1.1 This document is intended to provide basic
guidance on the conduct of port State control inspections for compliance
with MARPOL Annex VI (hereinafter referred to as the Annex)
and afford consistency in the conduct of these inspections, the recognition
of deficiencies and the application of control procedures.
1.2 The regulations of MARPOL Annex VI contain
the following compliance provisions:
-
.1 an IAPP Certificate is required for all ships
of 400 GT or above engaged in international voyages. Administrations
may establish alternative appropriate measures to demonstrate the
necessary compliance in respect of ships under 400 GT engaged in international
voyages;
-
.2 new installations which contain ozone depleting
substances, other than hydro-chlorofluorocarbons, are prohibited on
or after 19 May 2005. Each ship which has rechargeable systems that
contain ozone depleting substances is required to maintain an Ozone
Depleting Substances Record Book;
-
.3 in the case of the NOx controls,
Tier I emission limits are applied to all applicable marine diesel
engines over 130 kW installed on ships constructed on or after 1 January
2000 and prior to 1 January 2011.
-
Emission limits equivalent to Tier I may apply to marine
diesel engines with a power output of more than 5,000 kW and a per
cylinder displacement at or above 90 litres installed on a ship constructed
on or after 1 January 1990 but prior to 1 January 2000 according to
regulation VI/13.7.
-
Tier II emission limits are applied to all applicable marine
diesel engines over 130 kW installed on ships constructed on or after
1 January 2011 and prior to 1 January 2016.
-
Subject to the review set forth in regulation 13.10, Tier
III emission limits are applied to all applicable marine diesel engines
over 130 kW installed on ships constructed on or after 1 January 2016.
However, while these ships are operating outside of an Emission Control
Areafootnote established for NOx control,
Tier II limits are applied.
-
Marine diesel engines which are subject to major conversion
are to be certified to the required Tier of control according to regulation
VI/13.2;
-
.4 SOx and particulate matter control
should be achieved by either:
-
.1 the sulphur content of any fuel oil used on
board ships, subject to the provisions of regulation VI/18.2, is required
not to exceed the following limits:
-
.1 4.50% m/m prior to 1 January 2012;
-
.2 3.50% m/m on and after 1 January 2012; and
-
.3 0.50% m/m on and after 1 January 2020, subject
to the review set forth in regulations VI/14.8, VI/14.9 and VI/14.10.
-
However, while ships are operating within an Emission Control
Area established for SOx and particulate matter control,
the sulphur content of fuel oil used on board ships is required not
to exceed the following limits:
-
.1 1.50% m/m prior to 1 July 2010;
-
.2 1.00% m/m on and after 1 July 2010; and
-
.3 0.10% m/m on and after 1 January 2015;
-
or,
-
.2 equivalent method as approved (regulation VI/4);
-
.5 only those incinerators installed on or after
1 January 2000 are required to comply with the associated requirements
(appendix IV to the Annex), however, the restrictions as to which
materials may be incinerated apply to all incinerators; and
-
.6 a tanker carrying crude oil is required to
have on board and implement a VOC management plan approved by the
Administration. Tanker vapour emission control systems are only required
where their fitting is specified by the relevant authority.
1.3 Chapters 1 (General), 4 (Contravention and
detention), 5 (Reporting requirements) and 6 (Review procedures) of
the Procedures for Port State Control adopted by resolution A.787(19), as amended by resolution A.882(21), also apply to these
Guidelines.
