Denne forstudierapporten sammenstiller informasjon om status og utfordringer med hensyn til tilstand og vedlikehold av sikkerhetskritisk utstyr i petroleumsvirksomheten. Dette dekker grensesnittet mellom vedlikeholdsstyring og barrierestyring. Sammenstillingen baserer seg på en gjennomgang av r...

Reliable failure rate estimates of safety critical equipment is crucial for verifying performance requirements and for trending the safety performance of the equipment. Joint industry efforts, like OREDA, Exida and PDS handbooks, supported by international standardization on data collection such as ...

Det er i denne rapporten gjort en kartlegging og vurdering avhvordan petroleumsnæringen definerer og anvender begrepet "Worst Credible Process Fire" (WCPF). Begrepet brukes ved utforming av innretninger for å sikre at disse er robuste når det gjelder å motstå brann...

The Petroleum Safety Authority Norway has stressed the need to manage and monitor operational and organizational barrier elements. Personnel should understand what barriers have been established and which function they are intended to fulfil, and performance requirements should be defined in respect...

In the petroleum industry, there has been an increasing focus on barrier management to prevent major acci-dents, such as the Macondo well blowout in 2010. Awareness about the status of the safety barriers is one important aspect of risk management. For this purpose the use of a barrier status panel ...

Collection and monitoring of specific indicators may enable dynamic and proactive risk assessment. In fact, such collection, improved by today's advanced information technology systems, may provide real-time information on the overall risk variation. Moreover, monitoring human and organizational fac...

Safety instrumented systems often employ redundancy to enhance reliability, but the intended effect may be reduced when common cause failures are taken into account. It is often assumed that a certain fraction of component failures will occur close in time, due to a shared cause. Unfortunately, few ...
