A tanker carrying Russian diesel has passed through waters near the United Kingdom while reportedly heading toward the United States, raising fresh questions about the enforcement of international sanctions against Russian oil products.
The vessel, Leruo, remains subject to UK and European Union sanctions. Despite these restrictions, the tanker loaded a large cargo of diesel in Russia and continued its voyage toward the Atlantic, highlighting the differences between US, UK, and EU policies on Russian fuel imports.
Tanker Leruo Loaded 40,000 Tons of Russian Diesel
The Sierra Leone-flagged oil products tanker Leruo (IMO 9385831) loaded approximately 40,000 tonnes of diesel at the Russian port of Primorsk on October 16, 2026.
According to the vessel’s AIS signals, the tanker was heading toward the Atlantic with its destination listed as “For Orders.” However, reports indicate that the ship is expected to arrive in New York around November 7.
The tanker reportedly passed through the waters around the Shetland Islands on October 24. Although its precise route in relation to UK territorial waters remains unclear, the vessel may have sailed through the United Kingdom’s Exclusive Economic Zone (EEZ).
The passage has drawn attention because Leruo remains listed under both UK and EU sanctions. However, sailing through an EEZ does not automatically constitute a sanctions violation, and the legal position depends on the applicable restrictions and the vessel’s activities.
Different Sanctions Policies Create Challenges for Shipping
The reported voyage comes amid changes in the US approach to Russian diesel imports. The easing of certain US restrictions has opened the door for renewed shipments of Russian fuel, while the UK and EU continue to maintain their own sanctions measures.
These differences create a complicated operating environment for shipowners, charterers, cargo traders, and maritime authorities. A shipment that may be permitted under one country’s rules could still face restrictions under another jurisdiction.
For vessels carrying Russian petroleum products, the flag state, ownership structure, cargo origin, destination, and applicable sanctions lists can all affect the legal assessment of a voyage.
The Leruo case also highlights the difficulties of monitoring tanker movements using AIS data alone. Ships may broadcast changing destinations, while reported cargo details and intended discharge ports can remain unconfirmed until further information becomes available.
Two More Tankers Load Russian Diesel
The Leruo is not the only tanker reportedly involved in the renewed movement of Russian diesel.
The Malta-flagged product tanker Agioi Fanendes (IMO 9798375) was reported passing through the Skagerrak on October 26 with approximately 40,000 tonnes of diesel loaded at Primorsk. Its AIS destination was listed as “For Orders,” although New York had previously been reported as its intended destination.
Morocco has also been mentioned as a possible destination for renewed Russian diesel shipments, but the tanker’s final discharge port remains uncertain.
Meanwhile, the Palau-flagged tanker Dolunay (IMO 9327463) completed loading at Primorsk on October 16. The vessel was signaling an arrival at Alanya, Türkiye, around November 1.
Türkiye is also reported to be preparing to resume Russian diesel imports, taking advantage of the price difference between Russian supplies and fuel produced by domestic refineries.
The movements of these three vessels indicate that Russian diesel exports are attracting renewed attention from international shipping and energy markets. However, their final destinations and the regulatory status of individual cargoes should be assessed separately.
Russia Signals Plans to Increase Diesel Exports
Russian Deputy Prime Minister Alexander Novak has reportedly indicated that Russian diesel exports could reach approximately 3.5 million tonnes per month by the end of 2026, equivalent to roughly 875,000 barrels per day.
That would represent a substantial increase compared with the approximately 1.8 million tonnes of diesel reportedly covered by the initial US-Russia agreement.
If these export levels are achieved, tanker operators could see increased demand for transporting Russian refined petroleum products. At the same time, vessels involved in these trades may face closer scrutiny over sanctions compliance, insurance, banking arrangements, and port access.
For shipowners and operators, the changing rules underline the importance of conducting thorough compliance checks before accepting cargoes or entering into charter agreements connected to sanctioned entities or restricted trade.
What This Means for the Maritime Industry
The reported voyage of Leruo illustrates how changing energy policies can affect tanker operations across international waters. While AIS tracking provides useful information about a vessel’s movements, it does not independently establish its cargo, final destination, or compliance with sanctions.
As Russian diesel exports evolve, tanker operators, charterers, and maritime authorities will need to monitor regulatory changes carefully. The distinction between territorial waters and an exclusive economic zone is also important when assessing a vessel’s passage and the powers available to coastal states.
The situation remains fluid, and the final destinations of the tankers involved may change as their voyages progress.
