Introduction
Asset integrity management (AIM) is more important than ever, especially under the current market-driven trend of prolonged operation. This necessitates a notable effort for risk reduction as part of operational excellence and to comply with stringent safety regulations. Risk Based Inspection (RBI) is a key AIM tool by which risk is minimized and costs are optimized. Usually, implementation of an RBI is done through a software that models variables and solves complex equations. Such software may be a legacy system which the owner-user developed, or it could be one of the many available options on the market today.
Software implementation, including RBI, comes with a lot of ad-hoc challenges and pitfalls as suggested by Flory [2] and Webb [3]. There are numerous options for RBI software currently available, and they may differ by design, purpose, function, scope and capabilities. Maguire [4] recognizes the difficulty in deciding which software to opt for. This article highlights several key integrity-related aspects to consider when selecting RBI software.
