The two steel structures have a combined weight of more than 2,890 tonnes, and mark the completion of 15 million work hours over two and a half years to construct and deliver a total of 111 modules to the plant.
Built at Batangas in the Philippines, the modules make up the two LNG processing units – known as trains – that will convert natural gas into liquid by cooling it to -161ºC.
Santos GLNG Vice President Downstream Rod Duke welcomed the delivery of the final modules.
“The precision and expertise involved in building these vital pieces of infrastructure has been extraordinary,” Mr Duke said.
“Each module had to be built with a margin of error of only 2mm – an amazing feat when you think the heaviest weighed more than 2,500 tonnes and longest stretched nearly 75 metres.
“Importantly, construction work was completed with an excellent safety record, and I congratulate everyone involved for their efforts in safely reaching this milestone.”
Bechtel is constructing Santos GLNG’s two-train LNG plant on Curtis Island, off the coast of Gladstone.
