Diverse Welding Services complete Stage 2 of Project Bob


Perrigo Australia


Diverse Welding Services (DWS) has finished the second and final stage of the Project Bob Upgrade for Perrigo Pharmaceuticals.  This project commenced in March 2015, and ran in parallel with the building works within the production facility.  The project included major plant & equipment installation, process piping from external storage tanks of IPA & Ethanol to a TGA / FDA Approved Clean Room Manufacturing Facility; inter tank process lines in the mix room, through to two product transfer lines to the depositing lines. 


The upgrade has allowed the client to increase its batch sizes of production runs, through increased automation and storage capacity.  600 Autogenous welds later; we have been able to deliver our client a traceable, drainable process piping system in line with the ASME BPE design requirements, including passivation using Citrisurf 3050 and pressure testing of all lines.  Quality fabrication is only as good as the quality assurance requirements within the pharmaceutical industry & supported by Diverse Welding Services (DWS) validation package, we have given the client all the traceability it requires meet its auditory requirements as a pharmaceutical manufacturing plant.


Highlights of the installation included, fully enclosed pipework within the mix room & transfer line, allowing for reduced cleaning times & better cleanliness.  DWS completed the installation with one (1) critical plant shut down over 2 weeks.  Diverse Welding Services completed a comprehensive site survey & was able to prefabricate a large majority of the fabrication prior to the shutdown window.

Diverse Welding Services would like to thank Perrigo for the opportunity to complete this work, and looks forward to watching Perrigo move forward & grow based on its new plant and processes.
