Project Overview:

Norske Skog, Australia’s largest newsprint producer, originally selected Mipac in 2002 and initiated an Automation Upgrade project to provide a new plant-wide control system and integrated automation platform. Consolidation of control system types and the replacement of obsolete systems to facilitate central control of the plant was the fundamental aim of the project.

Mipac Scope:

Mipac managed the design, implementation and commissioning of the new control system. This included the Paper Machine, Steam Plant, Water Treatment and TMP Pulp Mill. Mipac’s scope included:

  • Assisting in the selection of the new control system
  • Management of project design, commissioning and implementation
  • Development of specifications and standards for electrical, instrumentation and control scope
  • Detailed design for electrical, instrument and control requirements in all plant areas
  • Application programming for the Water Treatment Plant, Steam Plant and Paper Machine (Stock Preparation and Broke Systems)

Project Highlights:

  • Mipac managed a phased upgrade of the automation systems for the whole mill which included more than 15,000 inputs and outputs (I/O)
  • The project involved replacing the existing control system which consisted of Honeywell TDC 2000, TDC 3000, Siemens Programmable Logic Controller (PLC) and relay logic
  • Plant operators now have a single user interface, with improved control strategies and alarm management. This will increase productivity and ultimately, profitability
