.1 A pre-certification survey which shall be suds as to ensure that the engine(s), as designed and equipped, complies with the NOx emission limits contained in regulation 13 of Annex VI. If this survey confirms compliance the Administration shall issue an Engine International Air Pollution Prevention (EIAPPI Certificate.
.2 An initial engine's certification survey shall be conducted on hoard of a ship before an engine is placed in service. This survey shall be suds as to ensure that the engine, an installed on board the strip, including any modification and/or adjustments since the pre-certification, if applicable, complies with the NOx emission limits contained in regulation 13 of Annex VI. This survey, as part of the ship's initial survey, may lead to either the issuance of a ship's initial International Air Pollution Prevention (IAPP) Certificate or an amendment of a ship's valid IAPP Certificate reflecting the installation of a new engine(s).
.3 Periodical and intermediate surveys, as part of a ship's surveys required by regulation 5 of Annex VI, shall be suds as to ensure the engine continues to fully comply with the provisions of this Code.
.4 An engine survey shall be conducted on hoard of a ship every time a substantial modification is made to an engine. This survey shall be such as so ensure that an engine complies with the NOx emission limits contained in regulation 13 of Annex VI.
2.1.2To comply with the survey and certification requirements discussed above, there are several alternative methods included in this Code from which she engine manufacturer, ship builder or ship owner, as applicable, cast choose to measure, calculate or test an engine for its NOx emissions, as follows:
.1 test bed testing for she pre-certification survey in accordance with chapter 5;
.2 on hoard resting for an engine not pre-certificated for a combined pre-certification and initial certification survey in accordance with the full test bed requirements of chapter 5;
3 on hoard engine parameter check method for confirmation of compliance at initial, periodical and intermediate surveys, in accordance with 6,2;
.4 on board simplified measurement method for confirmation of compliance as periodical and intermediate surveys and confirmation of pre-certified engines for initial certification surveys, in accordance with 6.3; or
.3 on hoard direct measurements and monitoring for confirmation of compliance as periodical and intermediate surveys only, in accordance with 2.3.4 to 2.3.7, 2.3.11, 2.4.4, and 5.5.1.
2.2 PROCEDURES FOR PRE-CERTIFICATION OF AN ENGINE
2.2.1Prior to installation on board, every marine diesel engine, except as allowed by 2.2.2 and 2.2.4, shall:
MLPC 39/6/I

.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 Are pre-certified by the Administration, as documented by issuance of an EIAPP Certificate.
2.2.2for 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.
2.2.3The preferred method of obtaining pre-certification for an engine is for the Administration to;
.1 witness a test of the engine on a test bed as the manufacturer's shop;
.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.
2.2.4There may be engines which, due to their size, construction and delivery schedule, can not be pre-certified on a test bed. In such cases, the engine manufacturer, ship owner or ship builder shall make application to the Administration requesting an on-board test. 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 parents engine only, but it shall not be accepted for an engine family certification.
2.2.5If the pre-certification test results show that an engine fails so 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. 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 reducing device shall be included on the EIAPP Certificate together with all other records requested by the Administration.
2.2.6For pre-certification of engines within an engine family or engine group, an EIAPP Certificate shall be issued in accordance with procedures established by she Administration to the parent engine(s) and to every member engine produced under this certification to accompany the engines throughout their marine life. The function of establishing these procedures shall not be delegated to an organization authorized loses on behalf of the Administration.
2.2.7It is a fact that she manufacturer(s) of the engines for a certain ship are not always located in the flag State of the ship. In such a case, for practical reasons, an Administration should not only issue EIAPP Certificates on its own behalf, but also, if requested, on behalf of another member Government.
