Russian vessels linked to the shadow fleet are still transiting UK waters in large numbers despite political warnings about possible boarding action. If sanctioned ships continue to pass at roughly the same pace after a public threat, it suggests enforcement signals alone are not yet enough to materially disrupt these routes.
For TankerMap readers, this matters because the story is about maritime sanctions credibility, not rhetoric. Continued shadow-fleet movements through UK-linked waters indicate persistent loopholes in monitoring and enforcement, with implications for insurance risk, compliance screening and the wider flow of sanctioned oil cargoes. It also shows how resilient opaque shipping networks remain even when the legal and political pressure rises.
