FLNG: the combination of our know-how
A FLNG is longer and wider than other vessels. This is to accommodate the topside equipment and to provide sufficient LNG storage volume in the hull. Topside weight is typically double that of other large offshore production platforms. The LNG is transferred to a LNG carrier. The volume of the FLNG’s tanks must be enough to fill completely an LNG carrier, plus an allowance to cater for continued production during bad weather when LNG transfer isn’t possible.

FLNG (Floating Liquefied Natural Gas) is the first project type which involves so many of Technip’s skills. It is the concretization of decades of work for the Group in LNG process plant, floating offshore facilities and subsea infrastructure. FLNG is also an excellent example of differentiation through the integration of multiple, core activities to produce something new.
FLNG design requires prior knowledge of: natural gas liquefaction; the design and construction of large FPSOs (Floating Production Storage and Offloading) that up until now have been used only for oil production; and the design of the riser and mooring systems that link offshore gas fields with floating platforms. Technip has the unique ability to provide expertise in all these key areas, with recent successful references through projects such as Yemen LNG, Akpo FPSO in Nigeria and the subsea project MAD6 in India. Many new design challenges have been overcome by our teams to have:
- compact and motion resistant processes that produce high quality LNG;
- layout features and passive and active safety systems that safeguard life and property;
- piping and structural elements that resist the long term fatigue from the battering of wind and waves.
In July 2009, Shell signed a 15 year umbrella contract with the Technip Samsung Consortium for a program of generic FLNGs. Today, the construction of Prelude FLNG is well underway in our partner’s shipyard in Goeje, South Korea, while the original agreement has been extended to cover innovations for the next generation of Shell FLNGs that are at design stage in Paris La Défense in France.
Then, in June 2012, a contract to supply Petronas with a small capacity FLNG was signed with Technip and Daewoo, a project jointly managed by the Kuala Lumpur and Paris centers. These are the only two FLNGs under execution to date in the world, making Technip the uncontested market leader.
