Periodic Reliability Assessments used for barrier performance monitoring

Periodic Reliability Assessments (PRA) are performed during the operational phase of an installation to examine whether equipment and barriers meet their preset performance requirements based on their actual performance and historical failure data.

By utilization of PRAs, ORS is able to monitor and assess performance of equipment across various installations, benchmark equipment performance against recognized data sources, ensure compliance with regulatory requirements, identify and avoid systematic errors, justify and optimize preventive maintenance intervals.


ORS offers PRAs for all types of safety barriers and safety critical equipment. In order to provide high quality and to the point service our risk management experts work in close cooperation with the client throughout the assessment.
