Pluto LNG Project

Project data

Location: Perth, Australia

Chicago Bridge and Iron (CB&I) is playing an important role in the development of the $12 billion Woodside ‘Pluto’ LNG project on Western Australia’s Burrup Peninsula near Karratha. The Pluto project is the world’s fastest developed gas project, with gas began  flowing in 2010 – just five years after discovery of the field in 2005.


  • Two huge on-shore 120,000 cubic metre steel and concrete
  • Storage of liquefied natural gas (LNG) from Woodside’s Pluto and Xena gas fields in the Carnarvon Basin


  • A total of 11 wall lifts to each of the reinforced, prestressed concrete tank walls
  • Over 10,000 cubic metres of wall concrete

Benefit to customer

  • PERI Engineering Support was readily provided and the PERI Representative frequented site on a number of occasions where queries needed to be addressed.

PERI solution

  • PERI Vario system was selected so that the formwork could be pulled back from the concrete after pouring and jumped (or lifted) up by crane to the next level.
  • Steel reinforcing was safely fixed from the top deck and Vario’s versatility allowed top reinforcement tying works to be carried out safely from behind the shutters (when retracted) after the shutters were jumped.
  • Stringent quality controls were applied throughout the project, including stringent material certification requirements to verify the steel quality of the PERI hex nuts and similarly tight controls on the quality of welds which attached the nuts to the liner to engage the DW15 ties.
