Oceaneering International - Stress Concentration Tomography

Project summary

The OGTC is collaborating with Oceaneering and Spier Hunter to develop a new inspection technique for Corrosion Under Insulation. The project aims to adapt existing Stress Concentration Tomography (SCT™) currently used to inspect buried pipelines, to develop a tool capable of rapidly screening insulated pipework with high probability of detecting corrosion defects. It has the potential to lower maintenance costs by up to 60% and reduce the number of hydrocarbon leaks - saving the UKCS up to £130million per annum.

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 has the potential to help unlock these cost savings.
