Utah-based Questar Regulated Services (QRS) has selected ESRI software and implementation services for its enterprise GIS platform. As part of the overall solution, ESRI business partner GE Energy, will supply its pipeline industry specific applications and related services. This comprehensive solution will support the company’s Geospatial Pipeline Maintenance and Integrity Management Support project, which is designed to meet specific regulatory and compliance requirements. Phase one of the fast-track implementation is scheduled for completion by the end of 2004.
“We needed a system with powerful functionality to perform High Consequence Area (HCA) analysis, risk analysis, class location determination, Maximum Allowable Operating Pressure (MAOP) calculations, and other compliance and engineering functions,” says Mark G. Warner, director of engineering support and pipeline compliance, Questar Regulated Services. “Our initial focus and vision is to move all of our transmission pipeline data into the new ESRI environment and to consolidate data into one central repository where it can be accessed companywide by the people who need it, when they need it, and from wherever they need it.”
QRS is the parent company to Questar Pipeline Company (QPC) and Questar Gas Company (QGC). QPC maintains 2,500 miles of transmission pipeline across six states and QGC maintains 23,000 miles of distribution pipeline, serving more than 770,000 customers within 21,000 square miles of service territory.
The accurate and up-to-date digital asset and property records developed and maintained with the help of GIS technology will ensure optimized planning in response to the new regulatory compliance issues as well as network monitoring and maintenance, new construction, leak survey, cathodic protection, equipment inspection, outage response, and more.
The enterprise solution will initially deploy ESRI’s ArcEditor software as well as ArcSDE software for Oracle. The geodatabase and specifically the ArcGIS Pipeline Data Model will provide the basis for the central data repository. In the future the company may deploy ArcIMS for Intranet/Internet GIS and ArcPad software for mobile GIS.
