The United Kingdom government announced new sanctions targeting Russia's shadow fleet of tankers and the major oil companies Lukoil and Rosneft on Tuesday.
These measures aim to curb the illicit transport of oil and gas and tighten energy sanctions to bolster Ukrainian energy security. By targeting the "shadow fleet"—vessels used to bypass international price caps and sanctions—the UK seeks to reduce the revenue available to the Russian state.
Prime Minister Keir Starmer said the package while attending the G7 summit in Italy. The sanctions target 100 ships [2], which includes 44 specific shadow-fleet tankers [3]. These new restrictions bring the total number of sanctioned Russian shadow-fleet and LNG vessels to more than 600 [1].
Beyond individual vessels, the UK government targeted the operations of Lukoil and Rosneft. These companies are central to Russia's energy exports and the logistics of the shadow fleet. The UK move coincides with separate efforts by the European Union, which has targeted almost 200 ships [4] in its own campaign against the shadow fleet.
Officials said the goal is to close loopholes that allow Russia to move energy products through opaque ownership structures. The use of aging tankers with obscured registries has historically allowed Russia to maintain oil exports despite Western sanctions. By listing these specific vessels and companies, the UK intends to make it more difficult for these ships to access global ports, and insurance services.
“The UK move coincides with separate efforts by the European Union, which has targeted almost 200 ships.”
This escalation represents a shift toward targeting the logistics of energy transport rather than just the commodities themselves. By sanctioning the shadow fleet and the corporate entities managing them, the UK is attempting to dismantle the infrastructure that enables Russia to evade price caps. The coordination with G7 partners and the EU suggests a broader strategy to isolate the Russian energy sector from the global maritime insurance and shipping markets.
