Amendments to MARPOL Annex VI for Control of Emission of Ozone Depleting Substances (ODS)
The Revised MARPOL Annex VI enters into force on 1 July 2010. One of the requirements, under Regulation 12, calls for all ships to maintain a list of equipment containing ozone depleting substances (ODS) and an ODS record book. The regulation covers the recording of ODS use, deliberate and non-deliberate emission of ODS and the disposing of equipment containing ODS from ships.
The purpose of this ODS data recording is to keep a record of the condition and quantities of ODS on board a ship and serves as the basis for data collection by the relevant Flag State.
Key elements of this regulation requirement are as follows:
· Ozone depleting substances means controlled substances as defined in paragraph 1.4 of the Montreal Protocol on Substances that Deplete the Ozone Layer, 1987, and listed in Annexes A, B, C or E to the said Protocol in force at the time of application or interpretation of Annex 13 to the Revised MARPOL Annex VI.
Ozone depleting substances that may be found on board ships include but are not limited to:
· Halon 1211
· Halon 1301
· Halon 2402
· CFC-11
· CFC-12
· CFC-113
· CFC-114
· CFC-115
· The definition of ODS and the phase out dates in the Revised MARPOL Annex VI are aligned with the Montreal Protocol, 1987.
· Regulation 12 does not apply to permanently sealed equipment where there are no refrigerant charging connections or potentially removable components containing ODS.
· Each ship is to maintain a list of equipment containing ODS and also an ODS Record Book, recording each occasion of actions affecting that equipment such as servicing, maintaining, repairing or disposing of the system or the equipment containing ODS.
· Entries in the ODS Record Book are to be recorded in terms of mass (kg) of the substance and be completed without delay on each occasion with respect to the following:
· Recharge, full or partial, of equipment containing ODS
· Repair or maintenance of equipment containing ODS
· Discharge of ODS to atmosphere - deliberate and non-deliberate
· Discharge of ODS to land-based facilities
· Supply of ODS to ship
· The ODS Record Book can be a part of an existing log book or electronic recording system, as approved by the Administration.
To assist owners/operators/charterers in complying with Regulation 12, ABS has prepared templates for the List of Equipment containing ODS and the ODS Log Sheet for general use, which are available below for download.
