THE 80th and final module has been given a fitting farewell from Thailand as it begins its journey to the QCLNG project on Curtis Island.

The module will take three weeks to make its way to the project, where it will be rolled off the barge to the quarantine area for inspection before it takes up its permanent position as part of the Train 2 facility.

Modules have been sailing into Gladstone throughout the year, with QGC managing director Derek Fisher earlier this year saying the delivery was an amazing logistical feat.

"At year's end we will have received all 80 modular LNG processing packages for our first two production units, or trains," he said in April.
