Northern Gas Pipeline

Type of project: Gas Infrastructure

Client: Jemena
Location: Tenant Creek (NT), Mount Isa (QLD), Australia
Completed in: 2018

Spiecapag was contracted to deliver the 143km DN300 diameter steel gas pipeline and associated crossings, civil and mechanical works for the Queensland section of the NGP Project. The scope of work included a start of line receipt/compressor station, three Main Line Valve (MLV) facilities along the pipeline, an end of line delivery station, and five cathodic protection stations.

Due to land access restrictions at the Mount Isa (Eastern) end of the pipeline, Spiecapag was required to perform the works from west to east. This involved a full camp and laydown area to be constructed beforehand. The camp mobilisation and construction schedule was critical and Spiecapag pulled out all the stops to ensure this was performed in an expedient manner.

The project was originally planned to be built around the wet season, with 93km scheduled to be completed before the wet season, and the remainder as part as a remobilisation in March. Due to early access and high productivity rates, Spiecapag safely completed all mainline construction activities prior to the Christmas period, avoiding the need for the 2nd mobilisation in March.

Working in a remote part of Queensland, Spiecapag engaged extensively with local businesses, including indigenous communities, where job-specific training was delivered, leading to 24% of our workforce coming from indigenous communities.
