The simple answer to the question of whether SIS devices need to be certified is, "No," but operators and the industry as a whole continue to ask for certification anyway. Why is this?, 01 Aug 2015 00:00:00 GMTNew Developments, 01 Aug 2015 00:00:00 GMTTen sure steps to substandard reliability performanceEquipment reliability can be enhanced or jeopardized by many different actions, inactions, commissions and omissions. Reliability may be a hollow term to many. Still, first and foremost, a reliable plant is a safe plant., 01 Aug 2015 00:00:00 GMTWetted surface area calculations for fire-relief sizing in ASME pressure vesselsAlthough individual operating facilities take many steps to protect plants from fire, pressure vessels within a fire zone must be protected by a pressure safety valve (PSV). Proper calculation of the vessel’s wetted surface area is a crucial step in properly sizing a PSV., 01 Aug 2015 00:00:00 GMTHP InnovationsWhat's new in HPI innovations, 01 Jul 2015 00:00:00 GMTSafety lifecycle management challenges in hydrocarbon processing plantsMany automation and SIS vendors to the downstream HPI do not provide safety lifecycle management software that extends beyond initial commissioning work. In many cases, only the bare minimum SIF proof testing has been performed for the most critical protective and mitigative functions., 01 Jul 2015 00:00:00 GMTTrends from the 2015 AFPM Maintenance and Reliability ConferenceOver the decades, there have been good and not-so-good trends presented at this event, and the 2015 maintenance and reliability conference was no exception., 01 Jul 2015 00:00:00 GMT
