Roma Brisbane Pipeline
gas discovery – significant milestones
17/09/2018 3
• Associated Group formed from 1951
to 1961
• Feasibility mid 1960: insufficient
demand →government influence
• Contracted 15 years: ~18TJ/d
→ Now with looping?
• American Involvement
1954: significant strike Roma
1961: gas to Roma power
station
1964: gas to Roma hospital;
Moonie oil pipeline
constructed
1965: feasibility gas to Brisbane
1967:contract Austral-pacific
fertilisers
1969: commissioned
Roma Brisbane Pipeline
gas pipeline industry - pioneer

• the pipeline details:
• diameter - DN250 (and DN300 metro)
• length – 440 km
• thin walled pipe
• coating – ‘over-the-ditch’ tape wrap
• adequate design? → Needed for an immature industry
