Nearly 200 Sanctioned Russia-Linked Shadow Fleet Vessels Entered UK Waters

Nearly 200 sanctioned Russia-linked ‘shadow fleet’ vessels have entered UK waters since the Prime Minister threatened stronger enforcement measures seven weeks ago, according to BBC Verify ship-tracking analysis. These vessels are assessed to be part of Moscow’s broader effort to evade international oil sanctions through opaque ownership structures, AIS (Automatic Identification System) manipulation, and evasive routing practices.

The continued transit of sanctioned vessels through UK waters raises questions regarding the effectiveness of current maritime enforcement mechanisms and the extent to which legal protections for freedom of navigation under the UN Convention on the Law of the Sea (UNCLOS) are constraining UK efforts to enforce sanctions and interdict Russian oil exports financing Moscow’s war in Ukraine.
