Requirements for the Inventory
3.1
Scope of the Inventory
The Inventory consists of:
- Part I: Materials contained in ship
structure or equipment;
- Part II: Operationally generated
wastes; and
- Part III: Stores.
3.2
Materials to be listed in the Inventory
3.2.1 Appendix 1 of these guidelines (Items
to be listed in the Inventory of Hazardous Materials), provides information on the
hazardous materials that may be found on board a ship. Materials set out in appendix
1 should be listed in the Inventory. Each item in appendix 1 of these guidelines is
classified under tables A, B, C or D, according to its properties:
- .1 table A comprises the materials
listed in appendix 1 of the Convention;
- .2 table B comprises the materials
listed in appendix 2 of the Convention;
- .3 table C (Potentially hazardous
items) comprises items which are potentially hazardous to the environment
and human health at ship recycling facilities; and
- .4 table D (Regular consumable
goods potentially containing hazardous materials) comprises goods which are
not integral to a ship and are unlikely to be dismantled or treated at a
ship recycling facility.
3.2.2 Tables A and B correspond to part I
of the Inventory. Table C corresponds to parts II and III and table D corresponds to
part III.
3.2.3 For loosely fitted equipment, there
is no need to list this in part I of the Inventory. Such equipment which remains on
board when the ship is recycled should be listed in part III.
3.2.4 Those batteries containing lead acid
or other hazardous materials that are fixed in place should be listed in part I of
the Inventory. Batteries that are loosely fitted, which includes consumer batteries
and batteries in stores, should be listed in part III of the Inventory.
3.2.5 Similar materials or items that
contain hazardous materials that potentially exceed the threshold value can be
listed together (not individually) on the IHM with their general location and
approximate amount specified there (hereinafter referred to as "bulk listing"). An
example of how to list those materials and items is shown in row 3 of table 1 of
appendix 3.
3.3
Exemptions – Materials not required to be listed in the Inventory
3.3.1 Materials listed in Table B that are
inherent in solid metals or metal alloys, such as steels, aluminium, brasses,
bronzes, plating and solders, provided they are used in general construction, such
as hull, superstructure, pipes or housings for equipment and machinery, are not
required to be listed in the Inventory.
3.3.2 Although electrical and electronic
equipment is required to be listed in the Inventory, the amount of hazardous
materials potentially contained in printed wiring boards (printed circuit boards)
installed in the equipment does not need to be reported in the Inventory.
3.4
Standard format of the Inventory of Hazardous Materials
The Inventory should be developed on the basis of the standard format set
out in appendix 2 of these guidelines: Standard format of the Inventory of Hazardous
Materials. Examples of how to complete the Inventory are provided for guidance
purposes only.
3.5
Revision to threshold values
Revised threshold values in tables A and B of appendix 1 should be used
for IHMs developed or updated after the adoption of the revised values and need not
be applied to existing IHMs and IHMs under development. However, when materials are
added to the IHM, such as during maintenance, the revised threshold values should be
applied and recorded in the IHM.

Requirements for development of the Inventory
4.1
Development of part I of the Inventory for new shipsfootnote
4.1.1 Part I of the Inventory for new
ships should be developed at the design and construction stage.
4.1.2 Checking of materials
listed in table A
During the development of the Inventory (part I), the presence of
materials listed in table A of appendix 1 should be checked and confirmed; the
quantity and location of table A materials should be listed in part I of the
Inventory. If such materials are used in compliance with the Convention, they should
be listed in part I of the Inventory. Any spare parts containing materials listed in
table A are required to be listed in part III of the Inventory.
4.1.3
Checking of materials listed in table B
If materials listed in table B of appendix 1 are present in products
above the threshold values provided in table B, the quantity and location of the
products and the contents of the materials present in them should be listed in part
I of the Inventory. Any spare parts containing materials listed in table B are
required to be listed in part III of the Inventory.
4.1.4
Process for checking of materials
The checking of materials as provided in paragraphs 4.1.2 and 4.1.3 above
should be based on the Material Declaration furnished by the suppliers in the
shipbuilding supply chain (e.g. equipment suppliers, parts suppliers, material
suppliers).
4.2
Development of part I of the Inventory for existing ships
4.2.1 In order to achieve comparable results
for existing ships with respect to part I of the Inventory, the following procedure
should be followed:
- .1 collection of necessary
information;
- .2 assessment of collected
information;
- .3 preparation of visual/sampling
check plan;
- .4 onboard visual check and
sampling check; and
- .5 preparation of part I of the
Inventory and related documentation.
4.2.2 The determination of hazardous
materials present on board existing ships should, as far as practicable, be
conducted as prescribed for new ships, including the procedures described in
sections 6 and 7 of these guidelines. Alternatively, the procedures described in
this section may be applied for existing ships, but these procedures should not be
used for any new installation resulting from the conversion or repair of existing
ships after the initial preparation of the Inventory.
4.2.3 The procedures described in this
section should be carried out by the shipowner, who may draw upon expert assistance.
Such an expert or expert party should not be the same as the person or organization
authorized by the Administration to approve the Inventory).
4.2.4 Reference is made to appendix 4 (Flow
diagram for developing part I of the Inventory for existing ships) and appendix 5
(Example of development process for part I of the Inventory for existing ships.
4.2.5
Collection of necessary information (step 1)
The shipowner should identify, research, request and procure all
reasonably available documentation regarding the ship. Information that will be
useful includes maintenance, conversion and repair documents; certificates, manuals,
ship's plans, drawings and technical specifications; product information data sheets
(such as Material Declarations); and hazardous material inventories or recycling
information from sister ships. Potential sources of information could include
previous shipowners, the ship builder, historical societies, classification society
records and ship recycling facilities with experience working with similar
ships.
4.2.6
Assessment of collected information (step 2)
The information collected in step 1 above should be assessed. The assessment should
cover all materials listed in table A of appendix 1; materials listed in table B
should be assessed as far as practicable. The results of the assessment should be
reflected in the visual/sampling check plan.
4.2.7 Preparation of visual/sampling check plan (step
3)
4.2.7.1 To specify the materials listed in
appendix 1 of these guidelines, a visual/sampling check plan should be prepared
taking into account the collated information and any appropriate expertise. The
visual/sampling check plan should be based on the following three lists:
- .1 List of equipment, system and/or
area for visual check (any equipment, system and/or area specified regarding
the presence of the materials listed in appendix 1 by document analysis
should be entered in the List of equipment, system and/or area for visual
check);
- .2 List of equipment, system
and/or area for sampling check (any equipment, system and/or area which
cannot be specified regarding the presence of the materials listed in
appendix 1 by document or visual analysis should be entered in the List of
equipment, system and/or area as requiring sampling check. A sampling check
is the taking of samples to identify the presence or absence of hazardous
material contained in the equipment, systems, and/or areas, by suitable and
generally accepted methods such as laboratory analysis); and
- .3 List of equipment, system and/or
area classed as "potentially containing hazardous material" (any equipment,
system and/or area which cannot be specified regarding the presence of the
materials listed in appendix 1 by document analysis may be entered in the
List of equipment, system and/or area classed as "potentially containing
hazardous material" without the sampling check. The prerequisite for this
classification is a comprehensible justification such as the impossibility
of conducting sampling without compromising the safety of the ship and its
operational efficiency).
4.2.7.2 Visual/sampling checkpoints should
be all points where:
- .1 the presence of materials to be
considered for the Inventory part I as listed in appendix 1 is likely;
- .2 the documentation is not
specific; or
- .3 materials of uncertain
composition were used.
4.2.8
Onboard visual/sampling check (step 4)
4.2.8.1 The onboard visual/sampling check
should be carried out in accordance with the visual/sampling check plan. When a
sampling check is carried out, samples should be taken and the sample points should
be clearly marked on the ship plan and the sample results should be referenced.
Materials of the same kind may be sampled in a representative manner. Such materials
are to be checked to ensure that they are of the same kind. The sampling check
should be carried out drawing upon expert assistance.
4.2.8.2 Any uncertainty regarding the
presence of hazardous materials should be clarified by a visual/sampling check.
Checkpoints should be documented in the ship's plan and may be supported by
photographs.
4.2.8.3 If the equipment, system and/or area
of the ship are not accessible for a visual check or sampling check, they should be
classified as "potentially containing hazardous material". The prerequisite for such
classification should be the same prerequisite as in section 4.2.7. Any equipment,
system and/or area classed as "potentially containing Hazardous Material" may be
investigated or subjected to a sampling check at the request of the shipowner during
a later survey (e.g. during repair, refit or conversion).
4.2.9
Preparation of part I of the Inventory and related documentation (step 5)
If any equipment, system and/or area is classed as either "containing
hazardous material" or "potentially containing hazardous material", their
approximate quantity and location should be listed in part I of the Inventory. These
two categories should be indicated separately in the "Remarks" column of the
Inventory
4.2.10 Testing methods
4.2.10.1 Samples may be tested by a variety
of methods. "Indicative" or "field tests" may be used when:
- .1 the likelihood of a hazard is
high;
- .2 the test is expected to
indicate that the hazard exists; and
- .3 the sample is being tested by
"specific testing" to show that the hazard is present.
4.2.10.2 Indicative or field tests are
quick, inexpensive and useful on board the ship or on site, but they cannot be
accurately reproduced or repeated, and cannot identify the hazard specifically, and
therefore cannot be relied upon except as "indicators".
4.2.10.3 In all other cases, and in order
to avoid dispute, "specific testing" should be used. Specific tests are repeatable,
reliable and can demonstrate definitively whether a hazard exists or not. They will
also provide a known type of the hazard. The methods indicated are found qualitative
and quantitative appropriate and only testing methods to the same effect can be
used. Specific tests are to be carried out by a suitably accredited laboratory,
working to international standardsfootnote or equivalent, which will provide a written report
that can be relied upon by all parties.
4.2.10.4 Specific test methods for appendix
1 materials are provided in appendix 9.
4.2.11
Diagram of the location of hazardous materials on board a ship
Preparation of a diagram showing the location of the materials listed in
table A is recommended in order to help ship recycling facilities gain a visual
understanding of the Inventory.
4.3 Maintaining and updating part I of
the Inventory during operations
4.3.1 Part I of the Inventory should be
appropriately maintained and updated, especially after any repair or conversion or
sale of a ship.
4.3.2
Updating of part I of the Inventory in the event of new
installation
If any machinery or equipment is added to, removed or replaced or the
hull coating is renewed, part I of the Inventory should be updated according to the
requirements for new ships as stipulated in paragraphs 4.1.2 to 4.1.4. Updating is
not required if identical parts or coatings are installed or applied.
4.3.3
Continuity of part I of the Inventory
Part I of the Inventory should belong to the ship and the continuity and
conformity of the information it contains should be confirmed, especially if the
flag, owner or operator of the ship changes.
4.4 Development of part II of the
Inventory (operationally generated waste)
4.4.1 Once the decision to recycle a ship
has been taken, part II of the Inventory should be developed before the final
survey, taking into account that a ship destined to be recycled shall conduct
operations in the period prior to entering the Ship Recycling Facility in a manner
that minimizes the amount of cargo residues, fuel oil and wastes remaining on board
(regulation 8.2 of the Convention).
4.4.2
Operationally generated wastes to be listed in the Inventory
If the wastes listed in part II of the Inventory provided in table C
(Potentially hazardous items) of appendix 1 are intended for delivery with the ship
to a ship recycling facility, the quantity of the operationally generated wastes
should be estimated and their approximate quantities and locations should be listed
in part II of the Inventory.
4.5 Development of part III of the
Inventory (stores)
4.5.1 Once the decision to recycle has been
taken, part III of the Inventory should be developed before the final survey, taking
into account the fact that a ship destined to be recycled shall minimize the wastes
remaining on board (regulation 8.2 of the Convention). Each item listed in part III
should correspond to the ship's operations during its last voyage.
4.5.2
Stores to be listed in the Inventory
If the stores to be listed in part III of the Inventory provided in
table C of appendix 1 are to be delivered with the ship to a ship recycling
facility, the unit (e.g. capacity of cans and cylinders), quantity and location of
the stores should be listed in part III of the Inventory.
4.5.3
Liquids and gases sealed in ship's machinery and equipment to be listed in
the Inventory
If any liquids and gases listed in table C of appendix 1 are integral in
machinery and equipment on board a ship, their approximate quantity and location
should be listed in part III of the Inventory. However, small amounts of lubricating
oil, anti-seize compounds and grease which are applied to or injected into machinery
and equipment to maintain normal performance do not fall within the scope of this
provision. For subsequent completion of part III of the Inventory during the
recycling preparation processes, the quantity of liquids and gases listed in table C
of appendix 1 required for normal operation, including the related pipe system
volumes, should be prepared and documented at the design and construction stage.
This information belongs to the ship, and continuity of this information should be
maintained if the flag, owner or operator of the ship changes.
4.5.4
Regular consumable goods to be listed in the Inventory
Regular consumable goods, as provided in table D of appendix 1 should
not be listed in part I or part II but should be listed in part III of the Inventory
if they are to be delivered with the ship to a Ship Recycling Facility. A general
description including the name of item (e.g. TV set), manufacturer, quantity and
location should be entered in part III of the Inventory. The check on materials
provided for in paragraphs 4.1.2 and 4.1.3 of these guidelines does not apply to
regular consumable goods.
4.6 Description of location of hazardous
materials on board
The locations of hazardous materials on board should be described and
identified using the name of location (e.g. second floor of engine-room, bridge DK,
APT, No.1 cargo tank, frame number) given in the plans (e.g. general arrangement,
fire and safety plan, machinery arrangement or tank arrangement)
4.7 Description of approximate quantity
of hazardous materials
In order to identify the approximate quantity of hazardous materials,
the standard unit used for hazardous materials should be kg, unless other units
(e.g. m3 for materials of liquid or gases, m2 for materials
used in floors or walls) are considered more appropriate. An approximate quantity
should be rounded up to at least two significant figures.
