Powered up and ready to start
INPEX has successfully started its LNG project’s power plant.
Ichthys Project managing director Louis Bon said it was a significant milestone.
“The combined cycle power plant uses gas and steam turbines together to produce up to 50 per cent more electricity from the same amount of fuel compared with a traditional simple-cycle plant,” he said.
“Initiating the safe start-up of the gas turbine generators illustrates the strong commitment of the onshore team to overcome challenges and achieve our targets.”
There had been questions as to the likely delivery timelines due to a major contractor dispute earlier this year.
Power and Water Corporation provided the initial gas to fuel the GTG start-up process.
The waste heat from the gas turbines will be used to create steam for the nearby steam turbine system, which generates extra power.
Ultimately powered by natural gas from the Ichthys Field, the CCPP will use a mix of five gas and three steam turbine generators to supply all the electricity requirements for onshore processing of LNG.
The power plant has capacity for up to 490mW of electricity, which allows LNG processing trains to cool and liquefy natural gas. “With more than 50 per cent energy efficiency, the CCPP will provide energy efficiency well above the 30 to 35 per cent typically achieved by a standard industrial gas turbine open cycle power plant and will allow the project to use saved fuel gas to produce more LNG,” Mr Bon said.
“Importantly, greenhouse gas and other air emissions from the Ichthys LNG Project will be significantly reduced through the use of combined cycle technology.”
Once operational, the LNG project will have the capacity to produce up to 8.9 million tonnes per annum of LNG.
