On November 13, 2002, while the Prestige was carrying a 77,000 metric tons cargo of two different grades of heavy fuel oil, one of its twelve tanks burst during a storm off Galicia, in northwestern Spain. Fearing that the ship would sink, the captain called for help from Spanish rescue workers, with the expectation that the vessel would be brought into harbour. However, pressure from local authorities forced the captain to steer the embattled ship away from the coast and head northwest. Reportedly after pressure from the French government, the vessel was once again forced to change its course and head southwards into Portuguese waters in order to avoid endangering France's southern coast. Fearing for its own shore, the Portuguese authorities promptly ordered its navy to intercept the ailing vessel and prevent it from approaching further.

With the French, Spanish and Portuguese governments refusing to allow the ship to dock in their ports, the integrity of the single hulled oil tanker was deteriorating quickly and soon the storm took its toll when it was reported that a 40 feet (12.2 m) section of the starboard hull had broken off, releasing a substantial amount of oil.

At around 8:00 AM on November 19, the ship split in half. It sank the same afternoon, releasing over 20 million USgals (75,708.2 m³) of oil into the sea. The oil tanker was reported to be about 250 kilometers from the Spanish coast at that time. An earlier oil slick had already reached the coast. The Greek captain of the Prestige, Apostolos Mangouras, was taken into custody, accused of not co-operating with salvage

Initially, the government thought just 17,000 tons of oil had been lost, and that the remaining 60,000 tons would freeze and not leak from the sunken tanker. In early 2003, it announced that half of the oil had been lost. Now that figure has risen to about 63,000 tons according to some sources. In 2004 the remaining 13,000 m³ of cargo oil was removed from the wreck, by means of aluminium shuttles and remotely operated vehicle

More than eighty percent of the tanker's 77,000 tons of fuel oil is now thought to have been spilled off Spain's north-west coast.

the disaster.

Hull cleanup

In the two years following the sinking, engineers used ROVs to seal cracks in the tanker's hull, now 4000 meters below the sea surface, and slowed the leakage to a trickle of 20 litres a day. By 2004, engineers had removed the oil still in the tanker by drilling of small holes in the wreck, using remotely operated submersible vehicles (ROVs) like the one that originally explored the wreck of the RMS Titanic. The oil was then pumped into large aluminium shuttles, specially manufactured for this salvage operation. The filled shuttles were then floated to the surface. The original plan to fill large bags with the oil proved to be too problematic and slow. After the oil removal was completed, a slurry rich in microbiologic agents was pumped in the hold to speed up the breakdown of any remaining oil. The total estimated cost of the operation was over €100 million.

A recent report by the Galicia-based Barrie de la Maza economic institute criticised the Spanish government's handling of the catastrophe. It estimated the cost of the clean-up to the Galician coast alone at €2.5 billion. The clean-up of the Exxon Valdez

, pushed for the ban of single-hulled tankers.

The government was criticized for its decision to tow the ailing wreck out to sea — where it split in two — rather than into a port. World Wildlife Fund's senior policy officer for shipping, Simon Walmsley believed most of the blame lay with the classification society. "It was reported as being substandard at one of the ports it visited before Spain. The whole inspection regime needs to be revamped and double-hulled tankers used instead," he says. The US and most other countries are phasing out single-hulled tankers by 2012.

Legal Consequences

For the world maritime industry, a key issue raised by the Prestige incident was whether classification societies can be held responsible for the consequences of incidents of this type. In May 2003, the Kingdom of Spain brought civil suit in the Southern District of New York

 (ABS), the Houston-based international classification society that had certified the Prestige as "in class" for its final voyage. The "in class" status states that the vessel is in compliance with all applicable rules and laws, not that it is or is not safe. On 2 January 2007, the docket in that lawsuit (SDNY 03-cv-03573) was dismissed. The presiding judge ruled that ABS is a "person" as defined by the International Convention on Civil Liability for Oil Pollution Damage

 (CLC) and, as such, is exempt from direct liability for pollution damage. Additionally, the Judge ruled that, since the United States is not a signatory to the International CLC, the US Courts lack the necessary jurisdiction to adjudicate the case. Spain's original damage claim against ABS was some $700 million.

International maritime trade publications including TradeWinds, Fairplay and Lloyd's List regularly presented the dispute as a possibly precedent-setting one that could prove fateful for international classification societies, whose assets are dwarfed by the scale of claims to which they could become subject.

Investigation

The massive environmental and financial costs of the spill has resulted in an ongoing inquiry into how a structurally deficient ship was able to travel out to sea, much less approach Spain.

Investigators have since learned that prior to the spill the Prestige had set sail from St. Petersburg

. Thus the Prestige sinking has exposed the difficulties in regulation posed by flags of convenience.

Others have argued that the Spanish government's refusal to allow the ship to take refuge in a sheltered port was a major contributing factor to the scale of the disaster.

Spanish investigators have concluded that the failure in the Prestige's hull was entirely predictable and indeed had been predicted already: the Prestige's two sister ships, Alexandros and Centaur, had been submitted to extensive inspections under the "Safe Hull" program in 1996. The organization which was in charge of the inspections, the American Bureau of Shipping

, found that both Alexandros and Centaur were in terminal decline. Due to metal fatigue in their hulls, modeling predicted that both ships would fail between frames 61 and 71 within five years. Alexandros, Centaur and a third sister ship, Apanemo were all scrapped between 1999 and 2002. For some reason, however, Prestige was not scrapped, and, little more than five years after the inspection, as predicted, Prestige's hull failed between frames 61 and 71.

Health problems among cleaning staff

Five years later after the cleaning activities, a study found that people participating in the cleaning activities, many of them volunteers, suffered several health problems, such as lung, cardiovascular, and chromosome diseases. This was found among a study of 800 involved Spanish Navy personnel.

Recent developments

In March 2006, new oil slicks were detected near the wreck of the Prestige which investigators found to match the type of oil the Prestige carried. A study released in December 2006 led by José Luis De Pablos, a physicist at Madrid's Center for Energetic and Environmental Research, concluded that 16,000 to 23,000 tons of oil remained in the wreck, as opposed to 700 to 1300 tons claimed by the Spanish government; that bioremediation

 of the remaining oil failed; and that bacteria corroding the hull could soon produce a rupture and quickly release much of the remaining oil and create another catastrophic spill. The report urged the government to take "prompt" action.

In March, eight years after the instruction of the Prestige case began in the Corcubion Court, UDNG, a small indepedentist Galician Party analyzed some of the main facts in the instruction as an evidence of strong corruption in Spanish judicial system.
