Major FLNG contracts signed since 2009
FLNG is a true representation of
Technip's technological differentiation
through the integration of all our core
activities: LNG process, offshore
facilities and subsea infrastructure
FLNG solutions have the potential to place gas
liquefaction facilities directly over offshore gas
fields, thereby precluding the need for long
distance pipelines and extensive onshore
infrastructure.
This innovative alternative to traditional onshore
LNG plants provides a commercially attractive
and environmentally friendly approach for
monetisation of offshore gas fields.
SHELL
Generic FLNG
On July 28, 2009, two contracts were signed in Paris with Shell:
a master agreement with a consortium comprising Technip and Samsung for the design, construction and installation
of multiple floating liquefied natural gas (FLNG) facilities over a period of up to fifteen years.
a contract with the same consortium for the execution of the front end engineering and design (FEED) for Shell's
3.6 Mtpa FLNG solution.
Prelude FLNG, Western Australia
On March 8, 2010 a contract was signed in Paris with Shell, covering the FEED elements specific to the Prelude project,
taking into account the composition of the gas, local weather conditions and other site-specific factors.
On May 30, 2011, Shell gave notice to proceed with the detailed design and construction of Prelude, the first FLNG
facility in the world.
On June 29, 2012, Shell awarded Technip a large subsea installation contract, including management of key interfaces with
the hook-up and commissioning of the Prelude FLNG facility.
Agreement to strengthen FLNG collaboration
In December 2012, Shell and the Technip-Samsung Consortium signed an
agreement to enhance collaboration on the design, engineering, procurement,
construction and installation of future innovative FLNG solutions across a wide
range of opportunities in the
future. For example, Shell’s FLNG
Lean technology would be able
to process additional gas and
produce more LNG, opening up
new business opportunities for
countries looking to develop
their gas resources.

Addressing FLNG challenges
Technip has strong technical skills in many of the areas
critical to FLNG.
New tools and solutions have been developed or existing
methods adapted to meet the specific needs of FLNG
vessels operating in harsh environments.
Process schemes
Improved processes have been developed by Technip’s
process engineers to meet the requirements of the new
context of Floating LNG, including:
Ideas for improving natural gas liquefaction
Gas condensate stabilisation producing a rich gas for
direct liquefaction without LPG production
Production of high purity N2 from the natural gas
NG
LNG
G
Wave basin model tests - Scale:60
High efficiency offshore "reverse Brayton" type liquefaction process
Hull motions
The design of topside equipment requires the
collaboration of an entire team of naval architects, piping,
process and equipment engineers, critical equipment
suppliers, installation specialists and engineers skilled in
advanced numerical modelling.
Sloshing in a horizontal drum
equipped with baffles
Accelerations are quantified and loads on mechanical
equipment checked with vendors.
The effects of hull motions on gas/liquid separation in
process equipment are studied, when necessary, with
process licensors and suppliers.

Safety - Risks from cryogenic and
hazardous fluids
The challenge for the safe layout of an FLNG facility is the
large process area required in a reduced footprint leading
to relatively high congestion and tall modules.
Our risk-based approach assesses potential consequences
and associated frequencies to derive appropriate
safeguards and mitigation measures. Among process risks
(fire and explosion) and non-process risks (ship collision,
dropped object, etc.), the hazards of personnel and asset
exposure to cryogenic fluids are specific safety drivers.
As a prime example, the potential consequences of
cryogenic spillage on deck and hull structures are studied
to define the best counter measures.
Naval architecture
Naval Architects had to address several new challenges:
Sheer size - larger than any existing FPSO
Harsh environmental conditions
Weathervaning systems suitable for the 10,000-year
storm
LNG cryogenic transfer between two floating units in
the open sea
Accommodating a wide range of LNG and LPG carriers
The development of the FLNG/TMS solution for Shell
Prelude was enabled by combining Technip's
marine/MetOcean expertise with that of Shell, SBM and
Samsung.
Design solutions are helped by a series of two tests:
Wind tunnel tests to derive wind and current loads on
the FLNG with and without an LNG carrier present.
Wave basin model tests with FLNG and LNG carriers
covering:
Mooring in harsh, category 5 cyclone conditions
Decay and motion response tests
Berthing and mooring and the equipment required
between the two vessels
The loads generated when towing these large units
Experimental validation of models for cryogenic spill
Interface management
The objective is to minimise the potential for escalation
and promote safe escape. In the event of major accidents,
the goal is evacuation and rescue of personnel while
maintaining asset integrity.
FLNG flare radiation at deck level is potentially much
higher than for conventional FPSO’s requiring the use of
state-of-the-art modeling tools.
Flare flame radiation

Determination of flare structure
temperatures under the effect of
radiation
FLNG projects have an increased number of design and
construction interfaces. To mitigate the risk from poor
management, Technip has developed and is using a
specific Interface Management Tool - IMT, that allows full
technical and commercial alignment between multiple
parties at each interface.
