Sonomatic has pioneered the formal industry approach for NII and are leaders in the implementation of the developed NII approaches. Our clients include many of the major international operators and our involvement at the assessment, planning, inspection and evaluation stages, covers over 1100 major process vessels worldwide. Sonomatic‘s ability to offer the full range of NII campaign services ensures that clients get the maximum benefit while retaining full confidence in equipment integrity.
For pressure vessels, Non-Intrusive Inspection (NII) is increasingly being utilized as an alternative approach to the traditional Internal Visual Inspection (IVI), with some organisations aiming to eliminate vessel entry by 2026.

NII Offers Several Benefits, Including:
Fully Integrated NII Service
As key authors of the NII recommended practice HOIS-RP-103, Sonomatic are global leaders in the implementation of NII. As such, we are uniquely positioned to deliver fully integrated NII services including comprehensive inspection planning, assessments and evaluation services in addition to advanced NDT capabilities. Our Specialised Integrity Services group has a strong track record of successfully delivering pressure vessel NII for large scale offshore and onshore projects.
Assessment and Work Scope
Each vessel is individually considered to determine whether NII is appropriate and, where applicable, a work scope will then be developed. As part of the work scope, a 3D model of the vessel will be created using Sonomatic’s SIMS software. It is important to note that the below assessment is not a push button approach. While the recommended practice does stipulate a process to follow, experienced technical input and understanding is required.
- Auditable Trail (Impartiality Guarantee)
- Expert Review of Work Scopes
- Live Geolocated 3D Corrosion Maps Produced at Collection.
- Substitute/Additional Areas or Techniques as Needed
