Ukraine has published data on 20 vessels that carry Russian oil and liquefied natural gas or refuel the sanctioned fleet, parts of the logistics network the Kremlin uses to fund its war, Ukraine's Defense Intelligence reports. All 20 are under British or Ukrainian sanctions, and only one faces US restrictions.

Russia’s shadow fleet runs on roughly 500 aging ships of uncertain ownership that dodge sanctions and keep oil money flowing. That seaborne oil trade is worth more than 80 billion euros a year.

The headline vessel is the Russian ship Portovyy, an LNG carrier and floating gas store owned by the sanctioned Gazprom since 2021, according to the agency. On 15 August 2026, it left the Gulf of Finland with Russian LNG for the first time since November 2021, sailing the Northern Sea Route to the Chinese port of Beihai to unload.

Portovyy is now at the Zhoushan Huafeng Shipyard in China, which has been set as the site for its maintenance, intelligence says, an example of the foreign yards Kyiv wants closed to the sanctioned fleet.

Russia buys up gas carriers through shells

Two more gas carriers show how Moscow expanded the fleet in spring 2026 through front companies, intelligence said. The Avacha, once owned by China’s Jovo Energy, was bought by the little-known Tudor Maritime of the Marshall Islands, took the Russian flag in June, and now ships gas from the Arctic LNG 2 project to Beihai.

The Chaivo, formerly owned by Greece’s Maran Gas Maritime, was also bought by Tudor Maritime and moved under the Russian flag in July. Now it carries cargo to Beihai from a floating gas storage facility off Kamchatka, intelligence says.

A call to close the loopholes

Intelligence urged partners to act together: tighten control over sales of commercially owned ships, block servicing of the sanctioned fleet at foreign yards, and cut off the energy revenue that Russia turns into weapons against civilians.

Russia is building ice-class ships at home and, at the same time, widening its shadow fleet through offshore networks. The UK Foreign Office made the same point on 1 October, saying Moscow is assembling a new shadow fleet to keep its gas revenues flowing.
