Flexible Integrity & Inspection ,[object Object],[object Object],[object Object]

Riser Integrity ! Know the “important” failure modes Manage integrity Safer operations

Problems with Flexibles 1st - Outer sheath damage • Burst • Installation damage • Abrasion damage • Dropped object • 2nd - Aged internal sheath • 3rd - Internal sheath pull out • Obsolete through design / materials

Today's methods! ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

Flexible Piping inspection Over the last decade the oil industry has seen a vast expansion in subsea infrastructure and the use of flexible piping in production. The layered structure of flexible piping has posed challenges to inspection industry for years. AGR and there partners have now developed methods that vastly improve technical safety, meet international requirements and reduce the cost of inspection

Internal failures  internal inspection ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

North Sea base case Project Conclusion ,[object Object],[object Object],[object Object],[object Object]

External Inspection typical Failure Mode

[object Object],External Inspection Non Intrusive

[object Object],[object Object],[object Object],[object Object],[object Object],The solution

Scanning Detail Annulus scanning can both detect flooding and identify levels of corrosion on the internal amour wires. The scan data shows the method can detect missing wires

North Sea Operation The Inspection concept is now in operation and the photograph shows the interfaced Neptune being launched from an FPSO in February 2009

The integrated tool has the ability to clean the Flexible Pipe before latching on and scanning for flooding and armour wire degradation Cleaning and Latch on
