The scope of this program is to advance risk management and analyses critical failure rates and quantify system safety based on OLF Guideline, and subdivided into dangerous failures and spurious trip failures which is either detected or undetected.
High quality reliability data on subsea components is needed to perform reliability analyses. The existing OLF Guideline.
Safety systems are items of great influence on a plant’s safety and integrity, and failure on these systems are therefore dealt with in a more dedicated way than other equipment. This equipment are typical used for fire detection/extinguishing, emergency shutdown and process shutdown if an unsafe situation arrives. As these systems frequently are used as being in normal use, and expected to function when called upon, it becomes utmost important to know the reliability of this equipment, notably the probability that the equipment will work when called upon.
To establish recommended reliability data for a selection of oil and gas control system components (Off and On shore) based on OLF Guideline.
The recommended reliability data consists of critical failure rates. According to standard taxonomy, critical failures are subdivided into dangerous failures and spurious trip failures which is either detected or undetected.
Failure rates are the basis to quantify system safety when combined with system configuration, common cause failures (failures that cause redundant pairs to fail simultaneously) and testing intervals
- Analyse of collected reliability data based on OLF Guideline.
- Systematize available intervention data for critical equipment components
- Review of recent years of critical equipment failures
- Systematize this information, and interact with operating unit to assess the failures.
- Establishment of general equipment history for various facilities, systems and equipment for monitoring the operational phase and basis for technology improvements in the design phase
