Design Comparison Using Risk Based Inspection (RBI)

When designing a new plant, it is important to consider the costs associated with the day-to-day operations of each unit, and not just initial purchase cost (i.e., the cost of the asset). The low initial cost of a unit might be offset by a high maintenance cost or an even higher expected risk cost (i.e., additional costs associated with the chance of failure). When multiple designs are available as possible choices, the comparison of the designs must consider all costs based on each design's predicted performance throughout the life cycle in order to determine the best design for the particular environment. The example given in this article, based on the analysis provided in API RP 581, showcases the ability to compare designs of heat exchanger tube bundles using ReliaSoft's RBI software. A similar methodology can also be used for other pressurized components.

Calling for Presentation Proposals!

The Applied Reliability Symposium comes to Europe only once a year — don't miss your opportunity to be a presenter in Amsterdam, Netherlands in April 2015! The ARS Europe proposal deadline is October 30, 2014. Presentation topics should be based on practical reliability and quality engineering practices derived from real-life experience. The primary author for each presentation delivered at the Symposium will receive complimentary registration to the event and the opportunity to win one of the Excellent Presentation Awards. For additional information and to download the submission form, please visit the ARS Europe website at http://www.ARSymposium.org/europe/index.htm.
