— OIL AND GAS CASE STUDY - MAJOR OIL & GAS OPERATOR, UK Long Range Ultrasonic Testing (LRUT) inspections Inspection of the natural gas underground pipework at an onshore gas terminal was required to confirm the integrity of the system. Typically this would require full excavation, which in this instance would amount to approx. 34m including under site roads. As a result alternative inspection techniques were considered through the ABB Risk Based Inspection (RBI) process. This ultimately led to the selection of LRUT, this long range Non-Destructive Testing (NDT) technique, utilises ultra-sonic sound waves to detect wall loss along a length of pipework. This allowed for only sections of the pipework requiring excavation. LRUT inspection technique LRUT is an ultra-sonic tech
