When mechanical installations are inspected or rehabilitated, machine components sometimes need to be replaced or modified.

In order to ensure optimal dimensioning,
HYDRO Exploitation uses the following range of procedures :

  • FEM calculations (verification, optimization or stress determination, for conventional remaining service life determination or fitness-for-purpose analysis)
  • Analytical calculations based on pressurized
  • equipment standards (dimensioning)

In addition of the calculation, the service also includes a full report which includes the input data, the procedure (assumptions and standards applied) and conclusions and/or recommendations.


    • gathering of the available information (consultation of archives etc.)
    • setting the objectives to be reached, the calculation method being defined in collaboration with the Customer (note that HYDRO Exploitation’s recommendations will be based on its own experience)
    • measurements of components as required
    • performing calculation, maintaining close contact with the customer in the event of variations from the defined procedure
    • analysis of results (with support from HYDRO Exploitation experts)
    • provide suggestions and recommend action based on the results of the calculation
    • preparing a technical report
