6.1 When performing a detailed assessment of critical
systems, additional information may be necessary. The ship's description,
described in section 3, should be supplemented, for each identified
critical system, with the following, as applicable:
-
.1 details of pipes, cables or other devices connecting
the components of the critical system, or connecting different critical
systems including their location within the affected area;
-
.2 details of any manual action providing the
required ship systems' functionality (see also paragraph 5.2.3); and
-
.3 details of any operational solution forming
part of the design criteria.
6.2 Where acceptable to the Administration, a
quantitative analysis can be carried out as a part of the detailed
assessment of all critical systems. As an example, the following may
be performed:
-
.1 quantitative analysis of fire risk within a
space, supplemented by fire engineering analysis and/or fire testing
where necessary (e.g., to assess consequences of a fire casualty on
a system or system component);
-
.2 Failure Mode Effect Analysis (FMEA) of a system
or system component analyses in accordance with standard IEC 60812, Analysis techniques for system reliability – Procedure for
failure mode and effects analysis (FMEA) or resolution MSC.36(63), annex 4 (Procedures
for Failure Mode and Effects Analysis), would be acceptable; and
-
.3 detailed analysis of possibility of flooding
of internal watertight compartments and of consequences of flooding
on system components, given the location of the compartment and arrangement
of piping within the compartment.
