Raising the Roof on Curtis Island LNG

November 4, 2016

On the Curtis Island LNG project each of the two storage tanks has a capacity equal to 56 Olympic-size swimming pools. So how do you raise a roof weighing more than four Boeing 747s to put on the these tanks?

With air! 

Electric fans were used to lift the 850-tonne roof in two hours, using 4psi of air, about the same pressure it takes to blow bubbles through a straw in a glass of water. 

Check out this video to view an amazing feat of engineering!
