Integrity Operating Windows (IOWs) are limits and ranges placed on key process variables to make sure equipment integrity and safe operations are maintained.

Keeping your facility’s complex processing equipment fully operational directly affects your bottom line. While predictive damage modeling is part of a robust asset integrity program, variable process or operating conditions (e.g. alternative containment levels, temperatures, pressures, etc.) have the potential to introduce new damage mechanisms or to accelerate damage mechanisms already predicted in the study.

While operations need to be flexible to operate the unit to meet production’s needs, operating outside of the inspection department’s assumptions or prescriptions can accelerate the degradation of an asset and lead to unplanned loss of containment scenarios. Consequently, your facility may suffer from downtime and loss of production, which negatively affects funds and profitably. However, by maintaining your assets within prescribed operating conditions, you could reduce the risk of early failure. This can be accomplished through Integrity Operating Windows (IOWs).

Pinnacle can help your facility proactively identify ranges and limits for key process variables in each unit by providing valuable operating guidance and parameters in which assets can optimally perform. By identifying potential damage mechanisms and critical integrity process variables across a unit, Pinnacle determines acceptable upper and lower operating thresholds. These operating parameters are prioritized by criticality level (information, standard, or critical). Pinnacle provides action recommendations with associated response times, ensuring that proper communication channels exist should those IOWs be breached.
