No oil tanker of 5, 000 dwt or more carrying heavy grades of oil as cargo, irrespective of its flag, may enter or leave an EU port or offshore installation or anchor in an area under the jurisdiction of an EU Member State (including for ship-to-ship transfer operations, bunkering, crew changes, storing, etc. ), unless it is double-hulled. Single-hull oil tankers of 600 dwt or more but less than 5, 000 dwt can continue operating until the anniversary in 2008 of their delivery date. The ban is an interim measure pending the complete phasing-out of all single-hull tankers. (See also questions on Condition Assessment Scheme in Section D. )
