Whiteboard Discussion: Scalable Accuracy - What Level of Detail is Necessary in Your Risk-Based Inspection Assessment?

Video Description 

In this latest Whiteboard Discussion, Inspectioneering Chief Editor Greg Alvarado takes a few minutes to discuss the concept of "Scalable Accuracy," a term used to describe the varying levels of detail necessary to consider when planning and conducting a Risk-Based Inspection (RBI) assessment.  So how accurate does your RBI assessment need to be?  To what level of detail should the damage mechanisms review and RBI be performed? Some units operating in "clean" environments that have virtually no internal corrosion may have some external corrosion or damage mechanisms that need consideration and vice versa. Does your RBI program facilitate scalable accuracy? In other words, are you able to manage your equipment, via your work processes, to the level of detail needed for an "apples to apples" relative risk comparison? Is your RBI approach flexible and credible enough to handle the gamut of fixed equipment risks encountered on a daily basis?

The presenter briefly addresses these questions in terms of relative risk and discusses how your risk assessment should include the level of detail appropriate for the equipment or unit under review, and the circumstances under which it operates.
