Gisborne was contracted by Valmet to remove the internals in an existing digestor and then install new ones at the Zellstoff Celgar Pulp and Paper Mill located near Castlegar, BC .  The removal and installation of the digestor parts was to take place during a scheduled shutdown of the mill.  There were approximately 1000 workers taking part in hundreds of simultaneously scheduled shutdown projects.

Scope: Gisborne cut out all the existing digestor panels and plates from within an existing 200 foot tall tank and removed the parts through a 30" manhole. Gisborne also cut in 14 new nozzles, 10 and 6 inches each, in to the existing tank walls that were over 2 inches thick. 84 new digestor panels and screens were then installed inclusive of over 2000 lineal feet of welding.
