Cause of QCLNG vapour leak being investigated

UPDATE FRIDAY: A vapour leak on one of the LNG tanks on the QCLNG project on Curtis Island meant employees spent the morning in their crib rooms as a safety precaution.

It was detected by a monitor at 4.30am on Thursday.

Bechtel Gladstone general manager Kevin Berg said the cause was still being investigated.

"The vapour is from the LNG produced through the first production train and currently being stored in the LNG holding tank," Mr Berg said.

"It is currently understood to have originated from a flanged component in one of the LNG pumps in the tank, which in turn triggered a local gas alarm alerting the plant operations staff to take appropriate action," he said.

"The pump was powered down and isolated from the system, emptied of LNG and corrective action is expected over the coming days in working with the LNG pump supplier."

Employees had attended work as normal in the morning and received text messages about 6am about the situation.

The text message read: "A gas leak has been detected on Tank B and as a safety precaution we are asking that you please remain in your crib huts or offices until further notice has been given".

The workforce returned to normal duties after lunch.

In September there was an ethylene leak on the same project.

Then, workers were stood down for almost 16 hours.

The gas was safely vented via the flare stack.

THURSDAY: A vapour leak was detected on a tank on the QCLNG site on Curtis Island early this morning.

Employees have spent the morning in their crib rooms as a precautionary measure.

We'll bring you more details when they become available.

The site shut down for about two weeks from March 10 as part of the commissioning process of Train 1.
