A group of sanctioned Russian tankers became trapped in ice within the 55-kilometer-wide Vilkitsky Strait in July, a choke point on the Northern Sea Route north of the Arctic Circle. Two nuclear-powered icebreakers were summoned but required several days to reach the vessels. Only one tanker cleared the strait; the remainder waited up to two weeks, failed to pass even after the icebreakers arrived, and ultimately diverted to another route.

The incident contrasts with the Kremlin's promotion of the Northern Sea Route as a passage far from Ukrainian drones and potential European interdiction of shadow fleet ships. Russian crude oil and liquefied natural gas moved along the route at record volumes this year, but ice conditions remain unpredictable. Ksenia Vakhrusheva, who heads the Arctic project at the Lithuania-based group Bellona, said the episode shows that "less ice doesn't mean easier navigation." She said melting ice can break apart and jam into narrow straits, blocking vessels that lack an ice class rating.

President Vladimir Putin has called the route "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 in 2025, though not over its full length, and projected that volume would "almost double" by 2030. Kremlin officials had previously set a target of 80 million tons by 2024.

Other data point to a smaller scale. The Center for High North Logistics reported that Russia had shipped about 2 million tons of mainly crude oil, roughly 15 million barrels, along the full route to China and other Asian destinations by the end of September, mostly departing Murmansk. Reuters, citing traders and shipping data, put the total at about 20 million barrels by mid-October, a 50 percent rise from 2025 but roughly 1 percent of Russia's seaborne oil exports. Tomas Alexa, a senior analyst at Ambrey, described the volume as a surge "from a relatively low base." Alexa said Western sanctions constrain Russia's ability to build and service Arctic-capable ships, with spare parts and construction materials routed through third parties, while repair work once handled by Norwegian, Danish and Dutch firms is no longer available.

Traffic from other countries is increasing. On October 22, South Korea reported its first container ship had traveled the route, with officials calling it a shortcut to Europe while noting 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 and completed several voyages. Catherine Sendak of the Center for European Policy Analysis said Russia treats much of the Arctic as an inner waterway and that questions persist over tolls and services Moscow would provide commercial ships. She said she did not think good answers exist yet and raised the possibility that Russia might restrict access for others.

Security concerns are rising in the region. EU foreign affairs chief Kaja Kallas said on October 21, while outlining a new EU Arctic strategy, that the area "has become a front line of global power competition." NATO began its Arctic Sentry mission in February, and the United States announced plans last month to expand its military presence in Greenland. Vakhrusheva, with Bellona, said oil degrades more slowly in cold conditions and can spread across ice, and noted that Russia publishes no information on incidents along the route.
