2.2 Procedures for pre-certification
of an engine
2.2.1 Prior to installation on board, every marine
diesel engine (individual engine), except as allowed by 2.2.2 and
2.2.4, shall:
-
.1 be adjusted to meet the applicable NOx emission
limit,
-
.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 family or engine group.
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 engine
group, meet the applicable NOx limit; and
-
.3 if applicable, verify that the selected parent
engine(s) is representative of an engine family or engine group.
2.2.4
Engines not pre-certified on a test-bed
-
.1 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 shipbuilder shall
make application to the Administration requesting an onboard test
(see 2.1.2.2). The applicant must
demonstrate to the Administration that the onboard test fully meets
all of the requirements of a test-bed procedure as specified in chapter
5 of this Code. 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. For engines
undergoing an onboard certification test, in order to be issued with
an EIAPP Certificate, the same procedures apply as if the engine had
been pre-certified on a test-bed, subject to the limitations given
in paragraph 2.2.4.2.
-
.2 This pre-certification survey procedure may
be accepted for an Individual Engine or for an Engine Group represented
by the Parent Engine only, but it shall not be accepted for an Engine
Family certification."
2.2.5 NOx reducing devices
-
.1 Where a NOx-reducing device is to be
included within the EIAPP certification, it must be recognized as a component of
the engine, and its presence shall be recorded in the engine's Technical File. The
applicable test procedure shall be performed and the combined
engine/NOx-reducing device shall be approved and pre-certified by
the Administration taking into account Guidelines developed by the
Organizationfootnote. However, the pre-certification in accordance with the procedure
not involving the testing for the combined engine/NOX-reducing device
on a test bed as given by the Guidelines developed by the Organization is subject
to the limitations given in paragraph 2.2.4.2.
-
.2 In those cases where a NOx reducing
device has been fitted due to failure to meet the required emission
value at the pre-certification test, in order 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
applicable NOx emission limit. However, in this case, the
assembly may be re-tested in accordance with the simplified measurement
method in accordance with 6.3. In
no case shall the allowances given in 6.3.11 be
granted.
-
.3 Where, in accordance with 2.2.5.2, the effectiveness
of the NOx reducing device is verified by use of the simplified
measurement method, that test report shall be added as an adjunct
to the pre-certification test report that demonstrated the failure
of the engine alone to meet the required emission value. Both test
reports shall be submitted to the Administration, and test report
data, as detailed in 2.4.1.5, covering
both tests shall be included in the engine’s technical file.
-
.4 The simplified measurement method used as part
of the process to demonstrate compliance in accordance with 2.2.5.2
may only be accepted in respect of the engine and NOx reducing
device on which its effectiveness was demonstrated, and it shall not
be accepted for engine family or engine group certification.
-
.5 In both cases as given in 2.2.5.1 and 2.2.5.2,
the NOx reducing device shall be included on the EIAPP
Certificate together with the emission value obtained with the device
in operation and all other records as required by the Administration.
The engine’s technical file shall also contain onboard NOx verification
procedures for the device to ensure it is operating correctly.
-
.6 Notwithstanding 2.2.5.3 and 2.2.5.4, a NOx reducing
device may be approved by the Administration taking into account guidelines
to be developed by the Organization.
2.2.6 Where, due to changes of component design,
it is necessary to establish a new engine family or engine group but
there is no available parent engine the engine builder may apply to
the Administration to use the previously obtained parent engine test
data modified at each specific mode of the applicable test cycle so
as to allow for the resulting changes in NOx emission values.
In such cases, the engine used to determine the modification emission
data shall correspond in accordance with the requirements of 4.4.6.1, 4.4.6.2 and 4.4.6.3 to the previously
used parent engine. Where more than one component is to be changed
the combined effect resulting from those changes is to be demonstrated
by a single set of test results.
2.2.7 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.
2.2.8 Issue of certification by the Administration
of the country in which the engine is built
-
.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 applicable requirements of regulation 13 are complied with pursuant
to this Code, the Administration of the country in which the engine
is manufactured shall issue or authorize the issuance of the EIAPP
Certificate.
-
.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.
-
.3 A certificate so issued shall contain a statement
to the effect that it has been issued at the request of the Administration.
2.2.9 Guidance in respect of the pre-certification
survey and certification of marine diesel engines, as described in chapter 2 of this Code, is given in the relevant
flowchart in appendix 2 of this Code.
Where discrepancies exist, the text of chapter
2 takes precedence.
2.2.10 A model form of an EIAPP Certificate is
attached as appendix 1 to this Code.
