2.2 Procedures for pre-certification of an engine

  2.2.1 Prior to installation on board, every marine diesel engine, except as allowed by 2.2.2 and 2.2.4, shall:

  • .1 be adjusted to meet the applicable NOx emission limits,

  • .2 have its NOx emissions measured on a test-bed in accordance with the procedures specified in chapter 5 of this Code, and

  • .3 be pre-certified by the Administration, as documented by issuance of an EIAPP Certificate.

  2.2.2 For the pre-certification of serially manufactured engines, depending on the approval of the Administration, the engine family or the engine group concept may be applied (see chapter 4). In such a case, the testing specified in 2.2.1.2 is required only for the parent engine(s) of an engine group or engine family.

  2.2.3 The method of obtaining pre-certification for an engine is for the Administration to:

  • .1 certify a test of the engine on a test-bed;

  • .2 verify that all engines tested, including, if applicable, those to be delivered within an engine family or group, meet the NOx limits; and

  • .3 if applicable, verify that the selected parent engine(s) is representative of an engine family or engine group.

  2.2.4 There are engines which, due to their size, construction and delivery schedule, cannot be pre-certified on a test-bed. In such cases, the engine manufacturer, shipowner or ship builder shall make application to the Administration requesting an on-board test (see 2.1.2.2). The applicant must demonstrate to the Administration that the on-board test fully meets all of the requirements of a test bed procedure as specified in chapter 5 of this Code. Such a survey may be accepted for one engine or for an engine group represented by the parent engine only, but it shall not be accepted for an engine family certification. In no case shall an allowance be granted for possible deviations of measurements if an initial survey is carried out on board a ship without any valid pre-certification test.

  2.2.5 If the pre-certification test results show that an engine fails to meet the NOx emission limits as required by regulation 13 of Annex VI, a NOx-reducing device may be installed. This device, when installed on the engine, must be recognized as an essential component of the engine and its presence will be recorded in the engine's technical file. To receive an EIAPP Certificate for this assembly, the engine, including the reducing device, as installed, must be re-tested to show compliance with the NOx emission limits. However, in this case, the assembly may be re-tested in accordance with the simplified measurement method addressed in 6.3. The NOx-reducing device shall be included on the EIAPP Certificate together with all other records requested by the Administration. The engine's technical file shall also contain on-board NOx verification procedures for the device to ensure it is operating correctly.

  2.2.6 For pre-certification of engines within an engine family or engine group, an EIAPP Certificate shall be issued in accordance with procedures established by the Administration to the parent engine(s) and to every member engine produced under this certification to accompany the engines throughout their life whilst installed on ships under the authority of that Administration.

  2.2.7.1 When an engine is manufactured outside the country of the Administration of the ship on which it will be installed, the Administration of the ship may request the Administration of the country in which the engine is manufactured to survey the engine. Upon satisfaction that the requirements of regulation 13 of Annex VI are complied with pursuant to this NOx Technical Code, the Administration of the country in which the engine is manufactured shall issue or authorize the issuance of the EIAPP Certificate.

  2.2.7.2 A copy of the certificate(s) and a copy of the survey report shall be transmitted as soon as possible to the requesting Administration.

  2.2.7.3 A certificate so issued shall contain a statement to the effect that it has been issued at the request of the Administration.

  2.2.8 A flow chart providing guidance for compliance with the requirements of a pre-certification survey for marine diesel engines intended for installation on board of ships is provided in figure 1 of appendix 2 of this Code.

  2.2.9 A model form of an EIAPP Certificate is attached as appendix 1 to this Code.
