Improvement Maintenance Work at Aperam

Aperam is a global player in stainless, electrical and specialty steel, with customers in over 40 countries. Aperam has 2.5 million tonnes of flat Stainless and Electrical steel capacity in Brazil, Belgium and France, and is a leader in high value specialty products. Aperam has a highly integrated distribution, processing and services network and a unique capability to produce stainless and specialty steel from low cost biomass (charcoal).

The Challenge

Aperam has a Cold Rolling Plant at Genk (B). Here short line stops for preventive and non-urgent corrective maintenance are an important element in the asset maintenance strategy. PDM was asked to analyze the effectiveness and efficiency of maintenance work during stops of a major production line in this plant.

Main findings

PDM’s analysis of the effectiveness and efficiency of maintenance work during stops yielded the following main findings:

  • Scope items added after scope freeze of line stop
  • Limited status overview during execution
  • High administrative workload for the line stop coordinator
  • Limited planning of stop & restart activities.

Impact of these issues is that not all planned activities were executed, overrun of line start-up timing and quality issues in the execution of maintenance work.


PDM implemented the following solutions:

  1. Optimization coordinator administration
  2. Optimization stop & restart procedure
  3. Optimization planning.

Project Results

The improved way of working was tested during a line stop in April 2019 with the following results:
  • 98% Of planned activities executed.
  • Planner was more in control of the line stop.
  • Reduction of overrun (from 12% to 8%)
  • Potential identified for further improvement.

I see clear added value in what PDM has delivered, not only in the reporting but most of all in the way of working. Such an effort without any labor union fuss or disruption on the work floor is certainly not easy. The fact that this went smoothly is really a sign of the commitment and quality of PDM.
