3.1 Where the Code requires that a particular
fitting, material, appliance or apparatus, or type thereof, piece
of equipment or machinery shall be fitted or carried in a vessel,
or that any particular provision shall be made, the Administration
may permit any other fitting, material, appliance or apparatus or
type thereof, piece of equipment or machinery to be fitted or carried
or other provision to be made in that vessel where it is satisfied
by trials or otherwise that the alternative is at least as effective
as that required by the Code.
3.2 The Administration may exempt any vessel or
description of vessels from all or any of the provisions of the Code,
as shall be specified in the exemption, provided that the Administration
is satisfied that compliance with such provision is either impracticable
or unreasonable in the case of that vessel or description of vessels.
The exemption may be issued on such terms, if any, as the Administration
may specify and subject to giving reasonable notice, alter or cancel
any such exemption.
