Pipeline scada upgrade uses satellite terminal system
In the recent automation of its supervisory control and data acquisition (scada) system, Transwestern Pipeline Co. has become the first to use very small aperture satellite terminals (VSAT's) for scada. A subsidiary of Enron Interstate Pipeline, Houston, Transwestern moves natural gas through a 4,400-mile system from West Texas, New Mexico, and Oklahoma to southern California markets. Transwestern's modernization, begun in November 1985, addressed problems associated with its aging control equipment which had been installed when the compressor stations were built in 1960. Over the years a combination of three different systems had been added. All were cumbersome to maintain and utilized outdated technology. Problems with reliability, high maintenance time, and difficulty in getting new parts were determining factors in Transwestern's decision to modernize its scada system. In addition, the pipeline was anticipating moving its control center from Roswell, N.M., to Houston and believed it would be impossible to marry the old system with the new computer equipment in Houston.
