Almost eight million tonnes per annum (mtpa) of the world's LNG production will be exported from four floating LNG (FLNG) production units by the end of this year.

Two of these — Shell’s Prelude FLNG off Australia, the world’s largest, and the Exmar-owned, YPF-chartered Tango FLNG in Argentina, at the smallest end of the scale — are exporting their first cargoes this month.
