  How Technip offers a broad range of flexible pipe systemswith the most advanced integrated solutions for deepwaterand ultra deepwater field developments Flexible pipe Engineering and technologies  2 With a workforce of 40,000 around the world, we constantly offer the best solutions andmost innovative technologies to our clients to meet the world’s energy challenges.We operate in three main businesses: Offshore In the Offshore business segmentTechnip performs engineering,procurement, construction,installation, commissioning and therefurbishment/upgrading of offshorefacilities for the oil and gas industry.Technip provides these services forfixed platforms in shallow water withconventional sub-structures andself-installing platforms such as theTPG 500 and for deepwater facilitiesincluding Spar, semi-submersible, TLP,FPSO and FLNG units. Technip is aworld leader in floatover installationof topsides and its R&D effort isfocused technology transfer for localcontent and new frontier areas suchas ultra-deepwater and the Arctic. Onshore Technip covers the full range of onshore facilities for the oil and gaschain, petrochemicals and otherenergy industries (nuclear, renewablesincluding biofuels and offshore wind).It holds many proprietary cutting-edge technologies and is the leader inthe design and construction of LNGand gas treatment plants as well asethylene, hydrogen and syngas units.Technip is also one of the key actorsin refining and petrochemical units,and has developed a leadershipposition in the fertilizer industry.Moreover, the Group is very active innon-energy activities such as miningand metals, life sciences, buildings andinfrastructures. Subsea In subsea hydrocarbon development,Technip’s activities include the design,manufacture and installation of rigid andflexible subsea pipelines and umbilicals.Thanks to its portfolio of technologiesand industrial and operational assets,Technip offers a unique verticallyintegrated model in the industry.The Group has 3 flexible pipemanufacturing plants, 4 umbilicalproduction units, 9 logistics and pipelineassembly bases, and 1 construction yard.Technip’s worldwide leadership issupported by a modern fleet of vesselsfor subsea construction, pipelaydevelopment (rigid and flexible pipesusing S-Lay, J-Lay or Reeled technology)and heavy lift applications. Technip is a world leader in project management, engineering andconstruction for the energy industry. Technip profile  3Flexible pipe Technip offers a broad range of services in engineering,manufacturing, installation and retrieval of flexible pipesystems with the most advanced integrated solutions fordeepwater and ultra deepwater field developments. Technip is the most experiencedprovider of integrated solutions forsubsea field developments, based ona broad range of field-proven productsand services. In the early 1970’s,Technip pioneered flexible pipetechnology and used it to provide itsclients with ever-higher levels of reliability and quality, even in theworld's harshest and deepest offshoreenvironments.For now 40 years, our high pressureflexible products have providedoffshore operators with reliable andefficient subsea solutions worldwide.To-date, more than 10,000km of Technip high-pressure flexible pipe hasbeen installed throughout the world.Our products are versatile, corrosion-resistant and compliant, and they areeasy and quick to install, retrieve andre-use for marginal or evolutive fieldarchitectures, thus environmentallyfriendly.They have carved out their place notonly for floating facilities but even inthe shallow and medium water marketsthat were once the exclusive domainof rigid steel flowlines. With internaldiameters ranging from 2 to 20 ,flexible pipes are the product of choicefor infield lines.At the same time, the flexible pipe'sversatility and ability to evolve withthe industry will continue to ensure itsplace within the deepwater and ultradeepwater markets that characterizenew offshore field developments. Standard Technip flexible structureIPB* (Integrated Production Bundle) *Proprietary technology  Flexible pipe  What is flexible pipe? 4Flexible pipe A fit-for-purpose structure A flexible pipe is made up of severaldifferent layers. The main componentsare leakproof thermoplastic barriersand corrosion-resistant steel wires. The helically wound steel wires givethe structure its high-pressure resis-tance and excellent bending characte-ristics, thus providing flexibility and superior dynamic behaviour. Thismodular construction, where the layersare independent but designed tointeract with one another, means thateach layer can be made fit-for-purposeand independently adjusted to bestmeet a specific field developmentrequirement. Main characteristics FLEXIBILITY Flexibility is the distinctive property of a flexible pipe. A typical 8'' internaldiameter (ID) flexible pipe can safelybe bent to a radius of 2m or less. Thisis the reason why flexible dynamicrisers have been the enabling techno-logy for floating production systems.This flexibility is also important forflowlines laid on uneven seabed condi-tions. Flexibility makes it possible tospool the pipe on a reel or in a carouselfor efficient and quick transportationand installation. INSTALLABILITY Because the flexible pipe comes in acontinuous length, laying speed commonly averages 500m per hour. Separate sections are connected ondeck during installation, eliminating theneed for any intermediate riser basestructure or subsea connections. Thiselimination of interfaces reduces riskin operation.In November 1971, the first Technipflexible pipe was installed in Congo. Ittook 1.5 hour to lay the 650m flowline,including connections. MODULARITY The independent layers of a flexiblestructure enable it to be tailored tothe precise needs of a specific deve-lopment. Simple flexible pipes formedium pressure water transportcomprise only four layers. The mostcomplex flexible pipes may have up to19 layers.Beyond the basic fluid barriers andstress-resistant wires, additional layerscan be included to prevent wearbetween steel layers (in dynamic appli-cations) or to provide improvedthermal insulation ( standard flexiblepipe already has a much better insula-tion coefficient than that of steel pipe).Besides including new thermoplasticor steel layers within the product, it isalso possible to assemble plastic hoses,electrical cables or optical fibersaround a flexible pipe to produce anIntegrated Service Umbilical (ISU®), orinclude active heating for flow assu-rance in deepwater to produce anIntegrated Production Bundle* (IPB).In 2001/2002, Technip participated inthe DEMO 2000 JIP, demonstrating itsability to supply heat traced flexible,including gas lift tubes and tempera-ture monitoring optical fibers withinthe same line (Integrated ProductionBundle). Heat tracing and monitoring allow temperatures to be perfectlytuned within the core productionflexible in order to meet flowing orcool down requirements. This type of flexible pipe provides an all-in-one solution for deepwater applications. Ithas been used several times in Westof Africa deepwater fields and will soonbe installed offshore Brazil. Corrosion resistance Since the steel wires are not in directcontact with the conveyed fluid, theydo not require the same corrosionresistance as steel pipe. This means thatour design experience and knowledgeof gas diffusion through thermoplasticmaterials enable us to use carbon steelwhere the equivalent rigid pipe appli-cation would require much moreexpensive corrosion-resistant alloys. *Proprietary technology
