© 2008 Capstone Turbine Corporation Example Applications
© 2008 Capstone Turbine Corporation Cathodic Protection Example Installation by Pumps & Service Client – Major US Gas Transmission Company Project - Gas Pipeline Cathodic Protection Requirements - Customer required extremely reliable power source at low current in very remote applications. Alternative Solutions Grid power – would require several miles of power lines installed Recip Generators – would require regular maintenance intervals Thermal Electric Generators (TEG) – unreliable
© 2008 Capstone Turbine Corporation Cathodic Protection Solution – Single C30 installed along pipeline as required Benefits Minimal maintenance requiring site visits only once each 6 months Remote monitoring and diagnostics to verify operational quality Extremely low emissions for installation in national forest
© 2008 Capstone Turbine Corporation Primary Power for Remote Site Example Installation by Pumps & Service Client:Major US Production Company Project:Primary Power for Salt Water Disposal Requirements:Needs reliable, cost-effective power in remote location Alternative Solutions Grid Power – Not available Re-Power – Eventually same problems with high maintenance cost, high emissions, and excessive down time. Reciprocating generators – Same as re-power
© 2008 Capstone Turbine Corporation Primary Power for Remote Site Solution - Multi-pac of 3-C30 installed in a control room fabricated for this site. Benefits Lowered maintenance cost Improved reliability of site Improved flexibility to control and maintain pressures and flow rates P&S Later designed New SWD in 2006 with Capstone because of success
© 2008 Capstone Turbine Corporation Primary Power for Oil Pipeline Example Installation by Pumps & Service Client:Large US Oil Pipeline Project:Transfer pumps for a major Oil Pipeline in Remote Location Requirements:Reliable Power because of extremely high cost for down time as well as being on a very remote location Alternative Solutions Grid Power – Not available Reciprocating Generators – regular maintenance schedules, unplanned down time (low oil, high engine temp..) and reliability.
© 2008 Capstone Turbine Corporation Primary Power for Oil Pipeline Solution:(15) C65 installed as the power supply for location Benefits: Minimal maintenance requiring planned site visits on semiannual schedule Remote monitoring and diagnostics to verify operation Reliability. No unacceptable downtime
© 2008 Capstone Turbine Corporation Offshore Resource Recovery The Solution: A Capstone microturbine, UL certified for hazardous oil and gas applications The microturbine runs on onsite unprocessed wellhead gas which is normally flared, providing a power source to the platform The microturbine cut maintenance time by ~95% compared to reciprocating engine generators The microturbine ran almost non-stop for 25,000 Capstone has microturbines running on other platforms in the Gulf of Mexico, Gulf of Alaska, Bay of Campeche, the North Sea, Mediterranean Sea, and South China Sea The Issues: Provide a reliable power source in a hazardous oil and gas application on an offshore platform in the Gulf of Mexico Recover value from onsite flare gas which is normally lost to the environment
© 2008 Capstone Turbine Corporation Offshore Installations Deployed in the Gulf of Mexico
© 2008 Capstone Turbine Corporation Conclusions Ideal power generation for oil & gas installations, onshore and offshore More than 5,000 Capstone MicroTurbines sold and 19+ million operating hours Fuel Gas from 350 BTU – 2500 BTU with up to 7% H2S Low emissions of less than 9 ppm NOx Lowest maintenance cost of $/kWh with 6 hours/year of planned maintenance No lubricants or coolants
