5PM Drive and DCS replacement
5PM Drive and DCS Replacement for Existing Paper Machine in Wauna, Oregon.
Georgia-Pacific had an existing paper machine drive control and DCS system that had become obsolete and was no longer supported by the OEM. Lack of spare parts and vendor support presented a significant risk to reliable machine production at the mill.
How We Did It
The client’s upgraded systems were successfully installed and commissioned while meeting the project budget and schedule limitations. Our rigorous quality control procedures and attention to detail contributed to the overall success of this challenging project.
Harris Group provided a Class 10 scope and estimate, detailed design and construction technical support for the project.
This project was coordinated, constructed, and started-up over a one-year period with numerous short scheduled paper machine downs, avoiding loss of scheduled production. Field investigation was essential to support high quality design deliverables. Harris Group provided E&I construction specifications and maintained detail construction and startup schedule.
The project included 50 P&ID updates for undocumented changes to process control instrumentation that was discovered during the updating of loop diagrams and programming the new DCS system. We made revisions to existing documentation to update I/O terminals and addressing for approximately 250 discrete loop diagrams and 160 motor elementaries. Furthermore, Harris Group developed 45 new loop diagrams, an instrument index for new loops, instrument specification sheets for new instrument devices, equipment layout/location diagrams defining location of all new equipment and routing of communication cabling, control panel circuit schedule, bench-board operator interface panels, electrical one-line diagrams, and DCS System one-line diagram.
