MARPOL Annex I Reg 20: existing oil tankers

MARPOL Annex I Regulation 20 carries the requirements for existing oil tankers that do not meet the double hull standard of Regulation 19 . It descends from Regulation 13G of the original Annex I, introduced by MEPC.52(32) on 6 March 1992 and accelerated by MEPC.95(46) on 27 April 2001 and MEPC.111(50) on 4 December 2003, and took its current number in the revised Annex I adopted by MEPC.117(52), in force from 1 January 2007.

The full article will set out the categories of tanker, the phase-out dates, the Condition Assessment Scheme, and the cross-references to the raking damage assumption, which MEPC.248(66) renumbered from Regulation 28.6 to 28.7 on 1 January 2016.
