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

Technical Solutions & Qualifications

► Products Qualification Process: Main Phases

All Technical Solutions Follow Stringent Qualification Process

and Gate Reviews

Phase 1 - Concept

Phase 2 - Feasibility

Phase 3 - Design Validation

Phase 4 - Industrialization

Benefit of Technip experience

and rigor regarding technical

products qualification process

► Riser Integrity Management Systems: Classification

INTERNAL

Monitoring

Systems

Intrusive monitoring

(ex: fiber optics)

Inserted within pipe or equipment at manufacturing stage

Taken into account during product design

For new risers only

EXTERNAL

Monitoring

Systems

Non intrusive monitoring

(ex: clamp)

May be retrofitted on existing pipe or equipment

No modification of product behaviour / No design issue

For already installed AND new risers

Development & Qualification of Dedicated Technology for Industry



► 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

• Detection of armour wire failure / rupture (vibration signature)

• Using fiber optics inserted within pipe armour layer

Distributed Vibration

Sensing(DVS)

• Instrumented rod (optical fibre) inserted within bending stiffener

• Allow real time curvature measure and allowing fatigue (re)assessment

CurvatureMonitoring

• Monitoring of pipe elongation and torsion

• Using fiber optics inserted within external fiber glass clamp

Torsion and Elongation

clamp (T&E)

• Detection of armour wire rupture acoustic signature

• Using external acoustic sensors (clamped on pipe)

Acoustic Emission

Monitoring

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
