FEATURES
The LOPA Module provides intuitive worksheets to standardize the LOPA process and conduct IPL Assessments. The Dynamic Risk Matrix is configurable and offers real-time risk monitoring and identification. Instant reports and KPIs reveal unmitigated risks to allow IPL gap closure scheduling and progress. These reports offer unprecedented review of risk mitigation strategies.
- Facilitate LOPA studies directly in SLM or import LOPA data from other sources
- Configure LOPA data library tables to company standards and procedures
- Create LOPAs from previously saved LOPA templates
- Link LOPA scenarios with recorded HAZOP module scenarios
- Use same list of barriers as HAZOP module for LOPA scenario mitigation
- Automatically calculate barrier target requirements as LOPA scenarios are documented
- Automatically calculate expected demand rates on barriers
- Combine barrier target requirements across multiple scenarios using the same barrier
- View barrier diagrams displaying sequence of threat propagation through barriers
- Schedule and track scenario and barrier gap closure
- Plot LOPA scenarios on SLM’s Dynamic Risk Matrix showing effect of invalid/inadequate barriers, with option to toggle results to include effects of barriers currently in bypass status
- Link IPL barriers with actual protective systems designed to meet barrier target requirements
- Automatically generate barrier registers from LOPA data
- Track LOPA and barrier recommendations
- Generate Action Items from LOPA recommendations that are automatically added to the Action Item Tracker to ensure all recommendations are mitigated and addressed in a timely manner.
- Generate Critical Equipment List to provide a list of “equipment at risk” identified during a LOPA Study along with the highest risk in each of the equipment's associated LOPA Sheets.
- Filter reports of LOPA scenarios to find specific scenarios containing specific barriers, types of barriers, equipment, and level of severities
- Generate LOPA Recommendations Report to review all recommendations documented within a LOPA Study
