Amoco Cadiz was a very large crude carrier (VLCC) under the Liberian flag of convenience owned by Amoco. On 16 March 1978, she ran aground on Portsall Rocks, 5 km (3 mi) from the coast of Brittany, France; and ultimately split in three and sank, resulting in the largest oil spill of its kind in history to that date.
The Deepwater Horizon oil spill (also referred to as the BP oil spill, the BP oil disaster, the Gulf of Mexico oil spill, and the Macondo blowout) began on April 20, 2010, in the Gulf of Mexico on the BP-operated Macondo Prospect. Killing eleven people, it is considered the largest marine oil spill in the history of the petroleum industry and estimated to be 8% to 31% larger in volume than the previous largest, the Ixtoc I oil spill. The US Government estimated the total discharge at 4.9 million barrels (210 million US gal; 780,000 m3).
The Exxon Valdez oil spill occurred in Prince William Sound, Alaska, March 24, 1989, when Exxon Valdez, an oil tanker owned by Exxon Shipping Company, bound for Long Beach, California, struck Prince William Sound's Bligh Reef at 12:04 am local time and spilled 10.8 million US gallons (260,000 bbl; 41,000 m3) of crude oil over the next few days. It is considered to be one of the most devastating human-caused environmental disasters. The Valdez spill is the second largest in US waters, after the 2010 Deepwater Horizon oil spill, in terms of volume released
