Chapter 2.4.1.1 reads as follows:
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 identification of those
components, settings and operating values of the engine which influences its NOx
emissions.
Interpretation:
This
section should be interpreted as follows: Where a NOx reducing device or system is
fitted in order to achieve compliance with regulation 13 (in accordance with paragraph
2.2.5), these should be identified in the Technical File.
Chapter 2.4.4.3 reads as follows:
On-board NOx verification procedures shall be determined by using 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.
Interpretation:
For application of this section it should be interpreted that the on-board NOx
verification procedures have been approved by the Administration taking into account
resolution MEPC.103(49) the "Guidelines for On-board NOx Verification Procedure - Direct
Measurement and Monitoring Method".
Chapter 2.4.5 reads as follows:
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:
- a definition of continuous NOx monitoring, taking into account
both steady-state and transitional operations of the engine;
- data
recording, processing and retention;
- a specification for the equipment to
ensure that its reliability is maintained during service;
- a specification
for environmental testing of the device;
- 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
- the form of the approval certificate to be issued by the Administration.
Interpretation:
For application of this section it
should be interpreted that resolution MEPC.103(49) "Guidelines for On-board NOx
Verification Procedure - Direct Measurement and Monitoring Method" defines the
guidelines as developed by the Organization.
