After three and a half years of construction work, Santos GLNG has installed the final module on its two LNG processing trains, key components of its gas liquefaction plant on Curtis Island near Gladstone.
The last of the 111 modules used to build the two trains was installed earlier this week. Train 1 comprises 82 modules while Train 2 comprises 29.
Santos GLNG General Manager Downstream Operations Brenton Hawtin said the construction of such a vital part of the plant often referred to as “the big fridge” was a key milestone for the project.
“LNG trains are essentially big refrigerators that will take natural gas piped from our Queensland gas fields and condense it into liquid form so it can be safely and efficiently shipped. Once we’re in full production, these massive pieces of infrastructure will together produce up to 7.8 million tonnes of liquefied natural gas each year.”
Each module had to be built with a margin of error of only 2mm, with the heaviest weighing more than 2,500 tonnes and longest stretched nearly 75 metres.
The modules were constructed in Batangas in the Philippines and shipped to Curtis Island individually.
Hawtin said setting the last module into place was the latest in a series of key milestones across Santos GLNG.
“In the past few weeks, we’ve put first gas in our pipeline, completed our first major processing hub in our gas fields and finished hydrotesting our second LNG storage tank on Curtis Island,” Hawtin said. “Final pipework and cabling on the trains will now take place before commissioning of the plant begins later this year as we look towards first LNG in 2015.”
Bechtel is constructing Santos GLNG’s two-train LNG plant on Curtis Island, off the coast of Gladstone.
Santos GLNG is a joint venture between Santos, Petronas, Total and Kogas.
