Data entry notes:
MEPC 75(40); Regulation 25A to Annex 1 specifies intact stability criteria for double hull tankers. Another amendment made the North West European waters a "special area" under Regulation 10 of Annex 1. The waters cover the North Sea and its approaches, the Irish Sea and its approaches, the Celtic Sea, the English Channel and its approaches and part of the North East Atlantic immediately to the West of Ireland. In special areas, discharge into the sea of oil or oily mixture from any oil tanker and ship over 400 gt is prohibited. Other special areas already designated under Annex I of MARPOL include: the Mediterranean Sea area, the Baltic Sea area, the Red Sea area, the Gulf of Aden area and the Antarctic area.
