Non-Intrusive Inspection (NII)

Using Non-Intrusive Inspection (NII) to complement Risk Based Inspection (RBI) can decrease shut down times, reduce inspection costs and improve integrity outcomes for pressure equipment.
 
Taking pressure vessels offline, purging and entering them for visual inspection means high costs and potential safety implications for inspectors.
 
Non-Intrusive Inspection, using emerging non-destructive testing (NDT) techniques, allows some vessels to be inspected in service and produces quantitative data that can be accurately trended. 
 
Our expertise
 
For existing pressure vessels, SVT can perform applicability screening to determine whether they are suitable for Non-Intrusive Inspection techniques. If suitable, SVT can prepare inspection work packs for NDT personnel to follow.
 
SVT can also design pressure vessels to ensure they are suitable for NII.
