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.

Tungamah Pipeline Project

A major challenge on the project from the outset was the resistance of several key Landowners to joining the scheme threatening to derail the project. Face to face meetings between the Landowners and Managing Director Wayne Mitchell established Landowner consent for the 40km of pipelines to be constructed through their properties, with access points omitted pending resolution of Water Authority issues.
