- Hydrogen Damage
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.
