Amoco Cadiz oil spill

Amoco Cadiz anchor in Portsall

On 16 March 1978, Amoco Cadiz, a very large crude carrier (VLCC), owned by Amoco, split in three after running aground on Portsall Rocks, 5 km (3.1 mi) from the coast of Portsall, resulting in the largest oil spill of its kind in history to that date.[7]
