5.3.1 In those cases where it may not be possible
to define the evaluation criteria during the Preliminary Design phase,
the Submitter and Administration should agree on the strategy for
defining such criteria.
5.3.2 If the evaluation criteria cannot be fulfilled
the approval process should be either terminated or restarted with
a modified design.
5.3.3 Submitter and Administration should consider
the impact that one particular evaluation criterion might have on
other areas that might not be specifically part of the alternative
design. For example, the failure of a particular safeguard may not
only affect the life safety of passengers and crew in the adjacent
space, but it may result in the failure of some system affecting the
overall safety of the ship.
5.3.4 The Revised Guidelines for Formal
Safety Assessment (FSA) for use in the IMO rule-making process (MSC-MEPC.2/Circ.12)
contains information on risk acceptance evaluation criteria.
