Chevron: Wheatsone LNG construction at half way point

The Chevron-operated Wheatstone LNG project in Australia is about 49 percent complete and remains on track for first gas in late 2016.

The Wheatstone project includes two LNG trains with a combined capacity of 8.9 mtpa plus a 200 terajoule per day domestic gas plant, located 12 kilometres west of Onslow on the Pilbara coast of Western Australia.

Fabrication of Train 1 modules at the LNG project continues, with the first module expected to be delivered to Ashburton North in late 2014, Chevron said in a project update.

The materials offloading facility is now in full operation. Construction of the product loading jetty has reached the shoreline and the breakwater continues to take shape, Chevron said.

All six refrigeration compressors associated with LNG Train 1 have been installed. Work continues on the foundations of LNG Train 2.

According to the update, the concrete walls of LNG Tank 1 are nearing completion and the steel roof sections have been installed. LNG Tank 2 wall construction continues to progress.

Offshore facilities for the Wheatstone project  include Australia’s largest offshore gas processing platform, with a 225 kilometre trunkline connecting it to the onshore plant.

As part of the offshore project, seven of the nine development wells have been drilled to the top of the reservoir, Chevron said.

The steel gravity structure, the 35,000 metric-ton base of the Wheatstone gas processing platform, has arrived safely and is now set in place on the sea floor. The topsides are expected to be floated over and installed next year.

The final sections of the 44-inch, 140-mile (225-km) trunkline are now connected and laying on the sea floor. The trunkline is expected to be connected to the platform and onshore plant next year, Chevron added.
