Australia Pacific LNG -- Queensland, Australia
In 2008, ConocoPhillips signed an agreement with Origin Energy to participate in a 50/50 joint venture that would be comprised of coal bed methane development, operated by Origin Energy, and a liquefied natural gas production project, operated by ConocoPhillips. The LNG plant is under construction at Curtis Island across from Gladstone in Queensland.
Darwin LNG -- Darwin, Australia
Startup: December 2005, Capacity: 3.7 MTPA
Darwin LNG is a single train facility with a unit capacity of 3.7 MTPA majority owned and operated by ConocoPhillips. To address environmental priorities of project owners and the host country, the Darwin facility was designed with several firsts, including being the first application of highly efficient aero-derivative gas turbines in LNG service. Additionally, DLNG was the first Optimized Cascade® Process facility to incorporate waste heat integration to improve process efficiency and inlet air humidification to enhance production during periods of low humidity.
Kenai LNG -- Kenai, Alaska

Startup: June 1969, Capacity: 1.5 MTPA

The 1.5 MTPA Kenai Alaska LNG liquifaction facility is wholly owned and operated by ConocoPhillips. The plant started up in 1969 and has achieved over 40 years of uninterrupted supply to Japanese customers. Kenai was the world’s largest plant when built, the first to serve the Asia-Pacific market, and the first to use gas fired turbines for process refrigeration. Since startup, the plant has achieved production efficiency in excess of 95 percent and turbine/compressor reliability of over 99 percent.
