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 run...

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 ...

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 branner med opphav i prosessområdet. Ra...

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...

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 ...
