Residual Life Assessment of structures and equipment

Problematics, relevant references, and good practice for evaluating the Residual Life of your machines and of various equipment

In the industrial world, there is a very large number of structures, machines, or components for which Residual (remnant) Life Assessment (RLA) is needed.

When an equipment/structure has reached its finite design lifetime, its owner must ask himself crucial questions, such as:
– Can I continue to use it as it is now and without danger?
– And, if so, for how much longer?

This Webinar gives an overview of existing references applicable to RLA and presents Cetim’ s methodology, with few application examples.

Topics covered during the presentation:

Features presented from case studies:

  • Context
  • Ageing of equipment
  • Proof of fatigue strength of steel structures in Europe: Eurocodes
  • Crane design, residual life of cranes and related Rules and Standards
  • Pressure vessels and boilers
  • Cetim’s general methodology for evaluation of Residual Life
  • Some industrial examples
  • Questions answers



The webinar will be presented by our experts Mr. Bruno DEPALE (Structural Analysis Expert) and Ms. Judy Goh (RBI/RLA Consultant), both supported by Mr. Cyril TRUNET.

Bruno is Structural Analysis Expert of CETIM (Technical Institute of the French mechanical industry). He works mainly in the fields of machine design, steel construction and has expertise in a wide range of machines, but with a focus on cranes. Since 2004, he has been French delegate in the working groups of CEN/TC147 and ISOTC96 dealing with Crane design.
His fields of interest cover structural analysis based on FEA (Abaqus), private studies dealing with proofs and strength of structures or mechanical components, projects dealing with RLA (Residual Life Assessment) of structures/machines and training for knowledge transfer to industry (87 sessions).
