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 ...

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 ...

This paper describes the environmental risk acceptance criteria (ERAC) currently in use in the Norwegian offshore petroleum industry, points out their shortcomings and suggests possible alternative ways of setting such criteria. An important question is how ERAC can be formulated and applied to allo...

Many of the undiscovered oil and gas fields are found in vulnerable areas and in deep waters. The recent Deepwater Horizon accident in the Gulf of Mexico in April 2010, has clearly demonstrated that drilling operations in such areas are demanding. The society and the authorities are therefore concer...

This report summarizes the result from PDS-BIP activity 1. Focus is on non-planned acute releases to sea and the barriers applied during drilling, workover and subsea production in order to prevent such releases. The report discusses requirements to such barriers on two different levels: (1) on a hi...
