Sanctioned in January 2011, GLNG includes the development of CSG resources in the Bowen and Surat Basins in south-east Queensland, construction of a 420-kilometre underground gas transmission pipeline to Gladstone, and two LNG trains with a combined nameplate capacity of 7.8 mtpa on Curtis Island.
The project has an estimated gross capital cost of US$18.5 billion from final investment decision to the end of 2015, based on foreign exchange rates which are consistent with the assumptions used at FID (A$/US$ 0.87 average over 2011-15).
GLNG has sales and purchase agreements with PETRONAS and KOGAS for 7.2 million tonnes per annum of LNG in aggregate.
As at the end of the first quarter 2013, the GLNG project was over 50% complete and on track for first LNG in 2015.
Forty-nine wells were spudded in the GLNG acreage during the first quarter. This included 45 development wells and four appraisal wells – one of which encountered significant coals (70 metres net) in the Arcadia acreage. 19 development wells were spudded at Fairview and 26 development wells at Roma.
Construction continued at the three upstream gas hub sites and over 120 long-lead items had been installed. At Fairview Hub 4, foundations were completed for the nodal compressor station together with the lube oil coolers and scrubbers, and pond lining was installed. At Fairview Hub 5, lube oil cooler foundations were poured and installation of the underground piping was completed. At Roma Hub 2, foundation works on the nodal compressor station were completed and underground piping commenced.
Gas transmission pipeline
Development of the pipeline progressed during the first quarter of 2013. Over 180 kilometres of the mainland pipeline right-of-way had been cleared and graded and 140 kilometres of the pipeline had been strung. One manual and two automatic weld crews had been mobilised and had completed over 9,600 welds on the pipe of the 35,000 required. In March, the rehabilitation works commenced in the Arcadia Valley replacing original topsoil and sowing grass seed, with over 60 kilometres of pipeline buried.
For the marine crossing, the tunnelling machine had been assembled within the launch shaft and tunnelling works on the 4.3 kilometre tunnel underneath the Narrows Crossing commenced on 15 April. The tunnelling will take about 12 months to complete and once constructed, the tunnel will be flooded and the pipeline pulled through.
Construction continues to ramp up on the LNG plant and port, with a current workforce of over 2,000. Ships containing key equipment are now being received at the material offloading facility, with the Train 1 CO2 absorber and cold boxes arriving in March and the modules for the main electrical substation buildings for the LNG plant arriving in April.
Heavy-lifts are well underway on the Train 1 site, with all six refrigeration compressors, the ethylene and methane cold boxes and CO2 absorber placed on their foundations. At Train 2, the formwork on the compressor deck foundation has commenced and the concrete pours for the ethylene and methane cold box foundations have been completed.
Eight of the nine concrete wall lifts required for LNG Tank B have been completed, with preparations underway for the ninth wall lift. At LNG Tank A, assembly of the arched steel roof segments is underway and preparations continue for the fourth concrete wall lift.
Progress on the LNG jetty continued, with 10 of the 22 bents completed and 26 of the 35 jetty-head loading platform piles cut to level.
At the module yard in Batangas, assembly of 49 of the 82 Train 1 modules continues and 14 Train 1 modules are in the final stages of completion, with preparations underway for dispatch of first modules to site. Assembly has also commenced on two of the 29 Train 2 modules.
