|AngloGold Ashanti Australia – Sunrise Dam Citect SCADA Upgrade
|AngloGold Ashanti Australia
|AngloGold Ashanti, a global gold mining company with 21 operations on four continents, employed 65,822 people, including contractors, and produced 3.94Moz of gold in 2012. Sunrise Dam is located in the northern goldfields of Western Australia, 220km northeast of Kalgoorlie and 55km south of Laverton.
|To completely rewrite and migrate the legacy 5.X version of the Citect SCADA distributed application to a Citect SCADA 7.20 system. The new Citect application was to be built utilising the same look-and-feel as the new Citect SCADA system deployed at AngloGold’s new Tropicana Gold Mine. This migration would result in all of AngloGold’s operations in Australia utilising a unified Citect template with similar look-and-feel.
|KAPP provided the upgrade works where completely new client-server architecture was deployed on site to replace the existing architecture. The old system utilised individual Citect stations and the old independent architecture resulting in upgrades requiring restorations on all stations. There were also no dedicated Citect SCADA servers where operators were working on the actual servers.
The new architecture utilises headless primary and standby servers utilising Dell PowerEdge 700 series servers and distributed clients utilising Dell Vostro Workstations. The Citect SCADA application was further tweaked to block all access to the operating system thereby locking out access to USB ports and the operation system entirely. The new Citect SCADA project utilises direct pull methods where the clients automatically pull updated projects from the servers thereby not requiring any engineering intervention to the client stations when changes are made to the main SCADA projects. The all new P&ID style pages were engineered to reduce clutter and take advantage of the new widescreen displays.
The project was deployed with “zero” downtime to production where the old and new systems were run in parallel during the proving period. The old system has been completely phased out and the site is now completely running on the new version of Citect.
As part of this upgrade Citect Reports was also upgraded to the latest version of the Citect Historian product with all functionality ported over to the new system
