Norway has seized a Russian ship in Svalbard after a Norwegian court granted Ukrainian state-owned energy company Naftogaz the right to target the vessel as part of its efforts to recover compensation owed by Russia. The Professor Molchanov was placed under arrest in Barentsburg on Wednesday, 2 September, and cannot leave the port until Norwegian authorities or the court decide otherwise.
The Governor of Svalbard (Sysselmesteren på Svalbard) said the measure followed a ruling issued by the Nord-Troms and Senja District Court (Nord-Troms og Senja tingrett) on 31 August. The case stems from the expropriation of Naftogaz assets in Crimea following Russia’s annexation of the peninsula in 2014.
Why the Russian ship was seized in Svalbard
The seizure is an enforcement measure rather than a Norwegian sanction against the vessel. Naftogaz has been pursuing Russian state assets in several countries after Moscow failed to pay compensation awarded through international arbitration.
According to Naftogaz, the outstanding obligation now amounts to approximately $4.22 billion (€3.64 billion), plus interest and legal costs. The arbitral award has already been recognised as enforceable in Norway.
The original case began in 2016. In April 2023, an arbitration tribunal constituted under the auspices of the Permanent Court of Arbitration in The Hague ordered Russia to compensate Naftogaz for assets expropriated in Crimea. The Ukrainian company has since sought to enforce the award in jurisdictions where Russian assets can be identified.
The Professor Molchanov is owned by the Russian Federation. Under the Norwegian court order, it must remain at a location determined by the Governor of Svalbard. For now, the ship has been ordered to stay in Barentsburg, the Russian mining settlement on the archipelago.
Governor Lars Fause told NRK that Norwegian authorities would assist those affected by the measure, including helping crew members and passengers who need to return to Russia. The Governor is handling the situation in cooperation with Trust Arktikugol, the Russian state-owned company operating in Barentsburg.
The Professor Molchanov has a sensitive history in the Arctic
The legal basis for the seizure is the Naftogaz compensation case, but the Professor Molchanov has previously attracted attention because of its activities around Svalbard.
The vessel has for years conducted research and seabed surveys in the area. NRK has previously linked it to Russia’s Shirshov Institute of Oceanology, which is subject to sanctions imposed by the USA and Ukraine.
Kari Aga Myklebost, professor of Russian history at UiT The Arctic University of Norway, told NRK that the vessel has also been used in activities carrying a political and nationalist message. Among other things, it transported young people wearing Russian naval uniforms to Svalbard during Victory Day commemorations on 9 May 2026.
Myklebost described these activities as part of a broader pattern of Russian hybrid activity in the Arctic. This assessment, however, is separate from the judicial proceedings that led to the vessel being seized.
The Governor of Svalbard has similarly avoided linking the court order to broader Norwegian foreign or security policy. Fause said his office was treating it as a local legal matter and had informed the authorities in Barentsburg about both the reasons for the decision and the available legal process.
A legal dispute in a politically sensitive part of Norway
The case is particularly sensitive because of Svalbard’s unusual international status and Russia’s long-standing presence in Barentsburg. Norway exercises sovereignty over the archipelago under the Svalbard Treaty, while citizens and companies from treaty signatory states enjoy certain rights to economic activity there.
Senior researcher Arild Moe of the Fridtjof Nansen Institute told NRK that a protest from Russian authorities was likely, although its form remained unclear.
Russia and Norway have continued to manage practical relations in the Arctic despite the deterioration in European-Russian relations following the full-scale invasion of Ukraine. Svalbard has repeatedly become a focal point for disputes involving access, Russian activities and the interpretation of Norway’s authority over the archipelago.
The seizure also comes as European countries increasingly look for ways to enforce judgments and sanctions involving Russian assets. Naftogaz has already pursued similar enforcement proceedings abroad as it attempts to recover the compensation awarded over its Crimean properties.
For Norway, the immediate issue remains judicial rather than political: the Professor Molchanov must stay in Barentsburg while the Norwegian courts consider the enforcement proceedings. Any challenge to the seizure will have to be brought before the Nord-Troms and Senja District Court.
