Santos Gladstone Liquefied Natural Gas (GLNG) completed the first phase of gas field construction after all three major natural gas compression hubs became operational, bringing the project closer to its goal of first production in 3Q 2015.

The achievement comes after testing of the third and final hub, near Roma, was completed and handed over to the long-term operations team, Santos GLNG said.
Santos GLNG’s has three major gas processing hubs: two in the Fairview field north of Roma, and one northeast of Roma. Natural gas and water from surrounding coal seams is piped to the three hubs via gathering networks.
The water is removed and re-used, and the gas is compressed and sent on to the pipeline compressor station where it is fed into the 420km gas transmission pipeline to Curtis Island, near Gladstone.
Together, the three hubs required 2900-tonne of steel, 21,700 cu m of concrete, 1050km of cabling, and 105km of pipework, and service an area of approximately 7000sq km. At nameplate capacity, the hubs will be able to process 555 terajoules of gas per day, the equivalent daily consumption of more than 9 million homes.
“The construction and commissioning of these three major hubs is a significant milestone on our pathway to first LNG production around the end of the third quarter of this year,” Trevor Brown, Santos VP Queensland said. “Our gas field facilities are complete, our wells are performing strongly, our pipeline is supplying gas to our LNG plant, and we’re approaching 95% completion overall.”
Work on the hubs began in 2012 and required 18.6 million work hours to complete construction and commissioning.
The US$18.5 million development, located on Curtis Island in Queensland, Australia, will convert coal seam natural gas to LNG for export to global markets. The project involves the development of gas fields in the Bowen and Surat basins, the construction of a 420km underground gas transmission pipeline from Roma to Gladstone, and a two-train LNG processing facility on Curtis Island, Gladstone.
In April, the joint venture confirmed the GLNG start date in which first production of LNG will kick-off at the end of 3Q 2015.
Natural gas first began to flow at the GLNG plant in March.
