Revised MARPOL Annex VI
Regulation 12 – Ozone Depleting Substances

1. 1.1.

Introduction These Guidance Notes have been prepared and updated for the use of Lloyd’s Register (LR) Group Surveyors, Ship Owners and Ship Managers. They provide guidance on the requirements of MARPOL 73/78, Annex VI, Regulation 12 (hereafter referred to as Revised MARPOL Annex VI).

1.1.1. These guidance notes are divided into sections covering; the application, survey, reporting and certification of equipment under Revised MARPOL Annex VI. 1.2. Revised MARPOL Annex VI will enter into force on 01 July 2010. The original MARPOL Annex VI entered into force on 19 May 2005. Ship Owners have already undertaken verification surveys and International Air Pollution Prevention (IAPP) Certificates should be in place. Revised MARPOL Annex VI covers air pollution from ships caused by emission of ozone depleting substances. Whilst new fire-extinguishing installations containing ozone depleting halons had been prohibited as from 1 October 1994, existing system may still contain halons. Therefore, fire-fighting aspects continue to be included in these guidance notes. Revised MARPOL Annex VI, Regulation 12 applies to all ships and to fixed and floating drilling rigs and other platforms. Ships of 400 gross tons and above must be surveyed and issued with an IAPP Certificate before the ship is put into service. For existing ships of 400 gross tons and above, engaged in international voyages, the next renewal survey shall be such as to ensure that equipment, systems, fittings, arrangements and material comply fully with applicable requirements of the Revised MARPOL Annex VI. Surveys A survey is conducted to confirm that the arrangements and equipment will, with proper maintenance, be expected to remain in good condition and good working order until the next survey. Only on those occasions where the required reception facilities or necessary replacement equipment is not available locally, would items be considered for deferment.

Revised MARPOL Annex VI surveys will normally be dealt with in their entirety and not as part surveys. An Annual Survey will consist of: Verification that the certificate on board is in order. An examination of the various items of equipment to an extent which, in the surveyor’s judgement, indicates that no changes, additions or disposal has occurred since the last survey, that the equipment remains in a satisfactory condition and that the standard of maintenance is considered acceptable until the next due Survey. An Intermediate Survey will consist of: An Annual Survey plus: A thorough examination to ensure that the equipment complies with the requirements of the current Regulations and is in good working order, sufficient until the next Survey. To assist in preparing for an Annual Survey or Intermediate Survey, a provisional survey checklist has been developed.
