- Who uses the DBNGP pipeline?
- The majority of the natural gas transported by the pipeline is consumed by major industrial users in the mining and minerals processing industries, but it also supplies gas to power generators and gas retailers. The DBNGP was constructed in stages between 1982 and 1985 by the State Energy Commission (SECWA).
- When was natural gas introduced into the DBNGP?
- Natural gas was introduced into the pipeline in 1984 when the first stage stretching from Dampier to Kwinana Junction was commissioned with throughput of about 240 TJ/d. In 1985 the pipeline was extended to Bunbury. The DBNGP has been in continuous operation ever since.
- When did SECWA start supplying natural gas to Bunbury?
- In 1985 the pipeline was extended to Bunbury. The DBNGP has been in continuous operation ever since. As well as funding the pipeline project, SECWA was the foundation contract for the new supply of natural gas. SECWA entered into a long term contract with the North West Shelf Partners to purchase fixed volumes of gas.
- What is the longest natural gas pipeline in Australia?
- The Dampier to Bunbury Natural Gas Pipeline (DBNGP) is the longest natural gas pipeline in Australia. It is 660 millimetres (26 in) in diameter, which also makes it one of Australia's largest in terms of transmission capacity. At the time of its commissioning in 1984, it was one of the longest gas pipelines in Australia.
