Upstream Gas Gathering Down Under

Posted on March 24, 2011

Siemens Energy has received an order from Australia Pacific LNG (APLNG), Queensland, Australia, for the supply of 10 compressor trains. APLNG is a joint venture between Origin Energy and ConocoPhillips.

The APLNG project will involve the development of coal seam gas fields in south central Queensland over a 30-year period and includes construction of upstream gas gathering and processing facilities together with a 450 km main transmission pipeline from the gas fields to the LNG facility. The Siemens´ compression system will be incorporated into APLNG’s upstream gas gathering facilities to compress low pressure coal seam gas for delivery via the main pipeline to the LNG facility, whereupon it will be compressed and cooled into LNG. Delivery of the compressor trains will start in early 2012.

Each compression train consists of two compressor skids, one low pressure and one high pressure, with each skid carrying two compressors with variable speed drives.
