Delmeco replaced the crane control system and frequency drives for anode handling at Century Aluminium. The project involved upgrading an outdated Allen-Bradley PLC, HMI, and frequency drives, which were replaced with a Siemens S7 PLC, HMI, and Sinamics drives.

This crane is part of the 24/7 potline process. To avoid disrupting production, commissioning and testing activities were carried out during scheduled shutdowns.

The scope of work for the automation and electrical disciplines included:

  • Reading out the old software and converting it to Siemens TIA Portal

  • Programming and testing the new Siemens PLC

  • Replacing the PLC and frequency drives

  • Testing

  • Commissioning the new control system

Delmeco’s responsibility for this project was to rebuild, implement, test, and deliver the new crane control system fully operational.

Client: Century Aluminum is a producer of primary aluminum, with facilities in the United States, Iceland, and the Netherlands, employing over 1,500 people worldwide. One of the products manufactured at the Netherlands facility is anodes. Anodes are carbon blocks used as conductors in the electrolysis process for aluminum production.
