Coffey Testing provided concrete testing and aggregate testing alongside Boral for Bechtel which included the testing of over 478,000 m3 of concrete and 940,000 ton of concrete aggregate.
- Client: Bechtel
- Project: Wheatstone LNG
- Duration: 5 years
- Location: Onslow, Western Australia
Coffey Testing delivered construction materials testing on the multi-billion dollar Wheatstone LNG Project, which is one of Australia’s largest resource projects and was one of the 6 major LNG projects under construction throughout the period from 2011 – 2016.
The gas field for Wheatstone is located approximately two hundred and twenty-five kilometres off Onslow situated on the northwest coast of Western Australia. The plant itself is approximately twelve kilometres west of Onslow. The gas reserves are sufficient to supply a two train LNG plant. In order to process the natural gas, Chevron constructed the LNG plant which will eventually have the capacity to produce up to 8.9 million tons per annum of LNG for domestic and international supply.
The Project was hugely environmentally sensitive and successful in the management of the environmental considerations and requirements including the repatriation of many fauna and flora species.
The Project included significant construction elements including the offshore production facilities, onshore gas processing, liquefied natural gas facilities, an export pipeline to the shore and a first hub concept.
Coffey Testing provided concrete testing and aggregate testing alongside Boral for Bechtel which included the testing of over 478,000 m3 of concrete and 940,000 ton of concrete aggregate.
We conducted 58,695 concrete cylinders, 11,032 concrete slump tests, 2,698 tests on concrete aggregate as well as associated testing which in all totalled 78,989 NATA endorsed materials testing reports.
Our laboratory was state of the art and catered to the production demands of 25,500 m3 of concrete per day at peak. A construction project of this nature, considering the potential dangers of LNG plants that are processing highly flammable materials requires the construction materials testing to be conducted with high diligence to reduce risk of weakening structural integrity.
The Project brought together local industries and indigenous and community groups and is one Coffey Testing is very proud to have been associated with.
Of the 6 major LNG projects constructed concurrently, Coffey Testing also carried out construction materials testing and quality assurance activities on Upstream and Downstream major projects of the APLNG Project, Ichthy’s Inpex Project and the Gorgon Gas Project on Barrow Island.
Some of these large-scale remote projects we worked on had, at peak, laboratories with over 40 geo-technicians conducting materials testing on aggregate, concrete and soils as well as associated quality assurance activities. Coffey also provided geotechnical engineering, environmental consultancy and speciality testing to many of these projects displaying our ability to deliver cradle to the grave services.
