Alshor Plus, Rapidshor and Minima used on numerous LNG and CSG Projects
Building on over 60 years of success in the Australian construction industry, in recent times RMD Australia has also won a raft of major contracts to supply materials and provide specialist services for a number of Australia’s largest LNG and CSG projects, including, most recently: the massive Ichthys LNG project in Darwin and the Wheatstone LNG project located 200km north of Onslow, off Western Australia’s Pilbara coast.
Prior to these recent contract wins, RMD Australia supplied equipment and engineering services to two other huge LNG projects: the Pluto LNG and Gorgon LNG projects, both in the North West of Western Australia. In addition to its success with LNG projects, in the past few years, RMD Australia has also been awarded contracts to supply equipment and accessories to most of the major CSG projects in Australia, including: Australia Pacific LNG; Gladstone LNG; Queensland Curtis LNG and PNGLNG in Papua New Guinea.
Of all the projects, the Australia Pacific LNG (APLNG) project turned out to be the most noteworthy of the CSG projects for RMD Australia, as a result of the high and sustained level of equipment supply achieved. RMD’s involvement in LNG and CSG projects of this magnitude and significance is testament to the company’s determination to be a main supporter of Australia’s infrastructure through continued product development and project expertise, in partnership with some of the world’s largest contractors.
Ichthys LNG Project
The Ichthys LNG plant at Blaydin Point on Middle Arm Peninsula in Darwin Harbour is expected to produce some 8.4 million tonnes of LNG, together with an additional 1.6 million tonnes of LPGs (propane and butane) per annum and around 15,000 barrels of condensate per day at peak.
RMD Australia’s Alshor Plus shoring system was used by Leighton Contractors to support 8 turbine slabs over the two LNG trains that were constructed. Each train consisted of 2 x 12m high slabs and 2 x 7m high slabs. The 12m slabs are approximately 50m long and 13m wide and the 7m slabs are approximately 8m long and 5m wide, so they are extremely large structures.
Leighton’s have also used RMD’s Minima formwork panel system to produce 800 pedestals spread across five flare pads. Although they are of various sizes, Minima was easily able to form them.
Wheatstone LNG Project
The Chevron-operated Wheatstone Project is one of Australia’s largest resource projects. Located at Ashburton North, 12km west of Onslow in Western Australia, the Wheatstone Project is a joint venture between Chevron, Apache Corporation, KUFPEC, Kyushu together with PE Wheatstone Pty Ltd.
The initial phase of the project consists of the construction of two liquefied natural gas (LNG) trains with a combined capacity of 8.9 million tonnes per annum along with a domestic gas plant. RMD Australia is supplying its Minima formwork system and innovative Alshor Plus shoring system to Laing O’Rourke whose scope of work consists of engineering, design, procurement and construction activities for the foundations and structures to support the Wheatstone’s two LNG trains and the utilities plant for the domestic gas plant.

Pluto LNG Project
This Woodside LNG project, processes gas from the Pluto and Xena gas fields, located in the Carnarvon Basin about 190km North-West of Karratha, in Western Australia. Pluto is a single train LNG project located adjacent to Woodside’s already existing North West Shelf five train LNG facilities.
RMD Australia was involved in all aspects of the formwork including footings, simple wall forms, detailed wall forms, single height pours to 8.6m, suspended concrete bridge road crossings, ring beam formwork, temporary works to suspend cast in bolt templates and jetty construction.
The main equipment supplied to numerous clients on this project includes the Rapidshor shoring system, Super Slim Soldiers, Megashor heavy-duty shoring system and the Minima panel formwork system, which have all performed exceptionally well.
RMD Australia’s diverse range of equipment, responsive customer service and effective engineering solutions placed them at the forefront as the main supplier of formwork equipment on the Pluto LNG project.
Gorgon LNG Project
RMD Australia formwork and shoring solutions were used to support the construction of the Gorgon LNG processing plant, which delivers 15.6 million tonnes of LNG per year. It has a three train processing plant located on Barrow Island, a domestic natural gas plant and a carbon sequestration project off the coast of Western Australia.
Formwork solutions supplied by RMD Australia include the Super Slim Soldier wall formwork system, the Minima formwork panel system and the Megashor heavy duty shoring system.
The Gorgon Project is one of the world’s largest natural gas projects and the largest ‘single resource’ natural gas project in Australian history.
As a result of RMD’s supportive sales force, highly capable engineering team and an extensive range of innovative products, RMD Australia has also been successful in winning supply contracts for a number of major CSG projects, including:
APLNG (Australia Pacific LNG)
The RMD Minima panel system was selected by Bechtel to form all of the concrete structures, footings and sumps for the gas plant at APLNG. Over 5,000 panels were supplied to complete these works and they remained on site for two years. Conventional formwork consisting of ply, LVL and bar tie was supplied to form the 1,000’s of pedestals that sit on these foundations.
The Rapidshor shoring system was selected to temporarily support the formwork and compressor slabs, which were 90m x 40m x 1.5m thick and 7.5m off the ground.
RMD Australia also supplied the compressor slab columns which were 1.1m x 1.1m x 7.5m high utilising Super Slim yokes and Alform Beam, complicated by the number of cast in items that needed to be fitted to the forms.
GLNG (Gladstone LNG)
John Holland was awarded contracts to construct the Materials Offloading Facilities (MOF) for all three of the CSG projects being constructed on Curtis Island.
The main works RMD was involved with on the GLNG MOF are the dolphins for the barge ramp, the barge ramp abutments and a capping beam on driven sheet piles, which is in total approximately 260m of 2m x 1m profile beam.
QCLNG (Queensland Curtis LNG)
Queensland Curtis LNG is one of Australia’s largest capital infrastructure projects, involving US$20.4 billion of investment from 2010-14. The project has drawn on QGC’s extensive natural gas expertise and BG Group’s international experience in LNG, at a time of rising demand for cleaner, more efficient energy.
RMD supplied components for erecting conventional formwork, such as Super Slim Soldiers and Alform Beam. The benefit of this type of formwork is its added strength and that it can be made to larger sizes than panel systems. Also the highly innovative Alshor Plus shoring system was used to support the compressor slabs.
PNGLNG (Papua New Guinea LNG)
The PNGLNG Project is a 6.9 million tonne per annum integrated LNG project operated by ExxonMobil PNG Limited.
For this project RMD supplied Reflex circular formwork for forming the LNG tank bases in addition to equipment to complete the LNG jetty formwork for BAM/Clough, which consisted of Megashor heavy-duty shoring, Super Slim Soldiers and Bar Tie.
