THE APLNG project on Curtis Island has reached the halfway mark of construction and is on schedule to deliver gas by mid-2015.
David Baldwin, Origin chief executive LNG, said the company had made significant progress in the construction of its Curtis Island plant.
"The delivery of Australia Pacific LNG is one of Origin's key priorities and the project remains on track for first LNG by mid-2015," he said.
In its quarterly report, Origin reported civil construction on Curtis Island was 76% complete, the accommodation camps and facilities had been completed and occupied during the quarter, and the core LNG tank floor and wall structures were progressing on schedule.
Ferry operations to carry workers had started between the Fisherman's Landing northern extension and Laird Point, and all dredging required for construction access had been completed.
Steel deliveries to the modularisation facilities started in July 2012, module assembly began as expected in September, and other key deliveries to the facilities were received as planned.
Last week Origin finalised a long-awaited deal with the Santos-led Gladstone LNG project, which will result in the two operations sharing some infrastructure.
APLNG is owned by Origin, ConocoPhillips and Sinopec, while GLNG is owned by Santos, Total and Korea Gas.
