Grace 1 (later renamed Adrian Darya 1)

Summary

The Iranian-flagged VLCC Grace 1 was detained by UK Royal Marines off Gibraltar on suspicion of transporting Iranian crude to Syria in violation of EU sanctions. The seizure — a rare UK naval boarding of a large tanker in Gibraltar Bay — triggered the reciprocal Stena Impero seizure two weeks later. Grace 1 was released after Gibraltar Supreme Court hearings + renamed Adrian Darya 1 under Iranian re-flag. Case became the definitive modern example of oil-sanctions enforcement via vessel-level naval action + the diplomatic-reciprocity risk that follows.
