Condition Assessment and Remaining Life Analysis

 

Whether it be critical rotor components affected by published OEM "end of life" limits, or turbine section airfoils subjected to extremes of operating temperatures and environment, Eta Technologies LLC (Eta Tech) can provide expert inspections and analyses to assess components and recommend the path forward.

Eta Tech can offer state-of-the-art inspections on either a destructive or nondestructive basis to accurately assess component condition and answer your questions, such as:

• What damage mechanisms are prevalent on my parts, given my specific operating parameters?
• Could there be latent manufacturing defects present which could adversely affect part life?
• Is there significant metallurgical deterioration of my hardware not evident by visual or NDT inspections?
• Are my components capable of being refurbished, and if so, how many HGPI or CI intervals will they last?
• How are the coating systems I use working, and are there better coating systems commercially available for my specific operating conditions?
• Am I at risk running my components for the currently employed service interval?

Eta Tech can also manage and assist in providing analytical engineering studies to model the steady state and transient operating conditions of any given component. Conducting these analytical design reviews can provide or allow:

• A "sanity check" on the life limits posed by the OEM.
• The establishment of remaining life limits based on sensible (not overly conservative) safety factors.
• The disposition of findings from rigorous inspections.
• The establishment of critical flaw sizes as a function of location.

And through these efforts, a very important question can be answered - are the OEM’s recommendations for service intervals, component repair and parts life realistic, or geared toward selling new parts?
