(14)Amendments to MARPOL 73/78 adopted by the IMO on 6 March 1992 entered into force on 6 July 1993. Those measures impose double-hull or equivalent design requirements for oil tankers delivered on or after 6 July 1996 aimed at preventing oil pollution in the event of collision or stranding. Within those amendments, a phasing-out scheme for single-hull oil tankers delivered before that date took effect from 6 July 1995 requiring oil tankers delivered before 1 June 1982 to comply with the double-hull or equivalent design standards not later than 25 years and, in some cases, 30 years after the date of their delivery. Such existing single-hull oil tankers would not be allowed to operate beyond 2005 and, in some cases, 2012 unless they comply with the double-hull or equivalent design requirements of Regulation 19 of Annex I to MARPOL 73/78. For existing single-hull oil tankers delivered after 1 June 1982 or those delivered before 1 June 1982 and which have been converted to comply with the requirements of MARPOL 73/78 on segregated ballast tanks and their protective location, this deadline will be reached at the latest in 2026.
