GPA have broad experience in pipeline and facility design, simulation, construction management and commissioning. Our capabilities reach across CSG gathering networks, Gas Injection and Storage Facilities, two phase pipelines, liquid hydrocarbon pipelines, sulphuric acid and ammonia pipelines, CO2 and LPG pipelines, hydrogen pipelines, water and slurry pipelines, and liquor pipelines.

GPA engineers participate in and have served 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.
