ALL three LNG sites on Curtis Island are ready to store liquefied natural gas, after Bechtel successfully completed hydro-testing on three of the six storage tanks.

Hydro testing is carried out to verify that each tank can hold its design capacity of LNG.

It involves filling a tank with seawater over several days, then letting the water sit for 24 hours to ensure the integrity of the tank foundations.

QCLNG and GLNG's tanks are capable of holding more than 140,000m3 of LNG, while Australia Pacific LNG's tanks each hold 160,000m3.

The QCLNG tank was the first to pass hydro testing in April.
