ESR Technology Ltd - Evaluation of CUI Inspection Technologies

Project summary

This HOIS JIP is focused on independent evaluation trials in the challenging areas of inspection of external corrosion and Corrosion Under Insulation (CUI). This 3 year project will provide enhanced facilities for the ongoing evaluation of advanced non-destructive testing (NDT) equipment, to manage CUI. With 8 trials planned including Microwaves (on non-conducting lagging), Pulsed-Eddy Current (Eddyfi Lyft, Maxwell NDT), other advanced Electro Magnetic techniques (e.g. Russell NDE Bracelet Probe, Jentek) and Radiography (real-time and DDA). The outcomes of the trials shape and provide input into the final deliverable of this project i.e. HOIS guidance document for CUI inspection and external corrosion scabs.

Potential Industry Value

Corrosion Under Insulation (CUI) poses a significant operational, safety and economic challenge. Since 1984, out of the 137 major oil and gas accidents reported within the EU over 20% have been associated with CUI. It is currently estimated that CUI incurs 40 - 60% of the process plant maintenance costs within the UK Continental Shelf (UKCS) and the value impact to the industry for better inspection techniques would be in the region of £130M per annum to the UKCS. This project will be instrumental in raising awareness of available technology and has the potential to help unlock the cost savings.
