Integrity Management
The program that ranks pipeline threats by risk and decides where to inspect, dig and repair, shown here as an integrity dig.
What it does
Combines in line inspection, cathodic protection data, patrol reports and history to find the highest risk spots first, then confirms and repairs them in the field. In Canada, the Onshore Pipeline Regulations require an integrity management program and adopt CSA Z662.
