The Dampier-Bunbury-Gaspipeline (English: Dampier to Bunbury Natural Gas Pipeline (DBNGP)) in Western Australia is with 1530 km length the longest gas pipeline in Australia and one of the longest in the world. With a pipe diameter of 660 mm, it also has the largest capacity of all Australian gas pipelines.

The pipeline extends from Withnell Bay on the Burrup Peninsula near Dampier to Bunbury in south-west Western Australia. It supplies liquefied natural gas from the North West Shelf . The Varanus Island pipeline joins the DBNGP about 135 kilometers south of Dampier .

history

When West Australian Petroleum Pty Ltd discovered the natural gas deposits on the North West Shelf in 1975 , the idea of ​​supplying Western Australia with gas with the Dampier-Bunbury gas pipeline arose and in 1979 it was planned. On August 16, 1984, the first gas flowed through the pipes. It was state-owned and was sold to Epic Energy , a consortium of US pipeline companies, which in turn sold it to Dampier Bunbury Pipeline LTD in 2004 , following the liberalist deregulation ideas . This is made up of company shares of DUET (Diversified Utilities and Energy Trusts) with (60% share), Alcoa (with 20% share) and Alinta (with 20% share).

Others

The capacity of the pipeline was initially 360  terajoules (equivalent to 11.52 million m³ of natural gas) per day and was expanded to 450 terajoules (equivalent to 14.4 million m³ of natural gas) in 1991.

In June 2008, the DBNGP was used to maintain gas supplies to Western Australia after the gas liquefaction facilities on Varanus Island failed for months due to an explosion and fire, which led to the gas crisis in Western Australia .

The DBNGP leads along the North West Coastal Highway and crosses it on the Yannrie River, east of the Kennedy Range National Park it overcomes the Murchison River at Mulla Mulla and then turns south, where it crosses the Midland Road east of Dongara .
