Perth company wins Baltic Sea HDD contract

The scope of the contract include at least 110 km of subsea pipelines, a major shore crossing, risers, platform tie-ins and general system engineering.

Trenchless Technology will be employed for certain portions of the project, with horizontal directional drilling being used for the installation of the shore crossing.

Adam Czajko, Director of Subsea Engineering Associates (SEA), said “Our focus this year is to lock in the value generated during FEED by completing the design and going out to the market with tender packages for the main scopes.

“We expect significant interest from contractors and suppliers given the current state of the market. With tendered costs, the project should be in a strong position for Final Investment Decision during the second half of 2016.”

SEA recently opened an office in Gdansk, Poland which will play an important role in managing the Baltic Gas Project contract and other opportunities in the Baltic region.

AGL identifies 30 gas leaks using trenchless

Ahead of releasing the report, AGL conducted comprehensive leak detection surveys that covered thousands of gas wells and processing facility components. Using trenchless leak detection methods, the company was able to repair all identified leaks on the Camden Gas Project within the day. Col Duck, AGL’s Head of Gas Operation, said “The Camden Gas Project has been operating safely since 2001 with 96 operational wells. “The testing program uses the US Environmental Protection Agency’s ‘Method 21’ for leak detection, where the detector probe is placed at or on the component being tested. “This can find leaks that are otherwise undetectable if the probe is moved just a few centimetres away.” The final Leak Detection and Repair Report listed at least 30 leaks, none of which were classified as ‘significant’ according to US Environmental Protection Agency EPA standards. The Camden Gas Project is located in New South Wales and produces approximately 5 per cent of the state’s gas. For further information or to download the full report visit the AGL website.

Golden Gecko awarded to innovative microtunnel project

The Wheatstone microtunnel links a 225 km long offshore gas pipeline to the onshore processing facilities, protecting the coastal area adjacent to the Ashburton River Delta. Mines and Petroleum Minister Bill Marmion presented the Golden Gecko Award to Chevron Australia at an awards ceremony on Thursday 29 October. Department of Mines and Petroleum (DMP) Executive Director Environment Dr Phil Gorey said the project project stood out to the selection committee and was a very deserving recipient of the 2015 Golden Gecko Award. “The Wheatsone natural gas development is adjacent to the Ashburton River Delta, which supports important mangrove and estuarine habitats,” Dr Gorey said. “Chevron investigated five options for a shore crossing and chose the one with the lowest environmental impact, even though it was the most expensive choice. “Their commitment to environmental excellence was evident from the level of assessment and engagement undertaken during the project’s development. “Monitoring undertaken on the Ashburton River Delta demonstrated excellent environmental outcomes with no ground disturbance and an increase in the number of mature mangrove trees adjacent to the tunnel corridor. “Other excellent environmental initiatives included using biodegradable hydraulic oils, not using chemicals for the last 50 m of tunnelling, reusing all tunnel spoil, recycling almost all recyclable waste, and formally recognising individuals who improved environmental awareness of the project through an award program initiative. “This is the first time Chevron has successfully used microtunnel technology in the oil and gas industry and it is the longest pipe-jacked tunnel in the southern hemisphere.”

Hart on civil construction outlook

Mr Hart started his presentation by joking that Australian has changed its focus from mining to infrastructure; saying this was nowhere more evident than the department he worked in, which was formerly named ‘Mining & Infrastructure’, and now is titled ‘Infrastructure & Mining’. This global shift in focus was a key theme of his presentation, in which he said that while the construction industry may feel the crunch now in an interim change period, there is a strong forecast for growth in infrastructure in Australia by 2017. Australia’s economy is growing, but struggling to rise above the 2 per cent GDP per annum we are currently in. The fact we are still experiencing growth, Mr Hart says, is attributed to the resources sector – mining, oil, and gas – but it is not going to be a long term saviour for our economy and the federal and state government need to start shifting the focus of public investment. The bust of the mining industry Mr Hart predicts the ‘mining bust’ still has two to three years to run, saying “we have not hit rock bottom yet”. Because of the declining mining and minerals industries, which have primarily boomed in Queensland and Western Australia, it is not surprising the forecast for investment across the states of Australia show definite winners and losers over the next two to three years. Predictably, Queensland and Western Australia will be hit hardest for growth and investment, with New South Wales and Victoria in a much stronger position due to upcoming infrastructure projects in road and rail. Mr Hart gave advice to those involved providing infrastructure contracting to plan and prepare for what will be a tumultuous time for the industry over the next 3-5 years by looking state by state and by sector in planning future investments. He advised to assess the opportunities and risks involved, and to strike now and lock in low level costs on projects over a long period of time if the opportunities arise. For infrastructure providers, he recommended looking at the best time to deliver long term projects to avoid ‘busts and booms’ that give increasing cost risks along the way. “Booms come through and you get higher costs of delivering infrastructure,” he said. Looking globally “Globally, economic conditions are very volatile,” advises Mr Hart. “We have a slow moving global economy at the moment. First came the financial crisis, then the stimulus money followed after that. It’s improving gradually but not dramatically so.” For China growth is slowing. However, while its growth rate is slowing, the amount they are adding to their economy each year isn’t, due to the size China grows per annum. This seems positive in representing future economic opportunities for Australia, whose trade bolsters our economy. However, the problem for Australia is that the Chinese economy is shifting; it’s no longer being driven by infrastructure investment that demands the minerals and raw materials that Australia has been supplying. Investment in infrastructure According to Mr Hart, Australia has just passed its peak in oil and gas investment. The former $40 billion dollar investment in oil and gas is falling, and Australia needs new drivers for growth. Public investment, he says, is vital to this. Public investment in infrastructure has been falling since 2010. For the past two years, the country has also had declining investment in mining, in addition to the declining investment in infrastructure. “No wonder you’ve been feeling pain, two big drivers working against you,” he said – a sentiment that would reign true for many in the civil construction industry. However, Mr Hart states that public investment is picking up from here, and that NSW is going to surge – especially in road and rail, key industries where trenchless relocation of services are required. Things still look tough for the infrastructure sectors until this shift in focus happens. “Over the next few years we will feel the squeeze from the mining investment downturn,” said Mr Hart. “After this year we expect to see housing stabilising – most states reaching a balance in the housing market. Only Sydney will still be over supplied in housing. “Engineering construction will be picking up later this decade. Currently we’re in a downturn in engineering construction that’s being driven by the mining bust, and we’ve also reached a trough in publicly funded works. However, things should start picking up again.” Mr Hart said the major question on his mind was how to package the predicted investment in infrastructure so that it effectively sustains the construction industry, not just the bigger players who can bid for billion dollar investment work. How do we involve the whole industry? What industries will see investment? Water: The key area Mr Hart pegged overdue for water infrastructure investment was in regional areas, and said we should start to see funding come through for this over the next few years. The over-investment in desalination plants and dam infrastructure would see somewhat of a general downturn for water investment. Electricity: Australia still needs to invest a significant amount of infrastructure to meet its renewable energy target. This will result in building more wind farms and potentially a solar tank to meet this energy target. Telecoms: The National Broadband Network continues to drive civil construction work in this sector. Oil and gas: Mr Hart says the bust in this industry is due to last another few years yet, but advises the construction industry to not pin any hopes on a mining recovery. Ending his presentation, Mr Hart emphasised the need for far-thinking vision, giving the Sydney Harbour Bridge as the example par excellent. Even though it was built in 1930, when very few cars were on the road, they gave the bridge eight lanes. They foresaw the population’s the future needs. While the civil construction industry will feel the downturn of the mining and resources industry, as Australia turns its focus to investment in infrastructure,

GLNG production starts on Curtis Island

The liquefied natural gas (LNG) is being transported by a 4.3 km of tunnel installed under ‘The Narrows’, connecting the Curtis Island plant to the mainland near Gladstone. The tunnel was constructed using a 4.1 m diameter Herrenknecht tunnel boring machine. The production of LNG marks a significant milestone for the project, with first cargo expected to be transported to Asian markets in the coming weeks. Santos Managing Director and Chief Executive Officer David Knox said “We said we’d produce first LNG around the end of the third quarter, and that’s exactly what we’ve done. Our upstream facilities are fully operational and performing well, we’re producing LNG on Curtis Island, and we’re now looking forward to safely delivering our first LNG cargo in the coming weeks.” The next phase for the project is to prepare Train 2 to be commissioned for start-up by the end of 2015. So far this stage of construction is progressing on time and on budget. Read more about the GLNG project on Trenchless Australasia or visit the Santos website.

Full scope closes 24 September 2015.

Proposed Arrow Bowen Pipeline length shortened

New South Wales-based drilling contractor Daley Directional Drilling recently took delivery of a Toro DD4045 directional drill. Established in 1999 to provide a trenchless utility laying solution for the construction and civil industries within the state, Daley Company Director Michael Daley explained that the family-operated company was previously using Astec Directional Drills. As he was content with the machine’s power and performance, when it came time to upgrade the old model, Mr Daley wanted to keep using the same machine. However, with Astec Underground acquired by the Toro Company (Toro Australia’s parent company) in 2012, so Daley Directional Drilling subsequently bought their new machine from Toro. “The DD4045 is being used for all types of directional drilling work in different applications involving water, power, gas and communication,” said Mr Daley. “We really like the power the DD4045 offers, especially considering its size. Having the cabin is good too as it offers more comfort for the operator. “Another good feature of the machine is the flexibility to choose either single or dual joystick operation while drilling. Overall, we are very happy with the DD4045 and the service and back up received so far from Toro.” Toro rig integral for Integra Another user of Toro directional drills is Queensland-based Integra Contracting. Also formed in 1999, the company sought to meet the increasing demand for quality construction and maintenance resources in the communications and utility distribution sectors. Integra Contracting Managing Director Ole Ebbesen described how the company came to use a Toro DD2024: “We had only recently bought a second hand Astec directional drill. Greg Ivanovic from Toro came out to show us how to operate the machine and mentioned that if and when we were ready to upgrade, we could trade-in the Astec machine,” he said. “When we were ready, Toro also let us trial a DD2024 for three weeks. They are the only company who will take trade-ins and they also gave us a good deal on the new machine.” The DD2024 is currently on the job in the Brisbane Botanical Gardens, laying fibre optic cable and electrical conduit. Mr Ebbesen finds the machine very powerful for its size and considers the narrow footprint of the DD2024 one of its major advantages. The machine measures only 132 cm wide, 526 cm long and 188 cm high, making it easily transportable and capable of drilling in tight spaces.

HDD upstream

Over the past decade horizontal directional drilling (HDD) has played a prominent role in Australia’s oil and gas sector, with many blue chip resource projects utilising HDD for construction or installation of upstream assets. However, the use of HDD in the oil and gas sector can differ significantly between utility and civil infrastructure counterparts.

One individual who has worked on both upstream HDD projects and utility projects is Charles Stockton of Stockton Drilling Services. Specialising in HDD engineering and project management, Mr Stockton’s company has provided services such as QC inspection, risk management, feasibility studies and HDD supervision for Chevron’s Gorgon Project, ExxonMobil’s Longford Gas Conditioning Project, BG Group’s QCLNG project and Arrow Energy’s Curtis Island LNG and Bowen Pipeline Projects.

Upstream vs. utility

Working for both clients and contractors alike, Mr Stockton regularly engages with both sides of the HDD upstream industry. Comparing HDD’s use between the oil and gas and utilities sectors, Mr Stockton told Trenchless Australasia that oil and gas projects tend to be more complex in size, scale and environment.

“For example, the pipeline for the Gorgon shore approach was 86 cm in diameter with a wall thickness of 42.5 mm and the complete string weighing over 700 tonnes,” he said.

“Lifting and creating the overbend can be both complex and challenging – even more so if the pipeline has to be pulled from an offshore environment.”

As the pipeline diameter increases, so do the buoyancy forces created by the pipe as it displaces the drilling fluid during insertion, continued Mr Stockton.

“This adds an additional process of water ballasting to the pullback, that must be well planned and coordinated.”

The nature of steel pipelines – a favoured asset material in the oil and gas sector – means it is also essential for the pilot hole to be accurately drilled and the bore well-conditioned, said Mr Stockton.

“A 106 cm pipeline will require a radius of approximately 1,000 times the pipe diameter to be drilled, whereas a polyethylene pipe may be closer to 35 times the pipe diameter.

“As the radius becomes larger, the profile effectively straightens and thereby reduces the acceptable deviation of the drill bit. This makes accurate surveying and experienced drillers essential for meeting oil and
gas specifications.”

Taking a risk or paying the price

Another key point of difference for HDD in oil and gas projects can be found in the design process, which is often driven by a risk-based approach compared to a utility project’s focus on price, said Mr Stockton.

“Oil and gas projects proceed through a number of development phases that allow all risks to be fully evaluated both before and after tender. At each step of the process, a diverse group of experts will review and challenge the design to ensure all risks, including package interfaces, are correctly identified and managed. This ensures the tender evaluation process is driven by project outcomes and not price.”

By contrast, a recent utility project had as much as 90 per cent of the tender evaluation criteria fixated on price – something that would not normally be seen on a major oil and gas project, said Mr Stockton.

“Utility owners must start to realise that technical capability, quality, safety and environment are far more important than 10 per cent of the bid. For HDD to confirm its position as a reliable, safe and controlled process, more value and scrutiny should be placed on the engineering, design and contractor performance.”

To help cement HDD’s position, Mr Stockton has developed an HDD QC package in response to industry needs.

“Although HDD is often the most technical and challenging part of installing a pipeline, there are no inspection and quality controls,” said Mr Stockton. “The process is often left solely to the contractor or Client Superintendent who has limited HDD experience.”

By incorporating risk management into all phases of a project, the key risks will drive the project’s ongoing design and construction methodology, concluded Mr Stockton.

“In the feasibility stage, for example, the key project risks are identified and are the primary drivers for determining project feasibility and further studies. As the projects progress through further stages, the risk assessment – which is a live document – becomes more refined and detailed.”

New McConnell Dowell CEO named

Mr Cummins takes over from David Robinson who will be retiring in October this year. Mr Robinson will remain available to the company in a consulting role. Kobus Verster, CEO of McConnell Dowell’s South African parent company Aveng, said the appointment follows a comprehensive executive search that considered both internal and external candidates. “I am confident that Scott will lead McConnell Dowell in sustaining its track record in its anchor market, Australia, while helping us realise the full potential of its international operations,” said Mr Verster. Mr Cummins previously worked in project management and leadership roles for McDermott International, working across the company’s marine, production, construction engineering, fabrication, business development and regional operations. Kobus Verster also thanked outgoing CEO David Robinson for his 15-year tenure as CEO. “Mr Robinson has overseen periods of considerable growth and change within McConnell Dowell and has led the company through challenging times and market transitions,” said Mr Verster.

$A2.9 million trenchless pipeline set for June completion

First announced in February 2015, the $A2.9 million project extends from Geelong to Torquay via Armstrong Creek.

Directional drilling was utilised throughout the majority of the project to protect existing services within road reserves and minimise impacts to the local flora and fauna.

Once complete, the pipeline will significantly eliminate the risk of supply interruptions during peak periods and help meet new connection growth in the area.

AusNet Services Gas Network Manager Elias Raffoul said the new pipeline will support the fast-growing areas south of Geelong and Torquay.

“With thousands of new homes being built in Armstrong Creek, Torquay and Jan Juc, there has been a strong up-take of gas for general heating, cooking and hot water systems,” said Mr Raffoul.

“This new 11 km pipeline will help secure the supply of gas to the residents during peak winter periods and provide capacity for up to an expected 5,000 additional homes in Torquay and Jan Juc.”

In additional to the new pipeline, AusNet Services is also preparing to extend its reticulated natural gas network to Bannockburn and Winchelsea as part of the State Government’s gas extension program

CH2M Hill becomes CH2M

CH2M was established in Oregon, United States, nearly 70 years ago by three engineers and their professor to solve local water challenges. The company’s brand name is a nod to these founders “” Cornell, Howland, Hayes and Merryfield “” literally “CH2M”. “Through the years, CH2M has evolved from a regional engineering and consulting firm associated with first-of-a-kind projects to a global leader associated with some of the largest, best-known infrastructure programs for public and private clients,” said CH2M Chairman and Chief Executive Jacqueline Hinman. Hinman said that the time was right for CH2M to make this move. “The last time we rebranded the company was in the 1990s,” she continued. “Since that time, CH2M has grown from 5,000 to 25,000 employees, working in more than 50 countries and with annual revenues of almost $US6 billion.”

Advertising online is a great way to cost-effectively test if a particular market is a good fit for your product or service.

Business marketing: the value of advertising online

Remember when you first developed your company website? Just like email, your website has revolutionised the way you sell your company and its products and services to the world. Search engine optimisation can only take you so far and to reach highly engaged individuals searching for vital information, it’s important for your company to be advertising on the websites that matter in your industry. But what are the benefits of advertising online? Timely promotion and flexibility The immediacy of online advertising ensures that products can be introduced to the market very quickly. There is also design flexibility so web adverts can be eye catching and alternate between different banners. This also allows you to rapidly test different messages in short periods of time to see what is most effective. Tracking capabilities The best thing about online advertising is its ability to track the performance of your campaigns. Through using online advertising your company has the ability to track every single click and every single user to see if they end up becoming customers. It is worthwhile downloading Google Analytics – it’s free and will allow you to track the pathway visitors are taking to your site and their movements within your site. Are your online ads generating traffic? Which sites are referring visitors to your site? Google Analytics can help give you the answers. Cost effective Banner advertisements offer great value due to low production costs. If you have advertised before then you know that just one advertisement may not have the phones ringing hot, so think about what your aims are and perhaps look at booking a series of advertisements and combining this with strategically placed editorial content. Most websites have packages available and these should offer the best value and exposure over varied periods of time. High volume The sheer volume of visitors to industry websites means that by advertising you are highly visible to many new readers and potential leads. Most industry websites offer site visitors a free subscription to their e-newsletter which is often sent weekly or fortnightly to thousands of subscribers. By signing up, these e-newsletters subscribers have demonstrated a high-level of engagement, and so advertising in e-newsletters is highly coveted and tends to be a more exclusive and expensive online advertising option. Test the market Advertising online is a great way to cost-effectively test if a particular market is a good fit for your product or service. If you have a well-designed online advertisement and you are advertising on the right industry website then you should get some decent traffic – and those all-important leads. Entire industry coverage The best way to get entire industry coverage is to take out advertising in print, online, and have an event presence. If your company can only initially afford one or two of these promotional opportunities, the results will speak for themselves and you will have a clear case to argue for an increase in next year’s marketing budget. TIP: If you are taking out multiple advertisements then you should be rewarded with a discount, but also ask about securing some editorial coverage to maximise your impact. Highly targeted Visitors to industry websites are usually looking for information to help them do their job better, so they are highly engaged. Every person who views your advertisement is a prospective customer and you need to convey instantly that your product or service is what they need. Just online, all online? So, you’re a convert – you have decided your company needs to start advertising online. But what about your magazine advertising and exhibiting at prominent industry trade events? The good news is that online advertising is the perfect complement to your other marketing efforts. Online advertising is rarely enough on its own but by combining it with print and event participation in a strategically planned campaign, your company will receive maximum industry coverage and make a significant impact. Writing your advertisement Perhaps you have tried online advertising and you didn’t get the great results you expected. Be warned: the advertisement you run in your print campaign will not be suitable for online. If you use the same sort of advertisement you are unlikely to get the traffic you deserve. For best results you should make an offer and be instructive (find out, how to, click here). Through the use of ‘active words’ (for example: order, reduce, choose, use, apply), you can entice people to click your advertisement and learn more about your offer/product/company.

Arrow route: Arrow Energy's proposed Bowen Gas Pipeline will run throughout Central Queensland.

Stockton studies HDD for Arrow Energy’s Bowen Gas Pipeline

This project emerged from SA Water’s desire to trial trenchless technology using established local contractors. Originally, two options were tabled: slip lining and swagelining, with the later chosen as the preferred option. CLM Trenchless offer swagelining as a rehabilitation process for the renewal of pressure and non pressure pipelines in water, sewer and industrial applications. The process is ideally suited where techniques such as open trench or pipebursting are not suitable. The swagelining system uses polyethylene (PE) pipe, which has an outside diameter slightly larger than the pipe to be rehabilitated. After sections of PE pipe are butt fused together to form a continuous string, the PE pipe is pulled through a reducing dye to temporarily reduce diameter. This allows the PE pipe to be easily pulled through the host pipe. After the PE pipe is inserted, the pulling force is removed, allowing the PE pipe to return naturally toward its original diameter until it presses closely against the wall of the host pipe. The new tight fitting pipe results in a flow capacity close to the original pipeline design. This technology is suitable for applications ranging in diameter from 300 mm up to 1,000 mm, and a wide range of fittings are available from various manufacturers. CLM Trenchless is a licensee to Advantica and currently is the only contractor performing swagelining in Australia having also completed a project in Hobart and in Sydney recently for Sydney Water. The South Parklands project involved the rehabilitation of 1 km of DN600 cast iron watermain in an environmentally sensitive location (open parkland adjacent to the CBD) using the technique of swagelining in four 250 m sections. The PE used for this project was PN12.5 HDPE 630 mm with a 47 mm wall thickness. The swagelining process involved setting up five 12 m long launch and receipt pits, butt welding 20 m lengths of PE and positioning of the swagelining rig and hydraulic pulling equipment (Tracto Technik 800G). Installation took two weeks to complete with each run taking approximately 4 hours at a consistent pulling load of 60 tonnes. The equipment required for this project was manufactured by CLM Trenchless. SA Water has encouraged the investigation of new rehabilitation techniques. In particular, John Ringham, Chief Operating Officer for SA Water, has wanted to see Trenchless Technology embraced as part of their renewals program given his extensive experience in the UK with large scale rehabilitation programs of water networks. Swagelining has been around for some time but with recent developments in pipe manufacture and specification, it has now opened up the range of application for this technology. CLM Trenchless General Manager Trevor Groeneveld said “With the experience we have gained from this project, we are now quite excited about the potential growth in large bore pipeline rehabilitation.”

Chevron Gorgon Project expansion to use HDD

Approved 3 March 2015, the project – known as the Gorgon Gas Development Fourth Train Expansion Proposal – will seek to expand the liquefied natural gas (LNG) production capacity on Barrow Island, Western Australia by 33 per cent, from 15 to 20 million tonnes per annum. According to Environmental Protection Authority (EPA) Chairman Dr Paul Vogel, the proposal’s horizontal directional drilling (HDD) component had been subjected to a Public Environmental Review, the Authority’s highest level of environmental impact assessment. “The EPA carefully assessed the potential impacts to marine environmental quality, marine fauna, air quality and benthic communities and habitat and found that the proposal could be managed to meet the EPA’s objectives subject to the conditions in the existing Ministerial Statements issued for the original project.” These conditions included management plans for the HDD activities, alongside marine environmental quality, gas pipeline installation, marine fauna, air quality and greenhouse gas abatement, said Dr Vogel. The EPA’s report to the Minister for Environment is now open for a two-week public appeal period, closing 17 March 2015. Appeals are administered independently by the Appeals Convenor and can be made here. The Minister for Environment will make the final decision on the project’s approval.

$A2.9 million gas pipeline to boost Torquay supply

According to AusNet Services, the 11 km pipeline will run from Geelong to Torquay in Western Victoria, reducing the risk of supply interruptions during peak periods and catering for new residential and commercial growth. Scheduled for completion mid-2015, horizontal directional drilling (HDD) will be utilised throughout the majority of the project. The trenchless technique was selected as it would protect existing services within road reserves and minimise impacts to the local flora and fauna, said an AusNet Services spokesperson. In planning the project, AusNet Services undertook a Biodiversity Assessment and a complex Cultural Heritage Management Plan, with both reports submitted to local councils. Construction work for the project began earlier in February and is scheduled to take place predominantly along the alignment of Horseshoe Bend Road in Mount Duneed. AusNet Services General Manager of Asset Management Alistair Parker said the new pipeline will future-proof the gas network in the burgeoning areas south of Geelong and Torquay. “With thousands of new homes being built in Armstrong Creek, Torquay and Jan Juc, there has been a strong up-take of gas for general heating, cooking and hot water systems,” he said. “The new 11 km pipeline will help secure the supply of gas to the residents during peak winter periods and provide capacity for up to an expected 5,000 additional homes in Torquay and Jan Juc.”

Trenchless upgrade for Bowral gas network

Gold-lining involves inserting modern, high-density nylon piping into existing gas mains – such as old cast iron mains and old high-density polyurethane gas mains.

“Rehabilitation of the Bowral network will minimise the likelihood of gas leaks or a loss of gas which sometimes happens when these old cast-iron pipes become rusted or the old HDPE gas mains start to crack,” said Jemena General Manager for Gas Peter Bowden.

The Bowral rehabilitation project is one of many that are part of Jemena’s $A810 million investment over a five-year period to upgrade and extend the Jemena Gas Network.

Since 1987, Jemena has rehabilitated almost 6,000 km of gas mains, which represents almost a quarter of the 25,000 km-long Jemena Gas Network in New South Wales. This network distributes natural gas to over 1.1 million homes and businesses throughout the state.

HDD goes under live gas facilities

The development of a new gas conditioning plant to the east of Longford Gas Plant’s existing processing facility required control cables and high voltage cables to be rerouted in and around the existing live crude oil and gas plants.

Stockton developed a strategy where the scope would be split into two distinct parts. The initial scope, known as the Northern Alignment, would be packaged as seven drills to install conduits from manhole to manhole. These would be
125 mm HDPE ducts and range in length from 150-270 m. These works could then be undertaken by a small rig operator outside the main plant areas using the minimum required footprint.

The second scope, known as the Southern Alignment, would be conducted from within the plant boundary with a drilled length of just over 1,000 m. The alignment would pass beneath existing infrastructure for Gas Plants 1, 2 and 3 and the Crude Stabilisation Plant. In total, sixteen conduits for high-voltage and earth cables would need to be fabricated and installed.

Developing a HDD solution

Stockton, along with Wood Group PSN, developed the horizontal directional drilling (HDD) designs whilst Golders was engaged to carry out the geotechnical investigation. The design process commenced in late February and tenders were released just two months later. Contractors were then invited to bid on one or both scopes; contracts were awarded in July, with BTB Australia commencing the Northern Alignment in September 2012 and Geotech Drilling the Southern Alignment in November 2012.

A number of technical decisions were made by Stockton to optimise the number and size of bores required for the Southern Alignment. It was determined that a dedicated 280 mm diameter mud return line would be drilled first. This would remove the requirement for road tankers within the plant and allow guidance cables to be installed below ground for steering the remaining bores. Together, these measures would significantly reduce the impact on normal plant operations. The mud return line would also be a spare should any subsequent conduit be damaged during installation.

After considering whether the bores should be cased or uncased, it was determined that sixteen 160 mm diameter conduits should be installed uncased, grouped in four bundles of four. The conduits would be progressively ballasted with water during installation to minimise installation loads, to ensure the bundles remained in their crucial trefoil configuration.

Managing the site

As part of the Northern Alignment, two of the parallel bores would pass beneath a service corridor containing numerous existing underground services, including the main incoming gas pipelines. The congested nature of the processing plant required ground penetrating radar surveys to be conducted at all entry and exit points to check for unmarked services. All services detected were then exposed and confirmed by potholing. By adopting HDD, no exposed trenches were dug in public spaces, including car parks, and it ensured separation was achieved to all known and potentially unknown services.

For the Southern Alignment, HDD was the obvious solution as it provided a quicker, cheaper, safer and more manageable option. An open trench through the existing infrastructure would introduce many ignition sources along the full alignment of the works.

A technological first for Australia

Stockton utilised its state of the art inertia gyro to progressively map the installed pipelines. It is thought to be the first time this type of gyro has been used in Australia. The Stockton-conducted gyro surveys of each installed bundle provided third party verification of the exact position of each conduit. By conducting an independent gyro survey, the pipeline owner can mitigate potential future risk by confirming the exact position and bend radius of the installed pipe.

Environmental impact

One of the project’s highest risks identified was the potential impact from frac-out. Having mud returns come to surface within the pipe racks, service corridors and infrastructure of the existing plant would have caused major safety and operational concerns. This risk had to be actively managed during design and construction to be reduced to as low as reasonably practicable. Hydraulic fracture modelling was undertaken for numerous bore profiles. This allowed for the optimum depth to be determined along with the preferred bottom hole assembly (BHA) configuration, pump rates and mud rheology.

During construction a pressure sub was included in the BHA to monitor annular pressure gradients and a qualified mud engineer was on both shifts to maintain the fluid design parameters. These safeguards and others, including surface entry casing, ensured all five bores were drilled without any incidents of frac-out.

Success of the project to date

By May 2013, all twelve bores housing the 24 conduits were successfully installed without incident and with minimal disruption to Longford operations. The Longford Gas Plant, who had previously never employed HDD, has since seen the benefits of trenchless operations and as a result BTB Australia will be returning later this year to install two further drills for raw water and stormwater pipeline upgrades. Stockton supervisors will again be employed on-site to provide the construction oversight.
