Professor Molchanov was the only vessel operating a direct passenger link between the Russian mainland and Svalbard
Norwegian authorities have seized a Russian research vessel in Svalbard at the request of Ukraine’s state-owned energy company Naftogaz, amid growing tensions between Moscow and NATO states over access to and control of the Arctic.
The Professor Molchanov was detained on Wednesday while docked in Barentsburg, a Russian settlement on the Norwegian-administered archipelago. The Governor of Svalbard said the move followed an August 31 order by the Nord-Troms and Senja District Court granting Naftogaz the right to seize the ship. The vessel has been barred from leaving Barentsburg until further notice.
The crew and passengers aboard the vessel learned about the seizure from media reports, a TASS correspondent traveling with the expedition said. Russian Far East and Arctic Development Minister Aleksey Chekunkov said on Thursday that “the crew is safe,” adding that lawyers for the Arktikugol trust would soon issue a legal response and intended to challenge the seizure order.
The Professor Molchanov is a Russian state-owned research vessel operated by the country’s hydrometeorological service, Roshydromet. Alongside scientific expeditions, it has served since last year as a regular passenger and cargo link between Murmansk and Barentsburg, transporting scientists, employees of the state-owned Arktikugol, contractors, their families and supplies to the Russian settlements on Svalbard.
Direct air links between Russia and Svalbard ceased in 2020, while direct maritime passenger service was restored in 2025. The Professor Molchanov is currently the only vessel operating the route, with ten round trips between Murmansk and Barentsburg planned for 2026.
Under the 1920 Svalbard Treaty, Norway exercises sovereignty over the archipelago, while signatory nations are granted equal rights to engage in commercial and scientific activities there. Russia has maintained a presence on Svalbard for decades, with Arktikugol serving as its principal economic operator on the islands.
Naftogaz said it sought the seizure as part of an international effort to enforce a Hague arbitration award over assets it lost in Crimea following the peninsula’s reunification with Russia in 2014.
Russia has rejected the arbitration tribunal’s jurisdiction over the dispute, arguing that the Crimean assets in question could not qualify as Ukrainian investments made on Russian territory under the relevant bilateral investment treaty.
Acting Naftogaz chief Sergey Fedorenko praised the move as “another important step toward restoring justice,” pledging to continue the hunt for Russian assets worldwide.
Naftogaz, which claims Moscow currently owes it approximately $4.22 billion, plus interest and legal costs, has previously pursued Russian state property elsewhere in Europe. Finnish authorities froze a number of Russian-owned properties in 2024 at the company’s request. The Kremlin vowed to challenge the measures, while the Russian Foreign Ministry denounced them as illegitimate and warned of possible retaliatory steps.
The latest seizure comes just weeks after Moscow issued unusually explicit warnings against Western attempts to detain Russian vessels.
President Vladimir Putin described plans to seize Russian ships and sell their property as “piracy and robbery,” warning that Moscow would respond in kind and could do so in whatever part of the world it considered appropriate. Foreign Minister Sergey Lavrov subsequently said Russia would choose its own targets, including vessels operating in the interests of countries that had made such seizures their policy.
Tensions have also been mounting in the Arctic itself. In an article published earlier this week, Lavrov accused NATO states of seeking to turn the region into a “new front” against Russia and its partners. He pointed to large-scale Western military exercises and expanding command infrastructure near Russia’s northern borders, warning that the buildup increased the risk of an armed confrontation with potentially disastrous consequences.
Lavrov maintained that Moscow wants the Arctic to remain an area of peace and cooperation, but warned that Russia would defend its interests “by all available means” if confronted with hostile actions.
