Pow­ered up and ready to start

NT News - - BUSINESS -

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.
