PROJECT NAME Australia Pacific LNG Pipelines

LOCATION Queensland, Australia

CLIENT Australia Pacific LNG Pty Ltd. (APLNG)

SCOPE Engineering, Procurement, Construction & Commissioning of a 530 km main gas pipelines and 150 km of smaller size pipelines.

DURATION 34 Months

DATE OF COMPLETION May 2014

Main Gas Pipelines Construction & Commissioning

Australia Pacific LNG delivered one of the largest coal seam gas (CSG) to liquefied natural gas (LNG) projects in Australia. A key component of the project was the construction of a 530 km main gas transmission pipeline and approximately 150 km of smaller size transmissionpipelines that will transport CSG from the gas fields in the Surat and Bowen Basins to an LNG processing plant on Curtis Island, in Gladstone where it will be processed for export to international markets.

The predominantly 42” (1050 mm) high grade steel pipeline will deliver 1560 Terajoules of gas to Gladstone every day. The smaller diameter pipelines will range in size from 18 – 36” dia. (450 – 900 mm).

The contract was awarded to McConnell Dowell/CCC Joint Venture (MCJV) and the scope of works involved Engineering, procurement and construction of pipelines and facilities from the Surat Basin to Gladstone to the APLNG’s LNG process facility on Curtis Island.

APLNG worked with the MCJV from January 2010 to August 2011 in an integrated team environment to complete the Early Works scope of the project in accordance with the Early Works Contract. The Early Works scope included field development optimization, FEED, approvals and land access, scheduling, long lead procurement and pricing the EPC scope.

The entire 530 km high pressure main gas transmission pipeline became a single, continuous structure linking Curtis Island with the Condabri gas fields.

Through the dedication, commitment and collaboration between Australia Pacific LNG and CCC and its partner McConnell Dowell, the Environment Management team from Australia Pacific LNG received an Australia Biosecurity Award.
