Technical programme

 

ESR Technology is responsible for the management of all projects. The technical programme utilises two excellent HOIS facilities:

  • “NICE” facility for ex-service specimen storage and trials. This is a large collection of mainly naturally corroded ex-service specimens for blind inspection trials. The facility also contains specially commissioned manufactured specimens with various simulated defects for use in experimental programmes and trials.
  • Two ex-service pressure vessels with significant internal degradation have been donated to HOIS and these are now located on an ESR Facility where they may be used for inspection trials.

Current HOIS projects include:

    • Recommended practice (RP) and guidance documents:
          • Updates to HOIS RP and new EN standard (EN ISO 16407) for in-service digital and film radiography of pipes.
          • RP for precision ultrasonic wall thickness measurements for corrosion monitoring between repeat inspections.
          • Guidance for in-service inspection of caissons.
          • Guidance for the on-site digital radiography of new welds.

    • Trials and technique evaluation:
          • In-service inspection of pipe supports.
          • External corrosion inspection.
          • CUI inspection.
          • IVI and NII trials on two ex-service pressure vessels.
          • Non-intrusive inspection of internally CRA clad vessels.
          • Subsea inspection trials.
          • Buried piping – road crossings and dykes inspection.
    • Online information
        • Maintenance of the HOIS internet accessible Interactive Knowledge Base (IKB) which contains a wealth of information on NDT techniques, suppliers.  Members have free access.
          • Development of a new IKB for subsea inspection.

Recently completed notable projects include:

  • RP for weld corrosion inspection.
  • RP for flange face corrosion inspection in raised face flanges.
  • RP concerning the application of statistical analysis techniques to NII inspection data.
  • Good practice guide on offshore composite inspection.
  • Review of technologies for shallow/splash zone and deepwater inspection.
