Systematic Safety Integrity; what you need to know.

By |2018-07-06T12:24:59+00:00July 6th, 2018|Kevin Mitchell, News, Safety Instrumented System, Services, Vertigo|

There's a lot of confusion about Systematic Safety Integrity in new IEC61511.  We are starting to see devices certified for SIS applications to have a rated Systematic Capability (SC) of 2.  What does this mean?  Is this yet another hurdle I need to jump over to meet a SIL target?  Let's shine some light on Systematic [...]

When all your eggs are in the BPCS and SIS protection layers

By |2018-01-26T12:22:25+00:00January 26th, 2018|Arbor, Kevin Mitchell, News, Safety Instrumented System, Vertigo|

During Layer of Protection Analysis (LOPA) of high hazard scenarios, we often rely on a diversity of protections including instrumented and non-instrumented safeguards.  Invariably, we run into situations where instrumented safeguards must bear the full weight of risk reduction.  Of course, we never want to design a Safety Instrumented Function to a SIL 4 or [...]

How do I decide on the need for toxic gas detection?

By |2018-01-26T11:43:48+00:00August 10th, 2017|Effigy, Fire and Gas Systems, Kevin Mitchell, Safety Instrumented System|

We were recently asked about placing Hydrogen Sulfide (H2S) gas detectors in an area of the process where no H2S gas is normally present. Does the possibility for process upset conditions to abnormally result in the presence of toxic gas give rise to a requirement for detection? There was no way to simply answer the [...]

Reducing Turnaround Time and Cost

By |2018-01-26T11:44:12+00:00July 26th, 2017|Jim McGlone, Process Hazards Analysis, Reducing Turnaround Cost, Safety Instrumented System, Vertigo|

In todays oil and chemicals market, time and budgets are strained to remain operational with a slight profit. Many facilities are making difficult operational and turnaround decisions to survive while possibly putting their operation at risk at the same time. There might be a significant way to reduce time and cost during operations and [...]
