Technical Solutions & Qualifications
► 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
