Eastern Bechtel, prime contractor on Abu Dhabi Gas Industries’ (GASCO) Habshan gas plant expansion project, OGD-III, has awarded a major SCADA contract to Invensys Process Systems. The system is built around a Wonderware kernel configured for oil and gas applications. Foxboro Remote Terminal Units will be located at some 180 existing and new gas production wells, remote manifold stations and injectors. Approximately 10,000 I/O points throughout Habshan will be controlled or monitored by the new system, most on wells and remote manifolds.
The control room employs redundant master SCADA servers, a real time database and an InSQL historian. The servers are connected by redundant, high-speed Ethernet. The control room is linked to monitoring and control sites, including the nearby Bab plant.
The changeover to the new SCADA system will be implemented in parallel with the existing SCADA system during ongoing production operations at the Habshan processing facilities. Residue gas from processing is re-injected into the reservoir for pressure maintenance.
