The $US20 billion ($A21.3 billion) project is to comprise two trains, with the second train to receive its final modules later this year.

“Milestones such as this demonstrate the expertise and dedication of everyone involved in the project,” Bechtel’s general manger LNG business Alasdair Cathcart said.

“With the modules now in place, work is underway to connect the individual parts of the production train in advance of testing them as part of the overall system.

“We are pleased with the progress and will continue to work with our customer to successfully deliver the facility.”

The first train is made up of 82 modules, which were built at Bechtel’s module yard facility in the Philippines before being transported to Curtis Island over 19 months.

Bechtel is the engineering, procurement and construction contractor for three LNG facilities on Curtis Island, GLNG, Queensland Curtis LNG and Australia Pacific LNG.

The close proximity of these projects makes the area the largest concentration of Bechtel work in the world.
