Acoustic Emission Monitoring

Operators face constant pressure to maximise productivity while keeping costs down. Maximising asset utilisation and minimising expensive inspections is one way to keep costs under control.

Technologies that monitor assets effectively while avoiding major shutdowns have become essential tools for operators. Advanced technologies such as Acoustic Emission Testing enable you not only to diagnose issues, but assess inherent risk - and optimise service through proactive management strategies.

  • Effective Inspections
  • Cost Savings
  • Technology that addresses integrity, regulatory, safety & environmental concerns


Reasons to Use AE

  • Global inspection of the entire structure
  • Minimal cost
  • Asset remains in service
  • Early and rapid detection of a wide variety of defects e.g. corrosion, cracks, delaminations, disbondment
  • Only active flaws/defects are detected
  • Defects are located and can be characterised
  • Minimal pre-inspection preparation
  • Results used to identify and prioritise maintenance according to risk (e.g. tanks with high active corrosion rates or leaks)
  • Inspections of difficult-to-access areas and Corrosion Under Insulation (CUI)
  • Monitoring of in-service defects under differing operating conditions
  • On-site or remote monitoring
  • Sensors can be directly mounted on test specimens, or placed at distanced locations remote from the defect
  • May be used in accordance with high temperature processes as well as cryogenic vessels


Applicable to:

  • storage tanks, either atmospheric or pressurised.
  • Spherical Tanks
  • Fiberglass Reinforced Plastic (FRP) Tanks
  • Compressed-Gas Cylinders
  • Larger pressure vessels
  • LPG bullets
  • seamless steel gas cylinders, either fixed or portable installations
  • Pipelines
  • Bridges
  • Elevating Work Platforms (EWPs)
  • Ships


AE monitoring is recognised globally through various networks of Australian and International Standards, Pressure Vessel Codes and ASTM test methods.
