Integrity Operating Windows

Establishment of integrity operating windows that define the process parameter boundaries within which equipment damage mechanisms remain within expected limits, supporting proactive integrity management between inspections.

Integrity operating windows define the critical process parameters — such as temperature, pressure, pH, flow velocity, and chemical concentration — that must be maintained within specified limits to keep equipment damage rates within the assumptions used in RBI and inspection planning. TES Canada establishes IOW programmes that connect process operations directly to equipment integrity outcomes.

TES Canada works with operations, process engineering, and integrity teams to identify the parameters most relevant to each damage mechanism, define standard, alert, and critical operating limits, and establish monitoring and response protocols. IOW programmes provide an early-warning mechanism that allows operators to take corrective action before process excursions accelerate damage beyond the rates assumed in the current inspection plan.

Effective IOW implementation bridges the gap between periodic inspection events by providing continuous or near-continuous integrity assurance through process data monitoring. TES Canada delivers IOW programmes that are practical for field implementation, integrated with existing control systems where possible, and aligned with the facility's overall integrity management framework.
