The APLNG pipeline project, a joint Venture between Origin Energy, ConocoPhillips, and Sinopec, was a high profile business investment to transport gas from the coal seam gas (CSG) fields in the Surat and Bowen basins in south western and central Queensland, Australia to a new Liquefied Natural Gas (LNG) processing facility located at Laird Point on Curtis Island, off shore Gladstone. The FEED was conducted under an earlyworks contractor agreement, which enabled preliminary design and open book EPC pricing to be developed in parallel that would provide greater confidence on pricing for the Final Investment Decision (FID). The pipelines included a 360 km transmission pipeline of 42-inch diameter from a central hub to the LNG plant, and Condabri and Woleebee lateral pipelines, 56 km of 36-inch diameter and 70 km of 30-inch diameter respectively feeding in to the central hub. This is known as the Main Pipeline System and constructed under the Main Pipeline Contract (MPC) as an EPC by MCJV a Joint Venture agreement between McConnell Dowell Constructors and Consolidated Contracting Company (CCC) Australia. In addition, there is a High Pressure Gas Network (HPGN) or Infield Pipeline Works awarded to Nacap Australia Pty Ltd to construct approximately 170 km of various diameter pipelines, but predominately 450 mm diameter, and above ground facilities.
The project was challenging, not for the majority of construction as the terrain traversed is reasonably flat and agricultural apart from a small section in the calliope range, because it had a large number of stakeholders, was highly regulated, and had a high risk crossing of the Narrows close to the Great Barrier Reef
