Risk Based Inspection (RBI) & Assessment

Nov 6

Risk Based Inspection (RBI)

Although Viking is familiar with the API approach to RBI, we have developed a streamlined in‐house methodology that enables RBI programs to be developed in a much shorter timeframe with a documentation process that is fully auditable and traceable in the same way as the API approach. Viking can help you design and implement a tailor-made Risk Based Inspection (RBI) Program.

A well-designed RBI program provides more than just optimized inspection scheduling – it can lead the way to effective corrosion management and cost savings. Assessments made during RBI workshops can inform operational activities and improve system performance and equipment longevity.

Barriers to integrity threats are either “design-out” or “operational”. A design-out barrier is intrinsic to the system and can usually fully mitigate the threat. An operational barrier is a variable condition that needs to be actively managed to work, i.e. to mitigate risk. Some degradation mechanisms may have no barrier at all, in which case risk management relies entirely on inspection and replacement.

An RBI program that facilitates proper monitoring of conditions and reliable management of operational barriers can boost your bottom line.

Viking’s RBI Services can be tailored to provide a wide range of services, including:

Damage Assessment and Corrosion Modeling
Corrosion Loop / Circuits Identification
CML (Condition Monitoring Location) Placement and Use
Fitness for Service Assessment / Life Extension
Root Cause Analysis (RCA)
Determination of Inspection Intervals and Schedules
Corrosion Management Manual Development and Implementation
Risk Assessment Matrix (RAM) Development for Equipment Reliability
Probability of Failure (POF) and Consequence of Failure (COF) Characterization
ALARP Risk Reduction Strategies

Together, we’ll inspect your facility for maximum value.

HAZOPs are not as effective as they should be. Duhon and Sutton (2010, SPE 120735) identified many reasons why we don’t learn as much as we should from HAZOPs.
