TCH requested PDM

  • to analyze the current Way of Working with regard to Turnarounds
  • to identify existing good practices in relation to structures and processes
  • suggest possible improvements in the organization
  • Management & Control, scoping/planning, Scheduling and SHEQ

PDM has helped us significantly with the Turnaround optimization, and we benefitted through their expertise and methodology in Turnaround optimization processes. The practical approach of PDM resulted also in the buy in of the people on the floor which is essential for implementing optimizations.
