The sanctioned oil tanker Chariot Tide — listed by the European Union and the United Kingdom for carrying Russian crude in violation of sanctions — lost engine power off the coast of Spain and was drifting in international waters before being escorted by a Spanish maritime rescue vessel toward Tanger Med in Morocco.
Rather than detaining the vessel, Spanish authorities monitored the situation and deployed a rescue escort — the ship Clara Campoamor — to guide the disabled tanker safely to port for inspection and resolution.
The incident highlights the complex challenge of enforcing sanctions at sea. Even ships formally blacklisted can navigate long distances, switch names/flags, and exploit gaps in maritime enforcement while carrying sanctioned oil.
The Chariot Tide is part of a growing global “shadow fleet” of tankers used by Russia, Venezuela, Iran and others to circumvent Western sanctions via opaque ownership, flag changes, and dodged tracking — now estimated to include over a thousand vessels.
