General requirements
1 The sulphur content of fuel oil used or carried for use on board a ship
shall not exceed 0.50% m/m.
2 The worldwide average sulphur content of residual fuel oil supplied for
use on board ships shall be monitored taking into account the guidelines developed by
the Organization.footnote
Requirements within emission control areas
3 For the purpose of this regulation, an emission control area shall be any
sea area, including any port area, designated by the Organization in accordance with the
criteria and procedures set forth in appendix III to
this Annex. The emission control areas under this regulation are:
-
.1 the Baltic Sea area as defined in regulation 1.11.2 of Annex I of the present Convention;
-
.2 the North Sea area as defined in regulation 1.14.6 of Annex V of the present Convention;
-
.3 the North American Emission Control Area, which means the area
described by the coordinates provided in appendix
VII to this Annex; and
-
.4 the United States Caribbean Sea Emission Control Area, which means
the area described by the coordinates provided in appendix
VII to this Annex.
4 While a ship is operating within an emission control area, the sulphur
content of fuel oil used on board that ship shall not exceed 0.10% m/m.
5 The sulphur content of fuel oil referred to in paragraph 1 and paragraph
4 of this regulation shall be documented by its supplier as required by regulation 18
of this Annex.
6 Those ships using separate fuel oils to comply with paragraph 4 of this
regulation and entering or leaving an emission control area set forth in paragraph 3 of
this regulation shall carry a written procedure showing how the fuel oil changeover is
to be done, allowing sufficient time for the fuel oil service system to be fully flushed
of all fuel oils exceeding the applicable sulphur content specified in paragraph 4 of
this regulation prior to entry into an emission control area. The volume of low sulphur
fuel oils in each tank as well as the date, time and position of the ship when any fuel
oil changeover operation is completed prior to the entry into an emission control area
or commenced after exit from such an area shall be recorded in such logbook or
electronic record bookfootnote as prescribed by the Administration.
7 During the first 12 months immediately following entry into force of an
amendment designating a specific emission control area under paragraph 3 of this
regulation, ships operating in that emission control area are exempt from the
requirements in paragraphs 4 and 6 of this regulation and from the requirements of
paragraph 5 of this regulation insofar as they relate to paragraph 4 of this regulation.
In-use and onboard fuel oil sampling and testing
8 If the competent authority of a Party requires the in-use or onboard
sample to be analysed, it shall be done in accordance with the verification procedure
set forth in appendix VI to this Annex to determine whether the fuel oil being used or
carried for use on board meets the requirements in paragraph 1 or paragraph 4 of this
regulation. The in-use sample shall be drawn taking into account the guidelines
developed by the Organization.footnote The onboard sample shall be drawn taking into account the
guidelines developed by the Organization.footnote
9 The sample shall be sealed by the representative of the competent
authority with a unique means of identification installed in the presence of the ship’s
representative. The ship shall be given the option of retaining a duplicate sample.
In-use fuel oil sampling point
10 For each ship subject to regulations 5
and 6 of
this Annex, sampling point(s) shall be fitted or designated for the purpose of taking
representative samples of the fuel oil being used on board the ship taking into account
the guidelines developed by the Organization.footnote
11 For a ship constructed before 1 April 2022, the sampling point(s)
referred to in paragraph 10 shall be fitted or designated not later than the first
renewal survey as identified in regulation 5.1.2 of this Annex on or after 1 April 2023.
12 The requirements of paragraphs 10 and 11 above are not applicable to a
fuel oil service system for a low-flashpoint fuel for combustion purposes for propulsion
or operation on board the ship.
13 The competent authority of a Party shall, as appropriate, utilize the
sampling point(s) which is(are) fitted or designated for the purpose of taking
representative sample(s) of the fuel oil being used on board in order to verify that the
fuel oil complies with this regulation. Taking fuel oil samples by the competent
authority of the Party shall be performed as expeditiously as possible without causing
the ship to be unduly delayed.
