All three of Santos GLNG’s major natural gas compression hubs are now operational, marking the end of the first phase of gas field construction.
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 Vice President Queensland Trevor Brown said: “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.”
“This is a year of delivery for Santos GLNG. 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,” Mr Brown said.
Work on the hubs began in 2012 and required 18.6 million work hours to complete construction and commissioning. Importantly, work was completed with an excellent safety record.
Together, the three hubs required 2,900 tonnes of steel, 21,700 cubic metres of concrete, 1,050 kilometres of cabling, and 105 kilometres of pipework.
The three hubs service an area of approximately 7,000 square kilometres, and at nameplate capacity will be able to process 555 terajoules of gas per day, the equivalent daily consumption of more than nine million homes.
Santos GLNG is a pioneering joint venture between Santos, PETRONAS, Total and KOGAS to supply liquefied natural gas to global markets.
Santos GLNG has three major gas processing hubs – two in the Fairview field about two hours’ drive north of Roma, and one about 30 minutes’ drive north-east 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 420-kilometre gas transmission pipeline to Curtis Island, near Gladstone.
