SIS performance
Collecting and analysing the actual performance
to assess performance remains consistent with
assumed during design.
This performance analysis includes:
–
The demand rate on each SIF.
–
Failures and failure modes of equipment forming part of the SIS.
–
Cause and frequency of any spurious trips.
–
Etc.
User define the necessary corrective action to be
taken if the failure rates are assessed as greater
than what was assumed during design phase.
Dangerous fault alarms to be proof tested and in
change management.
