Non-Intrusive Inspections (NII) offers operators the opportunity to maintain production of pressure systems and reduce shutdown durations by applying the NII process.
NII can be applied after evaluation for NII suitability on selected pressure vessels. The NII process should equal or exceed the data collection of Internal Visual Inspections (IVI).
The benefits of NII are:
NII can be conducted intermittently between IVI and be carried out prior to shutdown to allow for a targeted repair strategy if its required.
Safer execution of workscope compared to IVI, no breaking containment, cleaning, no man entry to confined spaces
No downtime, maintain production.
Specific technique selection for expected degradation mechanisms
