Non-Intrusive Inspection (NII)
The safe operation of high hazard pressure vessels requires regular inspection to confirm the internal condition of the item. Historically, this has been achieved through internal visual inspection (IVI) where shutdown of the vessel is required to allow entry. Non-intrusive inspection (NII) is a process which has the potential to offer equal, or improved, integrity knowledge for a vessel as an alternative to costly and hazardous IVI.
ESR Technology offers a range of NII services which align with the HOIS Recommended Practice in NII: HOIS-RP-103. These services are available to operators, integrity management companies, inspection providers, and EPC companies and include:
- Design of equipment for NII,
- Development of company specific processes and documentation,
