  3. Business Value – Asset optimization using PI and AF The Challenge: Optimizing the performance ofour fleet of gas compressors in service at 100stations over 14,000 miles of pipeline “Never in the history of our business have we needed to optimize how our assets perform as much as we do in today’s business environment. At $10 an MCF for gas for fuel for our compressor stations we spend $600MM US Dollars a year.” Customer Business Challenge Central Diagnostic Monitoring and Analytics Results / Benefits • Performance Measurement • Real Time Discovery of Performance Degradation • Unit to Unit Comparison • Centralized Diagnostic Monitoring • Transform NGT&S Operating Expertise into PI Analytics • KPI Dashboards • Reduction in Compressor Engine Fuel Consumption • Increase in Compressor Engine Operating Range • Improved Compressor Engine Reliability

  9. Compressor Station Fuel – KPIs (Concept)

  10. Energy Cost – (CF$/mcf)*(7350BTU lhv/BHP hr)*(1cf/1000BTU hhv)*(1BTU hhv/0.915BTU lhv) *(BHP)*(1mcf/1000cf)

  11. KPI - Model Heat Rate/Actual (PI-AF)
