WCL’s Meridian field development program highlighted a requirement for an expansion of their HDPE gathering network to realise additional production by lowering wellhead pressure and having the ability to re-route gas flow between the Moura Compression Station, the Moura Central Compression Station and the Nipan Compressor Station.

Mitchell was engaged on a Lump Sum EPC basis:

Engineer: including detail design of the pipeline alignments, profiles, road, waterway & service crossings, vents & drains, taking into account landholder constraints, endangered habitat and access issues, and SMS all to APGA CSG Gathering code.

Procure: including the purchase, transport, storage and correct dispatch of all materials and external services providers.

Construct: Install, test and commission the pipelines, and handover As Built GIS and complete MDR.

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.
