Integrity Risk Indicators (IRIs)
Maximizing petroleum profitability requires continuous optimization of operating conditions - such as adjusting a distillation column’s temperature profile to process heavier, more acidic crude blends. However, even minor operational changes can rapidly shift a system into an elevated corrosion regime, potentially accelerating asset degradation, reducing equipment reliability, and exposing facilities to unplanned outages. Hence, the economic value of process optimization is inseparable from the ability to understand and manage its associated integrity risks. This chapter presents Integrity Risk Indicators (IRIs), which utilize a fast, Bayesian RBI-style simulation engine to enable rapid screening and sensitivity analyses within minutes - allowing process and integrity teams to evaluate operational scenarios before implementation. These indicators therefore serve as a tool that bridges the gap between daily risk awareness and the formal, consequence-based modelling required for full RBI studies.
