Float out of Prelude FLNG

Shell's Prelude, the 488 meter long hull of floating liquefied natural gas (FLNG) plant has been floated out of the dry dock at the Samsung Heavy Industries (SHI) yard in Geoje, South Korea, it has been under construction there for just over a year.

This vessel will be the largest floating structure ever constructed, weighing 600,000 tons fully loaded. It's LNG tanks can store up to 220,000 m3 of LNG, 90,000 m3 of LPG, and 126,000 m3 of condensate, or a total capacity equivalent to approximately 175 Olympic swimming pools. 

Prelude FLNG will be moored 200 kilometers off western Australia at the Prelude gas field, it is expected to produce the equivalent of 110,000 BOE per day for 25 years.

It will be able to withstand Category 5 cyclones, secured by one of the largest mooring systems in the world. A 93-meter (305-foot) high turret will run through the facility while four groups of mooring lines will anchor it to the seabed. Three 6,700-horsepower stern thrusters, two of which will operate at any one time, will be used to pivot the facility either out of the wind or to allow LNG carriers to pull safely alongside to load.

Neil Gilmour, Shell Vice President Integrated Gas Development. said “This is revolutionary technology developed by Shell. It has the potential to change the way we produce natural gas.”

The Prelude FLNG is due to be fully operational by 2017 and analyst say it may cost over $12 billion to build.
