Siemens has been awarded a contract to supply an initial 10 compressor trains for the Magnolia LNG project in the US.

Siemens will supply refrigeration and feedgas booster compressors, and has also entered into an alliance agreement for future procession compression equipment and drivers with the project’s parent company, Liquefied Natural Gas Limited (LNGL).

“We are pleased that LNGL has awarded us with the supply of the main compression equipment and drivers for the Magnolia LNG project,” said Lisa Davis, Member of the Managing Board of Siemens AG.

“LNGL’s modular construction approach represents a very strong platform in a growing market. Our solution offers best-in-class emissions performance, space saving design and lower expected lifecycle costs.”


LNGL is developing an up to eight million tons per annum (mtpa) mid-scale LNG facility based on its OSMR® LNG technology in the Port of Lake Charles, Louisiana.

The project serves to liquefy natural gas for export from the US, as well as potential domestic use.

Siemens’ scope of supply comprises a total of eight refrigeration compressors and two feed gas booster compressors for the initial two LNG trains. Four Mixed Refrigerant (MR) Siemens STC-SV compressors will each be driven by a Siemens SGT-750 gas turbine, while four Ammonia Refrigerant (AR) STC-SV compressors will each be driven by a Siemens SST-600 steam turbine. Additionally two motor driven feed gas booster compressors will be delivered.

The subsequent two LNG trains necessary to achieve the full eight mtpa for Magnolia would bring the total number of compressor trains to 20 at this site.

In parallel, Siemens has further agreed with LNGL to establish a supplier alliance agreement (SAA) for process compression equipment and drivers for future LNGL projects in support of the company strategy to standardise the implementation of the OSMR® LNG technology worldwide.

According to the latest World LNG Factbook from Petroleum Economist, the LNG industry has now entered a period of growth with the start-up of many sources, following four years of flat supply.
