Alshor Plus and Minima used on Wheatstone LNG Project
The Chevron-operated Wheatstone LNG 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 Australian subsidiaries Chevron, Apache Corporation, Kuwait Foreign Petroleum Exploration Company (KUFPEC), Shell and Kyushu Electric Power Company (Kyushu) together with PE Wheatstone Pty Ltd (part owned by TEPCO).
The initial phase of the project consists of two liquefied natural gas (LNG) trains with a combined capacity of 8.9 million tonnes per annum as well as a domestic gas plant.
Laing O’Rourke is RMD Australia’s client on this project
RMD Australia is supplying formwork and shoring systems to Laing O’Rourke whose scope of work consists of engineering, design, procurement and construction for foundations and structures to support the project’s two LNG trains and the utilities plant for the domestic gas plant.
RMD Minima and Alshor Plus are the main products utilized
With an initial order to supply 300t of RMD’s Alshor Plus shoring system and 4,000m2 of Minima panel formwork to Laing O’Rourke in August 2013, Wheatstone further reflects RMD Australia’s success at winning large resource projects across the country.
More specifically, RMD Perth supplied Minima formwork panels to form crane bases and the compressor foundation slabs. Large columns were then formed at 1.1m2 and 1.5m2 and 8m high using conventional formwork made from RMD’s Super Slim Soldiers, Alform Beam and ply.
The Alshor Plus shoring system was installed with RMD’s Albeam primary bearers and Alform Beam secondary bearers to support the two slab pours.
Immense amount of equipment and drawings required
One of the main challenges was procuring the large amount of equipment required for this project in a short time frame and also keeping up with the ever changing designs from the client. Also a huge amount of detail was required in the drawings and RMD have prepared well over 1,000 drawings for this project, which is still ongoing.
This project has had numerous large and small footings, pedestals, plinths, sumps and columns for which RMD Perth supplied a combination of the Minima panel system and conventional formwork made from Super Slims and Alform Beam.
Developed a new product for the customer
RMD developed a new column yoke to assist the client in the speedy erection of forms for the plethora of columns required on the site. This work is ongoing and should run well into 2016.
