While under tow, the Spanish tank vessel Aragon suffered damage during a storm on December 29, 1989, approximately 360 miles off the coast of Morocco. The damage resulted in the release of approximately 175,000 barrels of Mexican Maya Crude Oil into the Atlantic Ocean, near the Madeiran archipelago. The Portuguese Navy was in charge of the response. They monitored the initial movement of the oil until it made landfall. Approximately three weeks after the spill, pollution occurred on the Portuguese Island of Porto Santo, with oil believed to have been from the Aragon. This was later confirmed when oil samples were taken from the vessel. Portuguese authorities requested assistance from the International Tanker Owners Pollution Federation (ITOPF) and the European Economic Community (EEC) Task Force.

The ship, transporting 235,000 tons of crude oil was going from Spain to Mexico. Facing bad weather conditions on December the 26th, it had a propulsion engine failure due to diverse damage (propeller, rudder), then on the December 29th the breaking of the hull at the level of tanker No 1 caused the spillage of 25,000 tons of oil. After it had been temporarily sealed by divers, it was towed to Tenerife to unload the remaining part of the cargo.

There is a tremendous amount of mystery about this spill. CEDRE account is clearly confused on several points. For one thing, the ship must have been enroute Mexico to Spain. And Madiera is a fair way from the Canaries.

The EMSA site simple says "hull failure"

Not sure what effect the machinery failure had if any. Calling machinery failure a secondary cause, and the structural failure the primary cause.

We need a lot more info.
