GE Fanuc Automation , a unit of GE Industrial, is working with CH2M Hill, a multinational engineering firm and designer of Singapore’s Deep Tunnel Sewerage System, on one of the largest integrated SCADA systems in the world.
One of the project’s first centralised water reclamation facilities, the Changi plant, is configured with approximately 500,000 tags across an architecture of 50 nodes running the newly-announced Proficy iFIX 4.0.
CH2M Hill was retained in 1998 to complete a feasibility study and preliminary design for the plant. The company provided all detailed designs and tendering services including all structural, mechanical, electrical, instrumentation and control facilities.
“The iFIX SCADA application empowers the driver towards operational excellence across the entire range of functional areas of the plant,” said Jim Black, CH2M Hill’s information and controls systems technology discipline director, “including the deep tunnel system pumping stations, treatment process and solids removal.”
The completed solution features 50 iFIX SCADA nodes and 10 thin clients processing the 500,000 tags. Proficy Historian is utilised to manage the overwhelming amount of historical data that is used for compliance reporting as well as for ongoing plant improvement projects.
The Proficy real-time information portal and terminal services optimise access by a wide user base via standard web browsers. These CH2M Hill developed applications include integration of plant information systems, electronic operation and maintenance (O&M) manuals and computerised maintenance management system (CMMS).
The significant scope of this project fostered a cooperative environment between GE Fanuc and CH2M Hill. The unprecedented size of the system itself resulted in minor enhancements to standard product based on collaborative design evaluation.
The system comprises more than 150 Group Schneider controllers.
