What you receive

Evidence you can act on. A record that grows.

  • A complete engineering assessment of each asset, above and below the water
  • A structured report: condition grade, measurements, acoustic evidence, prioritised recommendations
  • Every result stored on the PRAFIRA platform against the asset, compared at the next visit
  • An inspection plate on the asset, and your own login to the record

What your site needs to do

Keep the asset running. We do the rest.

  • Nothing drained, nothing isolated, no confined-space entry
  • Site induction, a site contact and safe access to the asset
  • A purchase order against your emailed quotation
  • About one day on site for every three assets, with your operations unaffected

What we inspect

Any submerged asset in a treatment works. In service.

You know what is in your assets. We see its condition without taking them out of service.

Every component identified, imaged, measured and graded.

Each component is given an identity, imaged, measured where geometry permits and graded good, monitor or act. An engineer interprets every capture. You receive condition, not raw sonar.

The PRAFIRA application

Every asset, its condition, its risks and what to do next. In one place.

Register, condition and risk, open defects, maintenance due, scheduled visits and repairs. Every inspection kept in the asset's history.

Representation of the PRAFIRA application · illustrative data

The technology

Three technologies. One inspection.

01

Acoustic imaging

Multibeam sonar builds the picture from sound. Submerged structure resolved in water with no visibility, watched live at the tank side.

How it works →
Sonar entering the water at the tank side with engineers watching the live image
02

Engineering survey

Above the water, nothing is estimated. Levels, geometry, alignment and wear measured against a datum so the next visit measures change.

What is recorded →
Engineer taking a level reading on a scraper bridge
03

Asset intelligence

Every capture is checked in the mobile unit before it is issued, then stored against the asset and compared at the next inspection.

The platform →
Engineers reviewing acoustic captures inside the PRAFIRA mobile unit
