Amoco Cadiz oil spill Amoco Cadiz oil spill The oil tanker "Amoco Cadiz" ran aground on Portsall Rocks, from the coast of Brittany, France, on 16 March 1978, and ultimately split in three and sank, all together resulting in the largest oil spill of its kind in history to that date. NOAA estimates that the total oil spill amounted to 220,880 metric tonnes of oil. En route from the Persian Gulf to Rotterdam, Netherlands, via a scheduled stop at Lyme Bay, Great Britain, the ship encountered stormy weather with gale conditions and high seas while in the English Channel. At around 09:45, a heavy
Oil tanker designs suffered from stability problems caused by the free surface effect, where oil sloshing from side to side could cause a ship to capsize. But this approach of dividing the ship's storage space into smaller tanks virtually eliminated free-surface problems. This approach, almost universal today, was first used by Swan in the Nobel tankers "Blesk", "Lumen", and "Lux". Others point to , another design of Colonel Swan, as being the first modern oil tanker. It adopted the best practices from previous oil tanker designs to create the prototype for all subsequent vessels of the type. It was the first dedicated
