The International Maritime Organisations Marine Environment
Protection Committee (MEPC) adopted a revised MARPOL 73/78 Annex II
Regulations for the Control of Pollution by Noxious Liquid
Substances in Bulk in 2004 and will enter into force 1 January 2007
and will apply to both new and existing ships.
This revised Annex uses a new four-category pollution category
system for noxious liquid substances; the exting A, B, C and D
category system will become X,Y and Z .
What are the amendments?
The revised Annex includes a number of other significant
changes. Improvements in ship technology, such as efficient
stripping techniques, have made it possible to significantly lower
permitted discharge levels of certain products and these have been
incorporated into Annex II. For ships constructed on or after
January 1, 2007 the maximum permitted residue in the tank and its
associated piping left after discharge will be set at a maximum of
75 litres for products in categories X, Y and Z - compared with
previous limits which set a maximum of 100, 300 or 900 litres with
a 50 litre tolerance, depending on the product category and age of
the ship.
In addition to the revision of Annex II, the marine pollution
hazards of thousands of chemicals have been re-evaluated giving a
resultant hazard profile which indexes the substance according to
its bio-accumulation, bio-degradation, acute toxicity, chronic
toxicity, long-term health effects, and effects on marine wildlife
and on benthic habitats.
As a result of the hazard evaluation process and the new
categorisation system, vegetable oils which were previously
categorised as being unrestricted will now be required to be
carried in chemical tankers.
How does Lloyds Register help?
Identification of what cargoes can be carried on your ship(s)
when the new requirements enter into force
Using the ship parameters held on record for vessels we have
previously issued with an NLS certificate or Certificate of
Fitness, we can determine which cargoes could be carried after
January 1, 2007.
If you have not previously had NLS certification from Lloyds
Register, then on completion of a questionnaire we can still
provide you with details of the cargoes that could be carried after
January 1, 2007.
If you have any proposed modifications to your vessel, we are
able to analyse these proposals in order to determine which
additional cargoes could be carried were these changes to be
undertaken.
Approval of Procedures and Arrangements Manuals
Procedures and Arrangements Manuals for all ships carrying
pollution category X, Y, or Z cargoes will require revision and
re-approval before January 1, 2007. Lloyds Register is authorised
by numerous administrations to carry out this approval on their
behalf, and is also able to offer guidance in the correct
compilation of these manuals.
Advisory services
After January 1, 2007, it may be a more viable option for
instance to convert a product tanker to a chemical tanker. Lloyds
Register Consultancy Services Group can offer guidance regarding
the necessary modifications. The Statutory and Structures Services
surveyors can approve the arrangements on behalf of many
administrations, and issue certification and cargo lists for
trading purposes.
