Electrabel in Langerlo went searching for a partner to lift the preparation and implementation of their revisions to a higher level. The current situation in the energy market requires the focus to lie increasingly on the reliability and availability of the units. For revisions, this translates into an emphasis on quality and optimum working time. This is a major challenge for Electrabel. All the more so, because the organization has to carry out all of the maintenance work associated with a revision with 66% less own-personnel than in the past. To make this possible, more attention has to be devoted to good preparation. Using the Turnaround Readiness Assessment (TRA) method, PDM thoroughly examined the preparations and implementation of the revisions. The result was a comprehensive report including the observations of previous revisions, recommendations for future revisions, and a complete process plan comprising all best practices defined by PDM.
