Advanced Safety Barrier Management with Inclusion of Human and Organizational Aspects

Recent major accidents have shown that the human element is not adequately treated in current risk assessments and during facility operations. A novel approach is described which combines barrier based risk assessment (the bow tie risk model) with a nuclear industry approach “Success Pathways” which provides more thorough treatment of human factors and organizational objectives. In operations, barriers are often degraded, and a system driving to near-real time barrier status has been developed which combines inspection, maintenance, audit and incident investigation methods. The Integrated Operations idea from Offshore Norway allows additional robustness to decision making.
