Corrosion under Insulation (CUI) and monitoring of degradation under Engineered Temporary Wraps has proven to be a challenge to reliably detect and monitor using NDT methods.
Pulsed eddy-current has been identified as a potential NDT method for this application.
This project evaluates the effectiveness of the currently available equipment to detect and assess the anticipated degradation under in-service conditions.
The components tested and the degradation are representative of those to be found in-service.
The outcome of the project is aimed at defining the limitation of the method relative to:
 Typical Component(s)
 Representative degradation
 The dimensions of the degradation
