3.3.1 An additional survey, either general or
partial according to the circumstances, may be conducted at the request
of the shipowner after change, replacement or significant repair of
the structure, equipment, systems, fittings, arrangements and material,
which has an impact on the Inventory of Hazardous Materials.
3.3.2 Prior to the additional survey, a request
for the additional survey should be submitted by the shipowner to
the Administration or to a recognized organization along with the
ship data required for the International Certificate on Inventory
of Hazardous Materials as listed in paragraph 3.1.1.2 above.
3.3.3 The request for an additional survey should
be supplemented by the latest version of part I of the Inventory of
Hazardous Materials, and Material Declaration and Supplier's Declaration
of Conformity regarding any change, replacement or significant repair
of structure, equipment, systems, fittings, arrangements and material
since the last survey.
3.3.4 The survey should verify that Part I of
the Inventory of Hazardous Materials is properly maintained and updated
to reflect changes in ship structure and equipment, by checking Material
Declaration and Supplier's Declaration of Conformity, and should clarify
that the ship complies with regulations 4 and 5 of the annex to the Convention. The survey
should also verify that the Inventory of Hazardous Materials, especially
the location of Hazardous Materials, is consistent with the arrangements,
structure and equipment of the ship, through on-board visual inspection.
The survey should further verify that any decision by the owner to
delete equipment, system and/or area previously classed as "potentially
containing hazardous materials" from Part I of the Inventory of Hazardous
Materials is based on clear grounds for believing that the equipment,
system and/or area in question contain no Hazardous Materials.
3.3.5 The International Certificate on Inventory
of Hazardous Materials should be endorsed either by the Administration
or by any person or organization authorized by it after successful
completion of the additional survey, in accordance with regulation 11 of the annex to the Convention.
