Norwegian authorities in the remote Arctic archipelago of Svalbard seized the Russian research vessel Professor Molchanov at the request of Ukraine’s state energy company Naftogaz, drawing a sharp condemnation from Russian President Vladimir Putin and setting off a high-stakes diplomatic clash over a multi-billion-dollar arbitration award.
The Seizure in Barentsburg and Court-Ordered Enforcement
The Governor of Svalbard, acting as the enforcement authority, seized the Professor Molchanov at the port of Barentsburg on Wednesday, September 2, following an order issued on August 31 by the Nord-Troms and Senja District Court. The vessel, which was carrying scientists, passengers, and supplies for Russian settlements on the Norwegian-administered archipelago, has been barred from leaving.
The ship had been travelling from Murmansk to the Russian settlement of Barentsburg carrying staff from the mining company Arktikugol, scientists and food supplies. The supply voyage to Svalbard had been made necessary by Norwegian sanctions that Moscow has described as a blockade.
It has been decided that the vessel will remain berthed in Barentsburg until the Governor or the Nord-Troms District Court decides otherwise, the Governor said in a statement, assuring that the authorities would take responsibility for the crew and passengers on board in cooperation with the Russian state-owned mining company Arktikugol.
Norwegian officials initially boarded the ship for what Svalbard Governor Lars Fause described as an ordinary border and customs inspection of a kind the ship had undergone numerous times before. On Wednesday, however, Norwegian police accompanied by an interpreter returned to read the court-ordered detention to the captain. Nobody aboard was arrested.
Naftogaz Pursuit of the Arbitration Award
The detention stems from a sprawling international legal battle originating from Russia’s 2014 annexation of Crimea. An arbitration tribunal in The Hague ordered Russia in 2023 to pay Naftogaz around $4.2 billion in compensation for assets expropriated on the Ukrainian peninsula of Crimea, which Russia annexed in 2014. The Nord-Troms and Senja District Court ordered the seizure on 31 August 2026 to secure enforcement of the Russian Federation’s outstanding obligations under the award, which amount to approximately $4.22 billion, plus interest and costs.
Following Moscow’s refusal to pay the 2023 award, Naftogaz has been petitioning national courts seeking orders to seize Russian commercial assets. The company said the seizure is part of global efforts to enforce an arbitral award secured by Naftogaz and other Group companies against the Russian Federation. The arbitral award had previously been recognised as enforceable in Norway, according to a statement from the Naftogaz Group. A Dutch court in late 2024 confirmed the enforceability of the arbitration award issued in The Hague, which awarded Naftogaz Group compensation for assets seized by Russia in 2014 in temporarily occupied Crimea.
“This is another important step towards restoring justice for Russia’s unlawful seizure of Naftogaz assets in Crimea. Russia cannot evade responsibility simply by refusing to comply with an international arbitral award. We will continue to pursue Russian assets around the world.”

Moscow’s Reaction and Diplomatic Fallout
The seizure triggered immediate diplomatic retaliation from Moscow. The Russian Foreign Ministry summoned Norway’s ambassador to Moscow, Heidi Olufsen, to deliver a resolute protest against the actions of the Norwegian authorities.
Speaking at the Eastern Economic Forum in Vladivostok, Russian President Vladimir Putin strongly condemned the action, comparing the capture of civilian vessels to state terrorism. Putin also criticized Ukrainian President Volodymyr Zelenskyy’s warning to foreign airlines to avoid Russia because of Ukrainian long-range drone attacks, saying such incidents complicated the prospects for future peace talks and adding that Ukraine’s allies were complicit in international terrorism by remaining silent on the issues.
The Russian Foreign Ministry stated that the ship belongs to Russia’s state weather and environmental monitoring agency Rosgidromet and carried workers, scientists and cargo to Russian settlements on one of the islands in Svalbard. The seizure of the vessel left Russian citizens and organizations there effectively under a state of blockade, the ministry said in a statement, adding that Moscow will seek to lift the vessel’s arrest.
The Lifeline for Barentsburg
The Professor Molchanov is used for commercial expedition cruises, including to Svalbard, which sits more than 800 kilometers north of the Norwegian mainland, and is known for its stunning snow-covered mountains, fjords and glaciers. The mining town Barentsburg on Svalbard is operated by the Russian state-owned company Arktikugol, where the coal mine is deep down in the permafrost below a mountain.
The exact number of people on board when the ship arrived in Barentsburg has not been officially confirmed, though the Professor Molchanov can accommodate up to 80 people, including at least 20 crew members and as many as 60 scientists and other expedition personnel. Norwegian media reported that around 50 passengers and crew were affected by the seizure, while Russian officials said that 21 people remained on board. Crew and passengers are safe, having been supplied with everything they need and continuing to work, with no Norwegian police or officials stationed on the vessel.
