Paper Machine Improvement & Headbox Replacement 2017-10-13T15:39:42+00:00

Project Description

HEADBOX REPLACEMENT

Greenberry was contracted by International Paper to replace and/or upgrade multiple approach piping and mechanical systems, a new primary and secondary headbox, and new slitting equipment on an existing, fully operating containerboard, paper machine. Greenberry was tasked to complete the pre-shutdown as well as the shutdown installation, commissioning and start-up support of all new equipment and piping systems.

This project had to be completed with minimal downtime. The required pre-outage work had to be completed in order to be ready for the shutdown during which the paper machine would receive its largest overhaul in decades. The largest component of the project was the installation of the new primary headbox. The new headbox was set behind the existing one which allowed installation and partial commissioning of the system without a machine outage.

Greenberry’s participation in the project started almost 2 years in advance of the final outage. Large phases of the project were sequenced and planned in detail and then completed with very little plant interruption.

The culminating, paper machine outage was completed over a 15 day window. Greenberry manpower totaled 160 employees with another 50 directly subcontracted individuals.

The complexity of this project centered on the need for the machine to keep running while minimizing the downtime leading up to the final machine outage. Greenberry provided a strong team with the foresight to see what could, and just as importantly, what couldn’t be safety completed “on the run.”
