1 Additional guidance to chapter 1
1.1 Ships are encouraged to apply regulation 43 of
MARPOL Annex I when operating in Arctic waters.
1.2Non-toxic biodegradable lubricants or
water-based systems should be considered in lubricated components located outside
the underwater hull with direct seawater interfaces, like shaft seals and slewing
seals.
2 Additional guidance to chapter
2
Category A and B ships, constructed on or after 1 January 2017 and certified to carry
noxious liquid substances (NLS), are encouraged to carry NLS identified in chapter
17, column e, as ship type 3 or identified as NLS in chapter 18 of the
International Code for the Construction and Equipment of Ships Carrying
Dangerous Chemicals in Bulk, in tanks separated from the outer shell by a
distance of not less than 760 mm.
3 Additional guidance to chapter 5
In order to minimize the risks associated with animal cargo mortalities,
consideration should be given to how animal carcasses will be managed, treated, and
stored on board when ships carrying such cargo are operating in polar waters.
Reference is made in particular to the 2012 Guidelines for the implementation of
MARPOL Annex V (resolution MEPC.219(63), as amended by resolution
MEPC.239(65)) and the 2012 Guidelines for the development of garbage management
plans (resolution MEPC.220(63)).
4 Additional guidance under other environmental
conventions and guidelines
4.1 Until the International Convention for the
Control and Management of Ships' Ballast Water and Sediments enters into
force, the ballast water management provisions of the ballast water exchange
standard, set out in regulation D-1, or the ballast water performance standard, set
out in regulation D-2 of the Convention should be considered as appropriate. The
provisions of the Guidelines for ballast water exchange in the Antarctic treaty
area (resolution MEPC.163(56)) should be taken into consideration along with
other relevant guidelines developed by the Organization
4.2 In selecting the ballast water management system,
attention should be paid to limiting conditions specified in the appendix of the
Type Approval Certificate and the temperature under which the system has been
tested, in order to ensure its suitability and effectiveness in polar waters.
4.3 In order to minimize the risk of invasive aquatic
species transfers via biofouling, measures should be considered to minimize the risk
of more rapid degradation of anti-fouling coatings associated with polar ice
operations. Reference is made in particular to the 2011 Guidelines for the
control and management of ships' biofouling to minimize the transfer of invasive
aquatic species (resolution MEPC.207(62)).
Table: Example of matters related to anti-fouling systems taken into consideration
by some ice-going ships
- (this table is used by some operators of ice-going ships)
|
|
Hull
|
Sea chest
|
| Year round operation in ice-covered polar
waters
|
|
- Abrasion resistant coating.
- Compliant with the AFS Convention. Thickness of
anti-fouling system to be decided by shipowner.
|
| Intermittent operation in ice-covered polar
waters
|
- Abrasion resistant low friction ice
coating.
- In sides, above bilge keel, max thickness of
anti-fouling system 75 μm, to protect hull between
application of anti-fouling system and next anticipated
voyage to ice-covered waters. In bottom area thickness to be
decided by shipowner. Composition of anti-fouling system
should also be decided by the shipowner.

- Compliant with the AFS Convention. Thickness of
anti-fouling system to be decided by shipowner.
|
| Category B and C vessels
|
- Compliant with the AFS Convention. Thickness of
anti-fouling system to be decided by shipowner.
|
- Compliant with the AFS Convention. Thickness of
anti-fouling system to be decided by shipowner.
