DCP Midstream has recently upgraded the turbine and compressor control systems at their Goldsmith Texas Gas processing plant. These upgrades included replacing the original OEM controls on two GE LM2500 turbines, and two Demag/Delaval 4 section centrifugal compressors to increase reliability, efficiency, simplify operation and streamline maintenance and support requirements.
This paper describes the process used to qualify the need to modernize the controls replacement control systems assessment, and the turnkey vendor evaluation and selection. Project scope development, implementation, results and benefits derived from the system upgrades are also discussed.
The plant downtime for the whole project was minimized to 10 days and this included the successful commissioning of the plant that was completed in April 2011. The project significantly improved the overall plant availability and reliability.
