Regulation
13G(4) of Annex I of MARPOL 73/78 specifies the requirements
applicable to existing crude oil tankers of 20,000 tons deadweight
and above and product carriers of 30,000 tons deadweight and above
to reduce the accidental outflow of oil in the event of a collision
or stranding. Regulation 13G(7) permits
other structural or operational arrangements to be accepted as alternatives,
provided that such alternatives provide at least the same level of
protection against oil pollution in the event of collision or stranding,
and are approved by the Administration based on guidelines developed
by the Organization.
The guidelines contained herein specify the criteria by
which the acceptability of alternative arrangements should be determined.
Methods approved by the MEPC at the time of development of the guidelines
are detailed in the Appendix.
Other alternative arrangements may be approved by the MEPC
after considering their pollution prevention and safety characteristics.
A proposal for approval of a new or revised arrangement should be
submitted by an Administration and contain technical and operational
specifications and evaluation of any safety aspects.
