  • Who owns Dampier Bunbury Pipeline?
  • * Dampier Bunbury Pipeline is the trading name of the DBNGP group of companies, ultimately owned by the consortium that purchased the Dampier to Bunbury Natural Gas Pipeline in October 2004. DBP is majority owned by DUET – Diversified Utility and Energy Trusts - with Alcoa and Alinta being minority owners.
  • 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).
  • Should DBP adopt a pipeline design based on a gas composition?
  • Kimber Consultants recommends that DBP should adopt a pipeline design that is based on a gas composition implied in the Recommended Design Gas Composition as shown in Table 4, which has a combination of the lowest expected heating value, a low Wobbe index, no LPG and modest levels of inerts.
  • What happens if DBP chooses a high quality gas specification/composition?
  • Conversely, if DBP chooses a high quality gas specification/composition and lower quality gas is shipped, then the pipeline’s increased capacity will be “under-designed” and DBP will not have the pipeline capacity to sell as a firm service and will incur penalties; and the incremental tariffs will not result in cost recovery – a double loss.
  • What is the average gas quality in a DBNGP?
  • Paradoxically, the results indicate that average gas quality will remain quite high and that there is a relatively low probability of receiving gas into the DBNGP with a heating value of around 37 – 38 MJ/m3, or with up to 7% inerts, except perhaps during some short term plant or field upset.
  • What is DBNGP corridor?
  • This land is now known as the DBNGP Corridor and remains State owned and managed today. After almost three years in planning, construction on the pipeline was launched in 1982. 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.
