1 Except as provided in paragraph 4 of this regulation, shipboard
incineration shall be allowed only in a shipboard incinerator.
2 Shipboard incineration of the following substances shall be prohibited:
-
.1 residues of cargoes subject to Annex
I, II or III or related contaminated packing materials;
-
.2 polychlorinated biphenyls (PCBs);
-
.3 garbage, as defined by Annex
V, containing more than traces of heavy metals;
-
.4 refined petroleum products containing halogen compounds;
-
.5 sewage sludge and sludge oil neither of which is generated on board
the ship; and
-
.6 exhaust gas cleaning system residues.
3 Shipboard incineration of polyvinyl chlorides (PVCs) shall be prohibited,
except in shipboard incinerators for which IMO Type Approval Certificatesfootnote have been issued.
4 Shipboard incineration of sewage sludge and sludge oil generated during
normal operation of a ship may also take place in the main or auxiliary power plant or
boilers, but in those cases, shall not take place inside ports, harbours or estuaries.
5 Nothing in this regulation either:
-
.1 affects the incineration at sea prohibitions of the Convention on
the Prevention of Marine Pollution by Dumping of Wastes and Other Matter, 1972, as
amended, and the 1996 Protocol thereto, or other requirements thereof,
or
-
.2 precludes the development, installation and operation of
alternative design shipboard thermal waste treatment devices that meet or exceed
the requirements of this regulation.
6.1 Except as provided in paragraph 6.2 of this regulation, each
incinerator on a ship constructed on or after 1 January 2000 or incinerator that is
installed on board a ship on or after 1 January 2000 shall meet the requirements
contained in appendix
IV to this Annex. Each incinerator subject to this paragraph shall be approved
by the Administration taking into account the standard specification for shipboard
incinerators developed by the Organization;footnote
6.2 The Administration may allow exclusion from the application of
paragraph 6.1 of this regulation to any incinerator installed on board a ship before 19
May 2005, provided that the ship is solely engaged in voyages within waters subject to
the sovereignty or jurisdiction of the State the flag of which the ship is entitled to
fly.
7 Incinerators installed in accordance with the requirements of paragraph
6.1 of this regulation shall be provided with a manufacturer’s operating manual, which
is to be retained with the unit and which shall specify how to operate the incinerator
within the limits described in paragraph 2 of appendix IV of
this Annex.
8 Personnel responsible for the operation of an incinerator installed in
accordance with the requirements of paragraph 6.1 of this regulation shall be trained to
implement the guidance provided in the manufacturer’s operating manual as required by
paragraph 7 of this regulation.
9 For incinerators installed in accordance with the requirements of
paragraph 6.1 of this regulation the combustion chamber gas outlet temperature shall be
monitored at all times the unit is in operation. Where that incinerator is of the
continuous-feed type, waste shall not be fed into the unit when the combustion chamber
gas outlet temperature is below 850°C. Where that incinerator is of the batch-loaded
type, the unit shall be designed so that the combustion chamber gas outlet temperature
shall reach 600°C within five minutes after start-up. and will thereafter stabilize at a
temperature not less than 850°C.
