  • EDSE Technology

    The Electric Discharge Sampling Equipment (EDSE) was developed by our UK based partner in collaboration with international partners to aid in the condition and life assessment of components. The sampling of in-service components has long been seen as an effective way of determining actual material properties and sub-surface material

  • Portable SFM Technology

    The Portable Scanning Force Microscope (Integrity-Scanning Force Microscope) has been developed for early stage damage detection such as creep cavitation (especially in P91 & P92 steels) which will not be found using traditional replication techniques.…

  • Obikou

    Obikou is an on-site service for power, process and other high temperature plant and has shown to achieve creep life extension by a factor of about 4. It simply involves quickly reinforcing a potentially vulnerable or creep damaged pipe with multiple layers of thin high-temperature alloys strip that is wound/wrapped around a pipe thus halting/ reducing the development of creep damage….

AMCO Integrity Pty. Ltd offers expert services in the evaluation of petrochemical/process/ refining and power plant covering a range of potential damage mechanisms (and their interaction) including but not limited to:

  • Corrosion
  • Creep
  • Hydrogen Damage
  • Fatigue
  • Embrittlement

AMCO Integrity Pty. Ltd assesses the fitness for service of plant under operating conditions which can give advanced  warning of in-service failures. This can help the plant operators in reducing cost by avoiding costly  unplanned outages and at the same time minimize excessive maintenance or premature inspection.

AMCO Integrity Pty. Ltd has experience of using standardized approaches such as those outlined in API 579. Furthermore, we have initiated and led the development of some of the European approaches to fitness-for-service in addition to its extensive experience in life assessment.

We implements this assessment in a staged way as follows:


Preliminary Fitness-For-Service Assessment and Inspection


Implementation of the Inspection Programme.


Final Fitness-For-Service Assessment

Depending on the site findings, this may involve all three Levels (i.e. Levels I to III) of FFS  assessment, with Level III fitness being the most detailed calculational phase involving finite  element modeling to refine the stress analysis of the component investigated. This assessment may include evaluation of a wide range of damage mechanisms including  (but not limited to):

  • Loss in wall thickness
  • Defect assessment
  • Pitting corrosion
  • Creep damage
  • Crack growth assessment
  • Temper embrittlement
  • Hydrogen damage

Based on the conclusions of the FFS assessment, the plant components suitability for further service may be drawn. Where the condition of the plant does not allow for continued operation, AMCO Integrity Pty. Ltd can provide appropriate advice/ recommendations on safe operation, repair or replacement strategies.
