Accidental and illegal discharges of oil by ships at sea

Identification

More oil is released into seas by illegal discharges than by shipping accidents. Operational discharges by ships are prohibited in the North Sea, Baltic Sea, Black Sea and Mediterranean Sea � all International Maritime Organization (IMO) �special areas�. Under the Bonn Agreement, North Sea states carry out aerial surveillance as an aid to detecting and combating pollution and to prevent violations of anti-pollution regulations. The Helsinki Convention established an aerial surveillance over the Baltic Sea and nine countries participate in this, including four ACs: Estonia, Latvia, Lithuania and Poland. The number of detected illegal oil spills decreased in the North Sea and the Baltic Sea. The implementation of Directive 2000/59/EC requiring Member States to set up adequate port reception facilities for ship-generated waste and cargo residues will help to decrease the occurrence of illegal discharges in seas.

No aerial surveillance is in place for the Black Sea and the Mediterranean Sea. This is worrying as much of the Black Sea is severely polluted with oil � especially near ports and river mouths � and oil pollution along shipping lanes in the Black Sea is heavy. Hydrocarbon pollution in the French and Italian Mediterranean areas of responsibility exceeds 200 slick occurrences per year. But the data are available only at national level and not commonly reported under the Barcelona Convention. No information on Cyprus, Malta or the Mediterranean coast of Turkey is available.

In spite of being a smaller source of maritime oil pollution, major accidental oil tanker spills (i.e. those greater than 7 tonnes) have occurred sporadically in EU waters over the past decade, totalling 830.000 tonnes of spilled oil. No data were obtained for the ACs. The Commission�s Erika I and II packages � created shortly after the Erika disaster in December 1999 � aim to improve ship inspection, phase out single-hull oil tankers from EU waters by 2015, and establish a Maritime Safety Agency, which will support the Commission in stepping up maritime safety.
