Gas and Oil giant company Shell laid the keel for the first floating liquefied natural gas (FLNG) project in the world - Prelude FLNG (the new biggest ship in the world). The new FLNG project of Shell is going to be the world's biggest ship / facility ever built. The hull of the new FLNG project is scheduled to be built in the dry dock before the topsides and the turret of the facility are fitted at the South Korean shipyard of Samsung Heavy Industries.

The Executive Vice President Projects of Shell, Rob Kretzers stated: “This is a key milestone in Prelude’s story. Innovative thinking and leading edge technology, as well as hard work from those at Shell and our partners, have helped us reach this significant point in construction. Prelude’s size and scale is unprecedented and I look forward to seeing this enormous structure take shape. Shell is pioneering FLNG which has the potential to revolutionise the way natural gas resources are developed”.

The first liquefied natural gas project in the world is going to give the chance of Shell to produce LNG directly at sea, turning it into LNG and next transferring it directly to the vessels, which are going to transport the produced LNG to customers. The new FLNG project for the biggest ship in the world of Shell is going to provide new perspectives for countries, which are trying to develop their gas resources and bring more liquefied natural gas to the market.

Prelude FLNG project in numbers

  • >600 engineers worked on the facility’s design options
  • >200 km (125 miles) distance from the Prelude FLNG field to the nearest land
  • 4 soccer fields, laid end to end, would be shorter than the deck of the biggest ship in the world
  • 175 Olympic-sized swimming pools may hold the same capacity of liquid as the FLNG's storage tanks
  • 6,700 horsepower thrusters are going to be used to situate the biggest ship in the world
  • 50 million litres of cold water are going to be drawn from the ocean each hour in order to cool the liquefied natural gas system
  • 6 of the largest aircraft carriers are able to displace the same amount of water as the facility
  • 93 metres is the height of the turret, which runs through the FLNG project, secured to the seabed by mooring lines
  • -162° Celsius (-260°F) is the temperature at which natural gas turns into LNG
  • 1/600 is the factor by which a volume of natural gas shrinks when it is turned into LNG
  • 117% of Hong Kong’s annual natural gas demand may be met by the FLNG facility’s annual production of liquefied natural gas
  • 20-25 years is the time the Prelude FLNG facility is going to stay at the location to develop gas fields

Key contractorsTechnip Samsung Consortium

Over 1,600 of large steel selections called "blocks" are going to form the hull of the new FLNG project and biggest ship in the world are already accomplished in the Geoje shipyard in South Korea, remaining blocks are being manufactured. Just for information, the size of one block section is as a big house.

World's first FLNG Project Construction

The turret system for mooring of the new biggest ship in the world will be 93-metres in height and is currently under constructions in Dubai. It is planned to be transported the Samsung shipyard in South Korea in 5 parts due to their seize. The turret system is going to run vertically through one end of the FLNG project and is planned to be anchored to the seabed by 4 groups of mooring lines. This mooring system is going to allow the FLNG project to rotate with the wind direction.

After the completion of the FLNG project the facility will become the biggest ship in the world with its respectful 488-metres length, which is 88 metres more than the length of the "current" biggest ship in the world Maersk Mc-Kinney Moller and longer than 4 soccer fields. The FLNG project will weight 600,000 tonnes and will be able to displace 6 times as much water as the biggest aircraft carrier in the world. The biggest ship in the world is going to be moored and hooked up to the undersea infrastructure, which is located at about 256 nautical miles north-east of Broome in Western Australia.

Even though the FLNG project will be the biggest ship in the world, she is going to be only 1/4 of a plant on land equivalent. The new technology of Shell is adjusted for floating liquefied natural gas, and the Shell's team of engineers has designed components, which are going to stack vertically so they can save space. For instance, the plant for cooling the LNG is planned to be situated just above the huge LNG storage tanks with capacity of almost 175 Olympic swimming pools. The cooling process of the liquefied natural gas will need 50 million litres cold water, which will be stored in specially projected tubes, known as risers.

Shell FLNG - Biggest Ship in the World

The oil and gas giant Shell is guiding the mega FLNG project for constructing the biggest ship in the world in long-term strategic cooperation with Technip and Samsung Heavy Industries (the Technip Samsung Consortium).
