A five-day shutdown secures the digital future of Opal Maryvale mill

Opal Australian Paper and ABB have successfully upgraded the Maryvale mill's distributed control system in a record eight-week project.

A strategic shift demands a robust digital foundation

The Maryvale Mill in Victoria has been a cornerstone of Australian paper manufacturing since 1937. However, the facility has undergone a profound transformation in recent years. Following the cessation of white paper production in 2023 due to timber supply constraints, Opal Australian Paper pivoted the site entirely toward the growing fibre packaging market, focusing on unbleached kraft linerboard, fluting medium, and sack papers. In 2026, operating a competitive packaging mill requires more than just raw material; it demands absolute operational reliability. To secure this, Opal has partnered with ABB to execute a critical upgrade of its distributed control system (DCS).

Executing a mill-wide upgrade in record time

Upgrading a DCS in an operational mill is notoriously complex, often fraught with the risk of extended downtime. Yet, Opal and ABB managed to deliver a complete mill-wide automation upgrade in just eight weeks of planning and preparation, culminating in a tightly controlled five-day shutdown window. The project transitioned the mill's existing ABB Ability System 800xA platform from version 5.1 FP4/E to the latest commercially available release.

This was not a mere software patch. The scope of work encompassed a full system version upgrade across the site's entire automation infrastructure. It included operating system upgrades for servers, client workstations, storage systems, and network equipment. Furthermore, the engineering teams executed firmware upgrades for controllers and communication devices to ensure absolute system compatibility, stability, and performance across the newly modernized architecture.

The role of continuous software maintenance

A key enabler for this rapid deployment was Opal's active Automation Software Maintenance (ASM) Agreement with ABB. In the modern pulp and paper industry, treating automation software as a one-off capital expenditure is a strategic error. Subscription-based ASM programs provide continuous access to the latest software versions and lifecycle support. This proactive approach streamlined the upgrade process at Maryvale, mitigating compatibility risks and aligning with Opal's long-term automation roadmap.

Brad Burton, Pulp and Paper Industry Lead at ABB Australia, highlighted the operational synergy required for such a feat, noting that the success of the project reflects the power of strong collaboration, local expertise, and a shared commitment to continuous improvement. By moving to the latest iteration of the ABB Ability System 800xA, Opal has established a modern automation environment. This foundation not only enhances current communication capabilities but also opens the door to future digital applications and advanced analytics available within the broader ABB ecosystem.

Positioning for the future of packaging

For the global corrugated and packaging sector, the Maryvale upgrade serves as a practical case study in asset life extension and modernization. As mills age, the risk of obsolescence in control systems becomes a critical vulnerability, directly impacting yield, energy efficiency, and product consistency. By executing this upgrade with minimal disruption, Opal Australian Paper has effectively future-proofed its primary packaging manufacturing hub in Australia, ensuring it can meet the stringent quality demands of the modern supply chain.

The transition from legacy systems to modern, integrated automation platforms is no longer optional for mills looking to maintain margins in a highly competitive global market. The Maryvale project demonstrates that with rigorous planning and the right technological partnerships, even the most deeply embedded control systems can be modernized swiftly and safely.

The seamless execution of this DCS migration proves that proactive software maintenance agreements are the unsung heroes of mill reliability, transforming daunting upgrades into manageable, routine operations. Will more legacy mills adopt subscription-based automation models to avoid the operational paralysis of outdated control systems?
