Floating liquefied natural gas (FLNG) is a revolutionary technology that will allow Shell to access offshore gas fields that would otherwise be too costly or difficult to develop. Prelude FLNG is the world's first FLNG development. The installation is 488m, and the largest floating offshore installation on the planet. Ten years of R&D have been spent on this project, of which a large part took place in Amsterdam. Shell builds on her knowhow of offshore production. The FLNG technology is an important extension of onshore-LNG.
