Inpex Ichthys
BACKGROUND

The Ichthys LNG Project is ranked among the most significant oil and gas projects in the world. The Ichthys LNG Project is a Joint Venture between INPEX group companies (the Operator), major partner Total, CPC Corporation Taiwan and the Australian subsidiaries of Tokyo Gas, Osaka Gas, Kansai Electric Power, JERA and Toho Gas. Located about 220 kilometres offshore in Western Australia, it involved some of the largest offshore facilities in the industry, a state-of-the-art onshore processing facility and an 890 km pipeline uniting them for an operational life of at least 40 years.

 

SCOPE

BAM Clough JV were awarded the design & construct contract for the Module Offload Facility based on their design of using flat web sheet piles for a cellular structure in place of the more traditional designs in Australia of a land backed wharf or a deck on pile structure. J Steel and ArcelorMittal provided early budget pricing to BCJV & were subsequently invited to tender for the flat web sheet piles when the head contract was awarded. J Steel was awarded the contract for fabrication & supply of the sheets in January 2013 based on it’s capability to meet all the project design, quality and delivery requirements.

OUTCOMES

Due to the high loads on the Material Offload Facility the design required interlock resistance at a minimum of 5,500kN/m which the ArcelorMittal flat web sheets could achieve, where others couldn’t.
