Storage field is automated with open-architecture system

Modernization and automation of an operating gas storage field's SCADA system recently was accomplished by Pacific Gas and Electric Co. (PG and E) at its McDonald Island facility, 70 mi east of San Francisco. Operating people were brought aboard from the start and the choice of an open architecture control and communications system has produced both foreseen and unforeseen benefits. The modernization plan had two purposes: to install a SCADA computer system that restored all the original system's data monitoring and control functions at the withdrawal stations; to install a redundant graphics display system that would allow operators to monitor and control all three stations from any one station. The new control system also had to collect data from remote wellsites and include sufficient capacity for a 50% input/output (I/O) expansion, all while providing offsite monitoring using modems or the existing LAN/WAN corporate data network. The project's unique requirements challenged both cost control objectives and the critical need to keep operating personnel happy and cooperative with the new control architecture and operator interface formats. Simultaneously, the upgrade offered an opportunity to address some of the data communications issues facing PG and E in today's environment of shared data networks.
