Effective Field Inspection Tool To Detect And Assess Corrosion Under Insulation (CUI) For Piping Systems And Components

 

The winning solution is an integrated non-intrusive passive inspection technique (which detects active anomalies) with auxiliary testing and advanced data processing. The objective of the integration is to increase the probability of detection and for calibration purposes based on the principle of similarity. Ideally, active anomaly detection requires the inspected candidate to be in operating condition where these active anomalies are formed and increase in natural operating environment with the presence of various damage mechanism. PDT is capable for upstream and downstream assets such as piping, pipeline, pressure vessel, tank, jacket leg, conductor and caisson structure.

 

The technology has been piloted at PETRONAS Chemical Olefin Derivatives (PCOGD) on December 2019.
