Dear list:
I am interested in finding out how other companies handle the determination of safety interlocks that go into the safety interlock system (aka ESD, SIS, etc.). I am not interested in quantitative analysis, but instead would like
to find out how qualitative analysis can be incorporated into PHA's or HAZOP's. If consequence and probability rankings are used, I am interested in how they are defined and how the results are used to determine SIS requirements. I have read many papers and books on this subject, but I would like to know more about how users are actually doing this in practice.
Also, if anyone is using qualitative analysis to determine SIL, I am interested in problems associated with this method. Does it work well?
Any information about this subject is greatly appreciated.
