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.

PETRONAS Award date: February 2011 Client: Petronas and MISC Berhad Contractor: Technip, in consortium with DSME FEED contract for an FLNG unit, offshore Malaysia Capacity: 1.2 Mtpa EPC contract awarded in  June 2012 Keel laying in January 2013 Hull launch in April 2014

These awards confirm Technip's position as the leading FLNG engineering contractor

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

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

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.

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.
