Workshop CADE: Critic equipment and piping systems. Evaluation and upgrading by means of advanced engineering.

Next November Thursday 7th 2013, at 10:00, CADE will hold at hotel Eurostars Madrid Tower the workshop:



Integration of process and mechanical engineering capabilities allows, by the application of advanced analysis and simulation tools, the evaluation and upgrading of  critical equipment and piping systems along both design and operation stages.

Application of such advanced capabilities is usually aimed to increase performance of equipment and minimize construction and O&M costs, being the economic yield, the last objective of these services.


  • To improve the reliability and performance of the equipment and piping system. Economic balance.
  • To determine operational limits of critical equipment.
  • To evaluate integrity and remaining life.
  • To evaluate on-service failures. Root-cause investigation
  • Preventive measures and corrections

Who should attend

This event is aimed to Engineering Managers, Piping and Static Equipment Area Managers, Project Managers and O&M Managers, related to projects and operation of refining, gas, and petrochemical plants as well as thermal power stations.


By means of real study cases, the application field of the described methodology and its derived benefits will be shown, both technical and financially on:

  1. Design phase: to get optimized and reliable designs, or for those designs which standard design codes are not applicable.
  2. Operation phase: to evaluate potential of performance upgrading, prevent operational failures and  improve efficiency and availability of equipment and processes.
  3. Re-rating: design validation and evaluation of the impact in equipment/piping lifetime because of the redefinition of either their operative conditions or new process requirements.
  4. To evaluate operational failure causes or defining preventive/corrective measures. Fitness for Service.
