PLANNING, DESIGN, AND EXECUTION OF AN AUTOMATION SYSTEM REPLACEMENT DURING A SCHEDULED OUTAGE

摘要

Many mills are contending with aging and multigenerational control systems that are failing or obsolete. Most mills only have their scheduled annual/biennial/triennial outages to tackle the necessary improvements to these systems. The amount of work needed, the critical importance of the systems involved, and the looming risk of an extended outage - along with the potential for lost revenue - all add to the daunting task. This paper will discuss a specific project executed to update the instrumentation, DCS controls, burner management system, and associated electrical infrastructure for a recovery boiler at Georgia-Pacific's Camas WA mill, with all construction and commissioning successfully completed during a scheduled two-week outage. This paper will describe techniques, practices, and activities used throughout the planning, design, and execution of the project, will share pit-falls and lessons learned, and will highlight the importance of teamwork between the Owner, the Engineer, and the Contractor.
