When any part of your supervisory control and data acquisition (SCADA) system is outdated or…
To improve site safety, increase output, and reduce operational costs, many mines are now looking to modernize manual, outdated, and obsolete systems. This was the case recently for a large magnesia mine in the US that was still operating its grind line manually. Since the mine was running each machine on the line locally and did not have a central supervisory control and data acquisition (SCADA) system in place, the process was inconsistent and not particularly safe for operators.
Even though the site knew it really needed to invest in modernization, like many mines, this site did not have a fulltime onsite engineer as one really was not required on a daily basis. However, without an onsite engineer, it was difficult to determine the status of the current system so that requirements for a new automated system could be developed. Therefore, it took several years to get the potential modernization project to a point where the site was ready to bring in a third party to assist. Since GTH engineers had already formed a relationship with this mine as we had built a few replacement panels and provided some OEM equipment and PLCs for other outdated control equipment onsite, it was a natural choice to bring us in as an engineering and system integration resource for this project as well.
At the beginning of this modernization engagement, we faced several challenges regarding how to determine the scope of work (SOW) for the modernization. Then, once the SOW was set, we designed the new system, but we ran into another distinct set of challenges as we incorporated the new modern and automated system into their manual process line.
