Non-Intrusive Inspection (NII)

NII is a approach commonly used in mainland UK process industries where it has provided significant financial benefits without compromising safety.

NII allows pressure vessels to be inspected with the equipment online and avoids entry into confined spaces to perform the investigation.

NII helps shorten turnarounds (TARs) by reducing the amount of intrusive work during the event allowing it, where possible, to be completed at other times when the asset is online. 

Minimising plant downtime is a business imperative in the process industries. The inspection of equipment, to maintain safe operation and fulfil statutory requirements, is a major driver of the frequency and duration of planned outages. Reducing plant downtime has a significant benefit to the bottom line.
