dampier to bunbury natural gas pipeline
a chinese company has made a bid for the dampier - bunbury gas pipeline .
the dampier to bunbury natural gas pipeline (dbngp) is one of the largest capacity natural gas pipelines in australia supplying natural gas to industrial, commercial and residential customers in perth and major regional centres along the pipeline route .
the owner of the dampier to bunbury natural gas pipeline has announced further expansion plans after receiving additional firm capacity requests from existing and prospective users of the pipeline .
dbp transmission (dbp), the owner and operator of the dampier to bunbury natural gas pipeline (dbngp) has announced practical completion of the stage 5b expansion project .
the owner of the dampier to bunbury natural gas pipeline anticipates construction work as part of the next stage of its $ 700 million expansion plans, will begin early next year .
extending almost 1, 600 km from the pilbara region to the southwest of western australia, the dampier to bunbury natural gas pipeline is an essential piece of gas infrastructure, supplying 90 per cent of the demand for gas in the region .
dbp is the owner and operator of the dampier to bunbury natural gas pipeline (dbngp), western australia’s most important piece of energy infrastructure. it has been in continuous operation since 1984 .
the dampier to bunbury natural gas pipeline (dbngp) is the longest natural gas pipeline in australia and runs entirely underground. it was commissioned in 1984 following three years of planning and construction. the dbngp is currently operated by dbngp (wa) transmission pty limited and trades as dbp. dbp is part of the australian gas infrastructure group .
“the dampier to bunbury pipeline is already a privately owned asset and a critical piece of infrastructure that is independently regulated, ” mr barnett said yesterday .
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. in 1985 the pipeline was extended to bunbury .
it comes as no surprise then that pipeline owner dampier bunbury pipeline (dbp) has expanded the pipeline’s capacity twice since it, acquired the pipeline in 2004 and has recently obtained necessary financing and equity commitments for an additional expansion .
duet, owner of the dampier to bunbury gas pipeline and other national energy assets, said yesterday hong kong billionaire li ka - shing’s cheung kong infrastructure had lobbed the takeover bid .
the owner of the dampier to bunbury natural gas pipeline has opted for a staged capacity expansion, fuelling speculation that planned expansion projects at alcoa' s wagerup alumina refinery and bhp billiton' s worsley alumina refinery will be deferred .
this report, published as bulletin 1153, provides the environmental protection authority' s (epa' s) advice to the minister for the environment on the strategic assessment of the concept by the gas pipeline sale steering committee (gpssc) to expand the existing dampier to bunbury natural gas pipeline (dbngp) corridor between kwinana and the kemerton industrial estate .
the dampier to bunbury natural gas pipeline (dbngp) is a transmission pipeline owned and operated by dampier bunbury pipeline (dbp). dbp is a part of the australian gas infrastructure group (agig). agig is owned by various consortia of hong kong - based entities listed on the hong kong stock exchange. the consortia include ck asset holdings ltd (cka), ck infrastructure holdings ltd (cki), power assets holdings ltd (pah) and ck hutchison holdings ltd (ckh )
on 31 december 2014, dbngp (wa) transmission pty ltd (dbp) submitted proposed revisions to the access arrangement for the dampier to bunbury natural gas pipeline (dbngp). the era published an issues paper on 20 april 2015, and received six submissions from interested parties in response .
around 500 bc, the chinese formed crude pipelines out of bamboo shoots to transport natural gas from natural seeps to boil sea water, separating the salt and making it palatable .
in april 1961, 140 years after the fredonia well, natural gas supply to the roma, queensland powerhouse commenced. this was the first time in australia that natural gas had been used to fuel electricity generation .
both natural gas and the pipeline play an important role in the state’s economy, providing the energy many major mining and resources customers need to power their operations. manufacturing and minerals processing industries are also underpinned by energy produced from natural gas .
this has built more than 45 years of experience in commercial large - scale natural gas production .
natural gas was formed in the earliest prehistory of our planet, during the jurassic period and earlier eras .
in fact, wa is the most energy and gas - dependent economy in australia with natural gas supplying more than half of wa’s primary energy needs .
find out how to become registered in the specific area of practice of oil and gas pipeline enginering .
so, after 3000 years of natural gas, people continue to use ingenuity and experience to tap this valuable resource to warm homes, cook meals and drive industry .
exploration and development to keep these pipelines full and meet the demand for natural gas continues, building on the decades of industry experience .
the first well drilled for producing natural gas was completed in fredonia, new york in 1821, 193 years ago .
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. the pipeline was also developed with the support of alcoa as its initial cornerstone customer .
at the same time, lng producers continue to commit to 20 - 25 year contracts to export wa gas to overseas customers .
following the recent pipeline rupture at apache energy’s varanus island facilities, cutting western australia’s gas supply by 30 per cent, there has been speculation about the need for a second major gas pipeline in the state .
gas contributes up to 50 per cent of western australia’s primary energy use and fuels up 60 per cent of the state’s electricity generation capacity. the dbngp is the only natural gas pipeline connecting the carnarvon basin on western australia’s north west shelf with perth and the surrounding region .
the dbngp was constructed by the state energy commission (secwa) to transport gas from the north west shelf gas fields near dampier to customers in the south - west of wa. construction began in 1982 and was completed in 1985 with the pipeline being extended to bunbury. the secwa as well as funding the construction of the pipeline also had the foundation contract for the supply of gas. the dbngp was also developed with the support of alcoa as its initial cornerstone customer. in 1998, as part of the privatisation of the secwa the dbngp was sold to epic energy .
the pipeline’s capacity has increased since 2005 by over 50% to meet gas demand in the south west and pilbara regions of western australia .
one terajoule is enough gas to supply an average home for about 50 years .
the pipeline is expected to be in service for at least the next 50 years .
prices are now two to three times the price of new gas in victoria. business and households face sharply rising gas and electricity prices .
after reviewing the wa’s future gas needs, the state government agreed to fund the building of a gas transmission pipeline that connected the gas fields in the state’s north with customers in the south - west. other methods of transporting gas from the north west gas fields such as road tanker, rail and ship were considered, but it was deemed that a pipeline offered the most efficient, economical, safe and environmentally acceptable means of transport .
established in 1984, the pipeline is responsible for supplying domestic gas from north west projects to homes and businesses in perth and the south west .
australian pipelines and gas association chief executive cheryl cartwright said foreign investment was not unusual in australia, including the pipeline industry .
dbp bought the pipeline from epic energy in october 2004, which had previously purchased the pipeline from the state government in 1998. since
however arguments against this take into account the production challenges western australia faces in regards to the supply of natural gas, as well as the ability for the dbngp system to continue expanding through the progressive addition of further looping and compression .
the pipeline’s proximity to homes, parks and playgrounds also meant a great deal of engineering analysis was required to ensure community safety .
the discovery of large offshore reserves of natural gas in the north of wa by west australian petroleum pty ltd and woodside petroleum in 1975 was the very beginning of the dbngp story .
gas today is the best source of trusted business information for the australian gas industry. gas today comprises an eponymous quarterly magazine, a news website, the annual book australia' s gas leaders, and a range of industry reference materials including an industry directory and maps .
shortly after that, australia started a major investment in bringing gas to city homes and industry .
“we will work with any infrastructure group or company that is interested in the future of australia’s gas and pipeline industries, ” ms cartwright said .
taking ownership, dbp has made expansion of the dbngp a key focus of the company, committing a total of $ 1. 8 billion to expanding the pipeline’s gas haulage capacity to meet western australia’s growing demand. this equates to 125 per cent of the regulated value of the pipeline as at 2005 .
the mainline, loop and lateral pipes are buried to provide stability in gas transportation and protection from damage .
in may 2005 the dbp board approved a $ 430 million expansion program – known as the stage 4 expansion – comprising eight new compressors and over 200 km of looping. looping involves installing additional pipeline parallel to the existing pipeline and then connecting the new pipeline back into the existing pipeline. this expansion increased the pipeline’s capacity by over 100 terajoules per day (tj / d) and was completed on time and within budget in february 2007 .
“these projects were all carried out in response to customer requirements. they were planned and executed to ensure that gas was available when it was needed for those customers’ projects and dbp remains ready and able to meet the future gas transmission needs of the state. ”
“as a result of these three projects, the firm full haul capacity has been increased by more than 300 terajoules per day and around 85 per cent of the dbngp between the north west shelf and bunbury is now duplicated, effectively creating a second pipeline to further improve reliability of supply. ”
rbc capital markets analyst paul johnston said the wa pipeline was duet’s most politically sensitive asset .
the dbngp was a covered pipeline and regulated by the western australian office of gas access regulation (offgar, now the economic regulatory authority (era) ) under the gas code. under the national gas access (western australia) regulations, the dbngp is classified as a ‘designated pipeline’. this means that under the ngl (ss. 109 and 111) the dbngp remains under full regulation and cannot be the subject of a light regulation determination .
however, cki has acquired majority stakes in electricity networks and gas distribution assets in four states .
jobs and investment are being lost interstate and overseas because of the state’s gas shortage and prices .
mr hohnen said “it could be said that the pipeline is the backbone of the booming western australia economy, the key to ongoing prosperity in this state. however we are functioning in a gas constrained environment and new supply is critical. ”
nominations are now open for the 2018 apga annual awards. the awards include the outstanding contribution to the australian pipeline industry award for individuals, the young…
at almost 1600 km, the pipeline is longer than the state of california (1, 240 km) .
natural gas has been recorded as a part of human history as early as 1000 bc when a goat herdsman noted a ‘burning spring’ on mount parnassus in ancient greece. i have seen similar burning seeps around kirkuk, iraq which locals assured me had been around as long as anyone could remember .
different aspects of the pipeline’s operations are regulated by the department of mines and petroleum, economic regulation authority and energy safety .
the tech drill looks at the science behind oil and gas operations and at how the petroleum industry uses innovation and cutting - edge technology to produce reliable energy .
the stage 5b expansion project has improved reliability and increased the pipeline’s firm full haul capacity by around 110 terajoules per day. construction commenced in early 2009 and predominantly involved looping, which is the installation of new pipe lengths parallel to the existing pipeline. stage 5b saw 440km of parallel pipe installed along the almost 1, 600km length of the dbngp. the project also required upgrade works on the pipeline’s compressor station facilities .

rick has worked in operations, project management and commercial areas of the oil and gas industry for more than 25 years .
dbp’s ceo stuart johnston said forecast total project expenditure to completion is estimated to not exceed $ 675m, as compared to the approved capital budget of $ 690m .
secwa operated the pipeline until its privatisation of sale in 1998. in 2004 it was purchased by dbp. during dbp’s ownership, $ 1. 7bn has been invested into the dbngp in meeting the energy needs of western australia, via separate expansion projects, stages 4, 5a and 5b. as a result of these projects the pipeline capacity was increased by 60% with the pipeline now being 83% duplicated or “looped” .
the premier has defended his proposed sale of 51 per cent of western power by using the example of the pipeline sale as a good result .
“the completion of the project is also of major significance to the state, with the extra gas transmission capacity, and enhanced reliability of services crucial in ensuring continued economic growth in wa. ”

the state energy commission (secwa) was responsible for the project and it commenced engineering design in 1979. at the time, the construction of the dbngp was the biggest infrastructure project wa had ever seen. as well as a lengthy design and feasibility process, the state government had to acquire rights to the land needed to house the new pipeline prior to construction. this land is now known as the dbngp corridor and remains state owned and managed today .
the stage 4 and 5 expansions will effectively duplicate approximately 90percent of the length of the dbngp. dbp says that this is a much faster and more cost effective approach to the delivery of new capacity than the construction of a second pipeline system, which it says would be heavily underutilised for many years – at high cost to users .
