Difficulties with Fire and Gas
•
How to apply the risk based approach post event?
–
LOPA, Risk Graph, even quantified approaches do not help
–
UK HSE Hydrocarbon release database:
–
“60% of HC releases detected in open modules”
–
F&G Detector placement >> detector integrity (SIL bla)
•
One to many relationship …
–
Achieving even SIL 1 near impossible
–
But just how many final elements actually need to operate?
–
We can’t know, but it’s not all of them …
–
Depends where the event (e.g. leak) occurs
