Prelude FLNG is under construction for the Royal Dutch Shell floating system for production, liquefaction, storage and handling of natural gas. When completed in 2015 it will be the world's first converted FLNG project (Floating Liquefied Natural Gas) and the largest floating offshore facility in the world.

Particulars

A FLNG is similar to a Floating Production Storage and Offloading Unit ( FPSO ) in crude oil production. The project, which in 2007 found off Australia Prelude gas field to be exploited, it was first started exclusively by Shell, meanwhile, from a consortium consisting of Shell was ( 67.5 %), INPEX ( 17.5 %) of the Korea Gas Corporation ( 10%) and the CPC Corporation ( 5%). The more than 12 billion U.S. dollar Prelude FLNG was given in July 2009 at a construction consortium consisting of Samsung Heavy Industries and the French engineering company Technip in order. Construction began in October 2012.

The double hull construction Prelude FLNG is 488 meters long and 74 meters wide. For the construction of 260,000 tons of steel will be required. At full storage capacity of liquefied natural gas ( LNG), the plant will displace approximately 600,000 tonnes. The annual production capacity is estimated at 3.6 million tonnes of LNG, 1.3 million tons of condensate and 400,000 tonnes of LPG.

On 3 December 2013, the flotation took place at the Samsung shipyard in Geoje.

Prelude FLNG in numbers

  • Around 600 engineers have been involved in the planning of the platform.
  • The platform will be 200 km away from the mainland in use.
  • The platform is about as long as four football fields in a row.
  • With the contents of the LPG tanks on board is enough to fill 175 Olympic swimming pools.
  • A motor speed of 6700 hp is required solely in order to keep the platform in position, which is additionally anchored in the seabed.
  • The platform each time requires 50 million liters of water, to cool the gas during liquefaction.
  • Six of the largest aircraft carriers together would displace the same amount of water as the FLNG.
  • 93 meters high, the spindle, which keeps the cables to secure the seabed.
  • At -162 ° C ( -260 ° F) natural gas is liquefied, the gaseous.
  • The liquefied natural gas occupies only 1/600 of the gas volume.
  • The plant is expected to produce gas in the amount of 117% of the gas consumption of Hong Kong.
  • 20 to 25 years the plant will operate on the gas fields in the sea.
