Actual SQRA Case Studies from Real Projects

​Semi-Quantitative Risk Analysis (SQRA) focuses on traditional ongoing dam safety activities in a risk-informed manner. While the failure mode analysis is the process for identifying potential failure modes, SQRA is a process to evaluate failure mode significance from a risk perspective. The SQRA approach is a risk categorization system that assigns likelihood and consequence categories to potential failure modes based on existing data and available consequence estimates. It provides a relevant risk categorization system that can help prioritize dam safety activities. This panel provides case studies using the recently published FERC Chapter 18 guidance.
 
Who should attend: Hydropower engineers, planners and managers. Anyone preparing to implement a SQRA for regulatory or planning purposes.

Why you should attend: The SQRA will be a requirement in the coming years for most FERC-licensed hydropower facilities. When done correctly, it can be a helpful tool for prioritizing dam safety activities. This panel will share their experiences and lessons learned from real case studies.
