Floating Liquefied Natural Gas Vessel (FLNG)


The “conventional” approach to producing LNG is to pipe the gas from the field – which may be hundreds of kilometres offshore - to an onshore plant to be processed and liquefied. The gas is then stored on site before being offloaded to a LNG tanker to be taken to market.


This method is costly, as it needs pipeline to connect the field to the export terminal, it needs coastal works and an onshore processing plant and may cause disturbance to the seabed.


In this context, some companies have imagined and develop the concept of performing the liquefaction operations offshore, just above the gas field to reduce infrastructures and save all extra costs.


Floating liquefied natural gas vessel, or FLNG, is designed to operate on offshore gas fields in which the gas will be extracted from the seabed, then processed, liquefied and stored on a floating facility that will be permanently moored over the field. FLNG condenses the gas into a liquid form by cooling it till approximately -162C (-260F) thus allowing large volumes of liquefied natural gas to be stored on the vessel. The LNG will then be offloaded on a tanker and taken directly to market.

FLNG has less impact on the environment than conventional LNG processing.


Group B&T is able to supply pipe, fittings and flanges requirement in a FLNG vessel construction. Our group can satisfy your requirement by procuring specialty pipe for flowlines (seamless pipes) and gas export lines (welded pipes). 


Group B&T  source and supply pipes in stainless steel, duplex, super duplex, nickel alloy, carbon and low carbon temperature steel pipes, fittings and flanges along project management services which includes testing, fabrication, inspection and delivery as scheduled.
