The contract comprises two 38,000 hp RB211-6562 DLE (Dry Low Emissions) mechanical drive packages and one RB211-6761 DLE compressor set rated at 44,500 hp.
The two RB211-6562 units will replace two Rolls-Royce Avon-powered packages that have been running at the Bright compressor station since 1974. Included in the contract are new rotor bundles for the two Rolls-Royce RFBB36 centrifugal pipeline compressors currently powered by the Avon units. An existing RB211 compression package, installed in 1990, will also continue to operate at the Bright station.
The RB211-6761 gas turbine will power two Rolls-Royce RFBB42 pipeline centrifugal compressors in tandem, and will be installed at the Dawn compressor station alongside five RB211 compression packages that have been operating at the station since as early as 1978.
The gas compressor packages will be delivered in the third quarter 2008.
