The company told the Singapore Exchange late on Wednesday that its subsidiary AGC Industries was awarded the extension to fabricate more pipe spools for the project.
This further work has been valued at about A$13.6 million (US$13.92 million), bringing the total contract value up to more than A$80 million.
The original deal had AGC fabricating 12,000 pipe spools at its manufacturing and fabrication facilities in Kwinana and Henderson, Western Australia.
