Residual Life Assessment

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

Because when an equipment/structure has reached its finite design lifetime, its owner has to ask himself crucial questions, such as “Can I continue to use it as it is now and without danger?”

This webinar deals with this issue and provides keys, considering that most of the standards are intended for design only and not for the extension of the service life-time of old equipment.

Features presented from case studies:

  • This webinar gives an overview of existing references applicable to Residual Life Assessment for steel construction and cranes.
  • It also presents the RLA methodology of Cetim Group (Technical Institute for Mechanical Industry), with few industrial application examples.
  • Questions answers





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 French experts Mr Bruno DEPALE (Structural Analysis Expert) who work in the business unit of Simulation and Judy Goh Zhu Di (Matcor Consultant)


Bruno is a 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).
