More than 600 engineers have worked on a massive project for the world’s first Floating Liquefied Natural Gas facility, which contains five times more steel than what makes up the Sydney Harbour Bridge.

The construction of the massive facility has been completed with the final fit out underway, including 3000 piping connections and over 450 kilometers of cabling. Once completed, it will be moved to the Browse Basin, which spans upto 200km from the West Australian coast line.

The Darwin Offshore Supply Base is going to be the base of maintenance for the enormous steel facility, keeping stock of spare parts and equipment for minor servicing. The annual operation and maintenance services contract will deliver about $200 million per year to the Australian economy, some of which will be linked to the Steel Supply and Manufacturers Industry.

The “Prelude” is 488m long and 74m wide, which makes it the worlds largest offshore floating facility ever built. It has approximately 260,000 of steel in it, which is around 5 times the amount of steel that was used in the construction of the Sydney Harbour Bridge.

It also has a 93 metre turret than runs through the floating facility, which is the same size as the Statue of Liberty. The storage tanks can hold the equilvalent of 175 Olympic sizes swimming pools.

The facility is expected to process 3.2 million tonned of Liquified Natural Gas per year.
