APLNG completes LNG tank testing

Published by

Australia Pacific LNG has completed the hydro and pneumatic testing on its second LNG storage tank, a first for Curtis Island.

Australia Pacific LNG's two 160 000 m3 storage tanks took two months to test and complete.

The LNG tanks were constructed by Bechtel and CBEtl.

It will take approximately three days to fill each LNG tank, once both of the LNG trains are in operation in 2016. It will take approximately 12 – 14 hours to load each LNG carrier.

The completion of testing of the LNG tanks plays a critical role in the delivery of first LNG exports in mid-2015, with gas from the Surat and Bowen basins delivered to Curtis Island through the pipeline system where it will be liquefied and shipped to Asia.

Page Maxson, Australia Pacific LNG CEO, said: "What sets the Australia Pacific LNG job apart is that the testing on both tanks was done back to back, and that in itself is a world-class achievement.

"We also undertook hydro and pneumatic testing simultaneously; a process that is usually conducted separately and has therefore saved us time."

LNG tank testing takes up to 26 days per tank and requires filling the tanks with water to test its integrity, quality and stability. Pneumatic testing is carried out to confirm the tank is 'gas tight', and to test the pressure and vacuum release valves.
