For the selected memo regulation

MARPOL 73/78 Annex VI Regulations for the prevention of Air Pollution from ships will enter into force on 19 May 2005, and includes many new aspects related to design of ships, but even more related to operational issues. The intention with this paper is to highlight some of the most important aspects of MARPOL Annex VI for the guidance of Ship owners and Managers, as well as DNV surveyors.

Annex VI in general

The adoption of MARPOL Annex VI has followed some years of debate within organisations. At the same time IMO Technical code on the Control of Emissions of Nitrogen Oxides from Marine Diesel Engines was adopted. MARPOL Annex VI and the Technical Code have retroactive requirements for diesel engines 130 KW and above installed on ships keel-laid on or after 1 January 2000, and Incinerators installed onboard on or after 1 January 2000.

MARPOL Annex VI will apply to all ships, fixed and floating drilling rigs and other platforms from 19 May 2005, but the certification requirements are depending on size of the vessel and time of periodical survey. Ships of 400 gross tons and above engaged in international voyages involving countries that have ratified the conventions, or ships flying the flag of those countries, are required to have an International Air Pollution Prevention Certificate (IAPP Certificate).

This certificate must be on board at delivery for a ship constructed (keel laid) after 19 May 2005. For ships constructed before this date, the IAPP certificate must be on board at the first scheduled dry-docking after 19 May 2005, but not later than 19 May 2008.

The IAPP certificate will be issued following an initial survey carried out by the Flag Administration or by a recognised organization (e.g. Det Norske Veritas) on behalf of the Flag Administration, confirming compliance with MARPOL Annex VI. For ships with the flag of an Administration that have not yet ratified Annex VI, a Certificate of Compliance with Annex VI may be issued by DNV.

Annex VI also requires diesel engines (as described above) to carry individual certificates with regard to NOx emissions, named Engine International Air Pollution Prevention (EIAPP) Certificates.

Annex VI requires that every ship of 400 gross tonnage or above and every fixed and floating drilling rig and other platforms shall be subject to the following surveys:

- An initial survey before the ship is put into service or before the IAPP Certificate is issued for the first time.

- Periodical surveys at intervals specified by the Administration, but not exceeding five years.

- A minimum of one intermediate survey during the period of validity of the certificate.

In the case of ships of less than 400 gross tons, the Administration may establish appropriate measures in order to ensure that Annex VI is complied with.

The Administration shall arrange for unscheduled inspections during the period of validity of the certificate. If the Administration establishes mandatory annual surveys, these unscheduled inspections shall not be obligatory, and for this purpose DNV has so far considered that all Administrations will ...
