One of the longer term solutions to such oil tanker accidents is much stricter control over the tankers themselves. The prestige was sailing under a flag of convenience, that of the Bahamas but owned by a company based in Liberia. At the same time it was managed by a greek company, chartered by a Russian firm and carrying the oil belonging to a british company from Latvia to Singapore, under a Greek captain but served by a philippino crew. Under these sorts of circumstances, inspections for the need for repairs and the awarding of fines for pollution become very complex issues and no one takes the blame. Clean-up costs will eventually go into hundreds of millions of euros, yet the prestige was only insured for 25 million in clean-up costs in the case of being wrecked. One of the eventual factors that will mitigate against future soills of this nature will be the banning of single-hulled oil tankers in European waters in favour of the much safer double-hulled tankers after the year 2015. This law was enacted following the the wreck of the Erica , another ageing single-hulled tanker off the shores of Brittany in 1999.
