Siemens Gas and Power (Siemens) will supply three cryogenic boil-off gas (BOG) compressor trains for the Golden Pass LNG export terminal in Sabine Pass, Texas, USA. The export facility is a joint venture between affiliates of Qatar Petroleum and ExxonMobil and will be integrated into the existing Golden Pass LNG import terminal.
The US$10 billion export project includes construction of three liquefaction process trains, each with a nominal output of approximately 5.2 million metric tons per year, associated treatment, power and utility systems, and interconnections to existing import facilities and controls. Golden Pass will also make modifications to the existing facilities, expand the facility’s storm protection levee system, and expand other various safety and security assets.
Siemens’ scope of supply covers the engineering, manufacturing, and testing of the three, single-shaft centrifugal BOG compression packages, along with all installation and commissioning activities. Each of the compressor packages will be driven by a 6.8-MW electric motor. Manufacturing, testing, and packaging will take place in Duisburg, Germany.
Siemens will also supply all low-voltage electric motors and electric variable speed drives (1 to 200 hp [0.76 to 149 kW]), all medium-voltage (250 to 1500 hp [186 to 1119 kW]) electric motors, and steam turbine generator sets for the Golden Pass LNG export terminal.
