3 Introduction Integrity Management Main Purpose and Benefits: Forecast, predict and detect potential product failures Ensure and enhance safety of personnel, environment and equipments Allow durable and efficient risk management & fasten decisional process Optimize operators assests Industry Challenges Need for Integrity Management Technip Can Provide Solutions in the Integrity Management Domain 3

4 Integrity Management: The Technip way Integrity Management Philosophy: Corner Stones Integrity Management Solutions & Services Operators Needs Project specificities Integrated Approach With Qualified Personnel and Recognized Expertise Technip Objective is to Propose a Complete and Integrated Range of Products and Solutions 4

5 Integrity Management: The Technip way Collaboration Between Technip and Schlumberger On Dedicated Technologies and Services Collaboration Strengths R&D driven Experience Assets Presence Complementary Strengths = Best in Class Solutions & Products 5

6 Integrity Management: The Technip way Integrity Management activities: Products & Solutions Data Management & Interpretation Risk & Project Management IM Services Offshore Services 6

7 Integrity Management: The Technip way Risk Based Approach: Design Basis Design Improvement Identification of Failure Modes Integrity Management Plan Monitoring & Inspection Program Execution Data Management & Interpretation CONCLUSION (Riser Integrity or Life Extension) Lessons Learnt 7

8 Technical Solutions & Qualifications Products Qualification Process: Main Phases Phase 1 - Concept Phase 2 - Feasibility Phase 3 - Design Validation Phase 4 - Industrialization Benefit of Technip experience and rigor regarding technical products qualification process All Technical Solutions Follow Stringent Qualification Process and Gate Reviews 8

9 Technical Solutions & Qualifications Riser Integrity Management Systems: Classification INTERNAL Monitoring Systems EXTERNAL Monitoring Systems Intrusive monitoring (ex: fiber optics) Inserted within pipe or equipment at manufacturing stage Non intrusive monitoring (ex: clamp) May be retrofitted on existing pipe or equipment Taken into account during product design No modification of product behaviour / No design issue For new risers only For already installed AND new risers Development & Qualification of Dedicated Technology for Industry 9

10 Technical Solutions & Qualifications Self-set main criterions for solution choice: No maintenance / No interruption of production Possibility to upgrade the system Continuous monitoring Integrated Systems Advantages: Real-time visualization of conditions along the entire riser length Detection of events and associated localization Unique solution to generate traces both in space and time 10

11 Technical Solutions & Qualifications Distributed Temperature Sensing (DTS) Objective(s) Riser flow assurance Riser annulus flooding detection Principle Continuous annulus temperature measurement Using fiber optics inserted within pipe armour layer Qualification Level Qualified and in service since 2006 for flow assurance Test planned in Brazil Q for annulus flooding detection 11

12 Technical Solutions & Qualifications Riser Annulus Condition Surveillance (SubC-RACS) System Objective(s) Outer sheath integrity monitoring (breach detection) Measure of pipe annulus liquid level and free volume Gas sampling possibility Principle Continuous monitoring of gas diffusion rates, temperature and pressure Re-calculation of riser annulus free volume Qualification Level Tested at Flexi-France factory Offshore test completed (West Africa) QUALIFIED 12

13 Technical Solutions & Qualifications Distributed Vibration Sensing(DVS) Detection of armour wire failure / rupture (vibration signature) Using fiber optics inserted within pipe armour layer Curvature Monitoring Instrumented rod (optical fibre) inserted within bending stiffener Allow real time curvature measure and allowing fatigue (re)assessment Torsion and Elongation clamp (T&E) Monitoring of pipe elongation and torsion Using fiber optics inserted within external fiber glass clamp Acoustic Emission Monitoring Detection of armour wire rupture acoustic signature Using external acoustic sensors (clamped on pipe) 13

14 Data Management & Interpretation Surveillance System Data Delivery Real-time data delivery from wellsite Connects to proprietary and 3rd party database Data Intepretation Raw data is not enough Need for the right data with the right format Key Point: Flexible Pipe Expertise & Knowledge Raw Data Analysis & Interpretation Conclusion & Solutions 14

15 Offshore Services Monitoring & Inspection Offshore Repair & Maintenance Technical Expertise Annulus testing External sheath repair Qualified & trained personnel ROV survey / Video inspection / Others End-fitting mounting Qualified procedures Monitoring Systems commissioning Training of operators maintenance teams Flexible pipe experts support Performed by Qualified Personnel - Extensive Track Record 15

16 TRACK RECORD Existing Track Record Concerning flexible pipes And other subsea equipment (rigid pipes, subsea modules etc) Vent Gas Monitoring Polymer Coupon Monitoring Distributed Temperature Monitoring Integrity Management Plans Definition & Implementation Project Management Monitoring Solutions Already in Service Around the Globe 16

17 CONCLUSION Integrity Monitoring : Real Added Value for Operators & Technip Technip Philosophy Integrated approach From design and manufacturing to offshore support Collaboration with Schlumberger brings complementary expertises Technical Solutions and Services Available Technical expertise and knowledge Stringent qualification process Assess Riser service life function of actual service conditions Way Forward Flow assurance management (cold spot, hydrates, slugs...) Production optimisation 17
