These Guidelines are intended to assist an Administration
by providing an outline of the information to be submitted to the
Organization for inclusion in the notification of certification of
an Approved Method as required under regulation 13.7.1 of MARPOL Annex VI.
2
INFORMATION TO BE SUBMITTED
TO THE ORGANIZATION
2.1
Contents of the information
to be submitted
The notification to the Organization of the certification
of an Approved Method should include, but is not limited to:
-
.1 the certification reference of the Approved
Method together with details of the Approved Method;
-
.2 a copy of the Approved Method File, or where
that is not possible, a sample of the File taking into account paragraph
2.2;
-
.3 criteria for identification of the engines
to which an Approved Method applies as specified in paragraph 2.3;
and
-
.4 Approved Method contact point.
2.2
A copy or sample of the
Approved Method File
2.2.1 In accordance with paragraph 7.4 of the NOX Technical Code 2008
, the Approved
Method File is an integral part of any Approved Method and should
be authenticated by the application of the stamp of the certifying
Administration. A copy of this Approved Method File should be included
in the notification to the Organization.
2.2.2 However, in cases where, due to differences
between individual engines at the time of manufacture, it is not possible
to provide a copy of the Approved Method File as being representative
of all engines to be covered by the specific Approved Method, a sample
of the Approved Method File should instead be included in the notification
to the Organization. This sample Approved Method File should contain
sufficient detail that will make it possible to correlate with the
actual Approved Method File to be supplied for individual engines.
2.2.3 In cases where a sample of the Approved
Method File is included, the procedure for approval of individual
Approved Method Files should be included in the notification. In all
cases the authentication of the Approved Method File should be undertaken
by the certifying Administration.
2.2.4 The Approved Method File should also include
a description of the engine's onboard verification procedure, in accordance
with paragraph 7.5 of the NOX Technical
Code 2008
.
2.2.5 A list of the onboard record keeping requirements
for the Approved Method should be included.
2.3
Criteria for the identification
of an engine to which an Approved Method applies
2.3.1 Criteria for the identification of an engine
to which a particular Approved Method applies should be included.
This should also cover those cases where the current engine condition
differs from the original engine condition at the time of manufacturing
due to modifications either at the time of installation or subsequent
modifications over its service life.
2.3.2 If the Approved Method developer knows the
current condition of a particular engine, those parameters should
be listed in the Approved Method File and the engine or engines to
which it applies should be identified by engine make, type and serial
number in the Approved Method File.
2.3.3 However, the developer of an Approved Method
will usually not know the actual current engine condition. Consequently,
the criteria which define an engine will relate to the original engine
condition at the time of manufacturing. The criteria which define
the applicability of a particular Approved Method should include the
following items:
-
.1 manufacturer/licensee, engine type and model;
-
.2 application cycle(s) e.g. E2, E3, D2 or C1,
as specified in chapter 3 of the NOX Technical
Code 2008 as appropriate;
-
.3 rated power (kW) and rated speed (rpm) as given
on the nameplate or as modified by approved re-rating:
-
.1 the applicable power output/rated speed range
is to be clearly shown whether these represent a "line" or a "box",
the exception or inclusion on the boundary and any exceptions either
inside or outside that boundary; and
-
.2 in addition, any potentially necessary calculation
processes (for example between horsepower (metric/imperial) and kW)
including the rounding method is to be clearly specified;
-
.4 NOX critical components and how
their identity should be established. Where there is a combination
of components, it should be described how those are interrelated;
-
.5 NOX critical settings or operating
values and how those values should be established. Where there are
combinations of settings, it should be described how these are interrelated.
In addition, any potentially necessary calculation processes (for
example to bring Pmax or Pcomp to the ISO specified condition), including
the rounding method, is to be clearly specified; and
-
.6 any other specific points which relate to engines
to which the Approved Method applies.
