Siemens Gas and Power (Siemens) will supply two gas turbine compression packages for Midcoast Energy LLC’s (Midcoast) CJ Express pipeline expansion project in East Texas, USA. WHC Energy Services, supported by Universal Pegasus International, will be the engineering, procurement, and contracting provider for the pipeline expansion project.

Siemens will supply two SGT-400 mechanical-drive compression packages that are capable of producing a total of 39,000 hp (29,094 kW) for an expansion at an existing compression station. The SGT-400 gas turbine will be packaged at Siemens Gas and Power’s facility in Houston, Texas, while the compressors will be built at the company’s facility in Olean, New York, USA.

The first gas turbine compression trains will be shipped later this year to support commercial operation for early next year.

The CJ Express project will deliver natural gas produced in the Haynesville Shale formation into premium demand markets along the US Gulf Coast. The CJ Express will connect Midcoast’s existing pipeline assets in San Augustine County, Texas, and growing production in the Carthage and Shelby Trough area of the Haynesville Shale, to Midcoast’s Clarity pipeline near Silsbee, Texas. The project is expected to provide incremental delivery capacity for up to 1 Bcfd (28.3 x 106 m3/d) from the Carthage area to multiple Gulf Coast markets.

CJ Express will include up to 107 miles (172 km) of 36-in. (914-mm) pipeline and a 39,000 hp compressor station. Midcoast expects the expansion project to have an in-service date in early 2021.
