Dampier Bunbury Pipeline (DBP) is the operator of the privately owned Dampier to Bunbury Natural Gas Pipeline, Western Australia’s most important piece of energy infrastructure. DBP does not produce, buy, sell or trade gas. Rather it transports it from the domestic gas producing plants on the Pilbara Coast to demand centres in the Pilbara and South West of the State.


As WA’s key gas transmission pipeline, the Dampier to Bunbury Natural Gas Pipeline stretches almost 1600 kilometres, linking the gas fields located in the Carnarvon Basin off the Pilbara coast directly to mining, industrial, commercial customers and via other distribution networks to residential customers.


While our principle role is the safe and reliable operatorship of the DBNGP, our expertise extends far beyond this. DBP is an experienced pipeline maintenance and integrity management operator, spending in excess of 112,000 hours on planned maintenance each year.


The pipeline has been in continuous operation since 1984, and has a remaining life of at least 50 years. The system consists of 27 turbine/compressor units located at 10 sites, which essentially push the gas through the length of the pipeline. The pipeline system has operated at 99% efficiency for the past 10 years.


DBP also provides design, project management and construction services to companies wishing to connect to the DBNGP for pipeline laterals, inlet connections and metering stations. In many cases, DBP is also chosen to provide ongoing maintenance and integrity services.


ABOUT the Australian Gas Infrastructure Group (AGIG):


The Australian Gas Infrastructure Group (AGIG) came together following the acquisition of the DUET Group by the CK Infrastructure Holdings led consortium, combining the operations of the Dampier Bunbury Pipeline (DBP), Australian Gas Networks (AGN) and Multinet. AGIG’s origins date back almost 150 years to the gas distribution networks of the former South Australian and Brisbane Gas Companies, and the Gas and Fuel Corporation of Victoria.


The group has a long history of gas pipeline ownership with about 23,000km of natural gas distribution networks and over 3,000km of transmission pipelines across Victoria, South Australia, Queensland, New South Wales, Western Australia and the Northern Territory.


Additionally, AGIG is an active participant in the development of significant regional pipeline opportunities. Leveraging off a large and mature infrastructure business, AGIG has engineered, constructed and now operates, under long-term agreements, critical pipelines that support major projects for its customers. Examples include the construction, commissioning and operation of the Fortescue River Gas Pipeline (270km), the Wheatstone Ashburton West Pipeline (109km) and the Ashburton Onslow Gas Pipeline (24km). In addition, AGIG also owns Production License L9 (R1) containing the Tubridgi Gas Reservoir which it has commissioned as the largest gas storage facility in Western Australia.


AGIG’s team boasts a depth of experience, having operated and managed high-pressured gas pipelines not only in WA, but also throughout the east coast gas markets. DBP’s existing Perth-based Control Room has existing capacity and capability to effectively monitor additional transmission pipelines. Previously, it has managed the Eastern Gas Pipeline, Tasmania Gas Pipeline, Queensland Gas Pipeline, SW Queensland Gas Pipeline, Moomba to Adelaide Gas Pipeline and the Moomba to Port Bonython Condensate Pipeline.
