2.4.1 To enable an Administration to perform the
engine surveys described in 2.1, the
technical file required by 2.3.6 shall,
at a minimum, contain the following information:
-
.1 identification of those components, settings
and operating values of the engine which influence its NOx emissions;
-
.2 identification of the full range of allowable
adjustments or alternatives for the components of the engine;
-
.3 full record of the relevant engine's performance,
including the engine's rated speed and rated power;
-
.4 a system of on-board NOx verification
procedures to verify compliance with the NOx emission limits
during on-board verification surveys in accordance with chapter 6;
-
.5 a copy of the test report required in 5.10;
-
.6 if applicable, the designation and restrictions
for an engine which is a member of an engine group or engine family;
-
.7 specifications of those spare parts/components
which, when used in the engine, according to those specifications,
will result in continued compliance of the engine with the NOx emission
limits; and
-
.8 the EIAPP Certificate, as applicable.
2.4.2 To ensure that engines are in compliance
with regulation 13 of Annex
VI after installation, each engine with an EIAPP Certificate shall
be checked at least once prior to issuance of the IAPP Certificate.
Such check can be done using the on-board NOx verification
procedures specified in the engine's technical file or one of the
other methods if the owner's representative does not wish to check
using the on-board NOx verification procedures.
2.4.3 As a general principle, on-board NOx verification
procedures shall enable a surveyor to easily determine if an engine
has remained in compliance with regulation
13 of Annex VI. At the same time, it shall not be so burdensome
as to unduly delay the ship or to require in-depth knowledge of the
characteristics of a particular engine or specialist measuring devices
not available on board.
2.4.4 On-board NOx verification procedures
shall be determined by using one of the following methods:
-
.1 engine parameter check in accordance with 6.2 to verify that an engine's component, setting
and operating values have not deviated from the specifications in
the engine's technical file;
-
.2 simplified measurement method in accordance
with 6.3; or
-
.3 the direct measurement and monitoring method
in accordance with 2.3.4, 2.3.5. 2.3.7, 2.3.8,
2.3.11, and 5.5.
2.4.5 When a NOx monitoring and recording
device is specified as on-board NOx verification procedures,
such device shall be approved by the Administration based on guidelines
to be developed by the Organization. These guidelines shall include,
but are not limited to, the following items:
-
.1 a definition of continuous NOx monitoring,
taking into account both steady-state and transitional operations
of the engine;
-
.2 data recording, processing and retention;
-
.3 a specification for the equipment to ensure
that its reliability is maintained during service;
-
.4 a specification for environmental testing of
the device;
-
.5 a specification for the testing of the equipment
to demonstrate that it has a suitable accuracy, repeatability and
cross sensitivity compared with the applicable sections of this Code;
and
-
.6 the form of the approval certificate to be
issued by the Administration.
2.4.6 When considering what on-board NOx verification
procedures should be included in an engine's technical file to verify
whether an engine complies with the NOx emission limits
during any of the required on-board verification surveys, subsequent
to the issuance of an IAPP Certificate, an engine manufacturer or
the shipowner may choose any of the three methods for on board NOx verification
procedures specified in 6.1.
