GPA undertook its first major high pressure natural gas pipeline design project in 1998. Since then, we have been designing and building pipeline and compressor projects across Australia.
GPA is a key contributor to Australia’s pipeline industry with several gas transfer projects spanning the county. We have delivered pipeline design engineering, procurement and construction management (EPCM) services on major pipelines, including:
- The Northern Gas Pipeline
- Palm Valley
- Owen Springs Lateral
- Pine Gap Lateral
- Dingo Pipeline
- SESA, Mortlake
- SEA Gas
- Moomba to Adelaide Pipeline System (MAPS).
GPA have extended capabilities in, and can assist with pipeline services including design of CSG gathering networks, two phase pipelines, liquid hydrocarbon pipelines, sulphuric acid pipelines, CO2 and LPG pipelines, water and slurry pipelines.
GPA place importance on being at the forefront of research and knowledge for key issues facing the Australian pipeline industry.

GPA was engaged by Jemena to design the 623 km, $800 million Northern Gas Pipeline from Tennant Creek, NT to Mt Isa, QLD. The pipeline design project aimed to drive commercial exploration and development of NT gas reserves to meet the demand from the east coast gas market.
As well as being active members of the Australian Pipeline and Gas Association (APGA) and the Energy Pipelines Cooperative Research Centre (EPCRC), GPA have had engineers serving on the standards committee for AS2885, the APGA code of environmental impact committee, pipeline engineer training committee, SA Young Pipeliners Forum committee and pipeline composites reference group. These groups and committees ensure GPA remain at the forefront of research and knowledge for key issues facing our pipeline industry.
