HOUSTON, TEXAS (Ofelia Paredes, Energy Analytics Institute, 24.Apr.2025) — DNV successfully completed the technology qualification (TQ) of Subtera‘s passive terahertz sensor technology designed to detect corrosion under insulation (CUI) and the trapped moisture that causes it — a pervasive challenge in industrial plants.
CUI is a leading cause of asset failure in industries such as oil and gas and chemicals, which has contributed to more than 20% of major oil and gas accidents in the EU in the past 35 years, posing significant safety, environmental, and financial risks, DNV said on 24 Apr. 2025 in an official statement.
Developed over a decade by Subtera, an ISO9001 certified organization that provides non-intrusive CUI and moisture detection solutions based at the Rutherford Appleton Laboratory in the UK, its technology enables real-time, non-intrusive visibility of pipe surfaces — without the need to remove insulation or disrupt operations.
Subtera’s Pi360, is a handheld, cloud-connected CUI detection camera that allows asset integrity teams to efficiently screen operational pipework protected by non-metallic cladding. It detects corrosion, identifies moisture ingress, and assesses fabric layers — all while wirelessly transmitting data for analysis and reporting.
