50TH SESSION OF IMO MARINE ENVIRONMENT PROTECTION
Delegates to the International Maritime Organizationís (IMO) Marine
Environment Protection Committee meeting, which took place from 1-4 December 2003 in London,
agreed to amend the International Convention for the Prevention of Pollution from Ships
by phasing out single-hull oil tankers by 2010. Other measures agreed to include an
extended application of the Condition Assessment Scheme (CAS) for tankers and a new
regulation banning the carriage of Heavy Grade Oil (HGO) in single-hull tankers
(MARPOL 73/78). The amendments are expected to enter into force on 5 April 2005.
Under a revised regulation 13G of Annex I of MARPOL, the final
phasing-out date for
Category 1 tankers (pre-MARPOL tankers) has been brought forward to 2005
from 2007. The final phasing-out date for category 2 and 3 tankers (MARPOL tankers and
smaller tankers) was brought forward to 2010, from 2015. In addition, the CAS is to be made
applicable to all single-hull tankers of 15 years or older. Previously it was applicable to
all Category 1 vessels continuing to trade after 2005 and all Category 2 vessels after 2010.
In order to prevent oil pollution from HGO-carrying oil tankers, delegates
adopted a new
MARPOL regulation that bans the carriage of HGO in single-hull tankers of
5,000 tons dwt
and above after the date of entry into force, and in single-hull oil
tankers of 600 tons dwt and above but less than 5,000 tons dwt, not later than the anniversary of their
delivery date in 2008.
