As a member of the APLNG Gathering Work Contractor panel Mitchell’s scope of works included the planning, design, manufacture, fabrication, assembly, construction (inclusive of general site clearance, construction of general civils, HDPE gas and water gathering systems, surface well pad infrastructure, fibre optic cable, HV and LV infrastructure works installation, testing and commissioning) in both Brownfield or Greenfield site environments for their well development programme.

APLNG is Australia’s largest producer of coal seam gas (CSG), supplying Queensland’s domestic gas market, as well as processing CSG into liquefied natural gas to meet growing export demand. Exploration for CSG in central and south west Queensland extends through the Bowen and Surat basins, with nearby towns including Roma, Chinchilla and Miles.

Roma West 2B Gathering Project

This particular section included gas and water gathering pipelines, along with the added complexity of installation of HV & FOC reticulation, often commingled within the trenches with the PE Gas & Water pipelines.

Pneumatic testing was progressively completed in five defined sections, allowing a sequenced handover of the asset to commence early gas extraction.

Completed on time and on budget, with zero defects, despite significant challenges of slow rock excavation and inclement weather.

Carmichael Rail Network

Carmichael Rail Pipeline

The Carmichael coal mine is located in the north Galilee Basin, Queensland, approximately 280km south of Townsville and 300km west of Mackay. The work scope included the construction of a water pipeline and procurement of associated pumping equipment & water storages.
