ANNEX VI OF MARPOL 73/78 REGULATION 13 Nitrogen Oxides (NOX)

1  a)   This regulation shall apply to:

i)          each diesel engine with a power output of more than 130 kW which is installed on a ship constructed on or after 1 January 2000; and

ii)         each diesel engine with a power output of more than 130 kW which undergoes a major con­version on or after 1 January 2000.

     b)    This regulation does not apply to:

i)          emergency diesel engines, en­gines installed in lifeboats and any device or equipment intended to be used solely in case of emer­gency; and

ii)   engines installed on ships solely engaged in voyages within waters subject to the sovereignty or jurisdiction of the State the flag of which the ship is entitled to fly, provided that such engines are subject to an alternative NOx control measure established by the Administration.

    c)   Notwithstanding the provisions of subparagraph (a) of this paragraph, the Administration may allow exclusion from the application of this regulation to any diesel engine which is installed on a ship constructed, or on a ship which undergoes a major conversion, before the date of entry into force of the present Protocol, provided that the ship is solely engaged in voyages to ports or offshore terminals within the State the flag of which the ship is entitled to fly.

2  a)    For the purpose of this regulation, “major conversion” means a modificat­ion of an engine where:

i)          the engine is replaced by a new engine built on or after 1 January 2000, or

ii)         any substantial modification, as defined in the NOx Technical Code, is made to the engine, or

 

INTERIM GUIDELINES FOR THE APPLICATION OF THE NOxTECHNICAL CODE

1.    The Conference of Parties to the International Convention for the Prevention of Pollution from Ships, 1973, as modified by the Protocol of 1978 relating thereto, held from 15 to 26 September 1997 in conjunction with the Marine Environment Protection Committee's fortieth session, adopted, in Conference Resolution 2, the Technical Code on Control of Emission of Nitrogen Oxides from Marine Diesel Engines (The NOx Technical Code). 

2.    The purpose of the NOx Technical Code is to establish mandatory procedures for the testing, survey and certification of marine diesel engines which will enable engine manufacturers, shipowners and Administrat­ions to ensure that all applicable marine diesel engines comply with the relevant limits for emission values of NOx as specified in regulation 13 of Annex VI to MARPOL 73/78. 

3.    It is noted that regulation 13 of MARPOL Annex VI is intended to be applied to diesel engines installed on ships constructed on or after 1 January 2000. While the requirements of the regulation could not be enforced before the entry into force of the Protocol of 1997, it should be clearly understood that engines installed on ships constructed on or after 1 January 2000 or engines which undergo a major conversion on or after 1 January 2000 will have to meet these requirements once the Protocol enters into force. 

4.    To allow uniform application of the Code, and to assist Administrations in certifying engines in accordance with it, prior to the date of entry into force of Annex VI, the guidelines following are recommended to be used.

 

Interim Guidelines For The Application Of The NOxTechnical Code

1.    Each engine which will become, retrospectively, subject to the provisions of regulation 13 of Annex VI of MARPOL 73/78 upon its entry into force, should be certified in accordance with the requirements of the NOx Technical Code. 

2.    Pending entry into force of Annex VI and upon satisfactory compliance with the Code requirements, a “Statement of Compliance” with the NOx Technical Code should be issued by the flag State Administration, or an organization acting on behalf of that Administration. Such a Statement of Com­pliance should contain as a minimum the information as required by appendix 1 of the NOx Technical Code. 

3.    The Statement of Compliance is intended as an interim measure pending issuance of the Engine International Air Pollution Prevention (EIAPP) and/or International Air Pollution Prevention (IAPP) Certificate upon entry into force of Annex VI. 

4.    Administrations are urged to take into consideration the Statement of Compliance when issuing certificates in accordance with Annex VI, whether or not the Statement of Compliance was issued by their Administrat­ion, or organizations acting on their behalf, or by other Governments.
