5 Levels of Risk Analysis. How many do you have?
Equipment risk analysis is a core activity in plant risk management. Many spears were broken about prioritizing individual equipment monitoring and risk controls, to ensure its safe and reliable operation. We have arrived to the capability of performing risk assessments at 5 levels of depth. This multi-level approach enables a two-fold cost/benefit optimization: analysis cost is minimized and a risk cost analysis is enabled where required. This article shows applications to pressure equipment inspection planning (RBI). Drivers for multi-level RBI We naturally recognize two levels of approach to engineering problems: First-pass system screening for criticalityIn-depth analysis of critical elements only This sequence of tasks well optimizes time and efforts. The only precaution is not to get locked into the screening step (1) solely. Critical objects require a detailed analysis (2)…
