This session will explore the application of Quantitative Risk Assessment (QRA) methodologies to subsea well interventions, highlighting their role in decision-making, regulatory compliance, and operational safety. Discussions will cover how QRA can be used to evaluate well integrity risks, compare alternative intervention strategies, and prioritise resources in complex offshore environments. Case studies will highlight practical applications.
