More Subsea Tools
The F-Bolt Scanner tool:
The bolt scanner uses ultrasound to detect
cracks in bolts in situ on a subsea
construction, making retrieval unnecessary.
The F-Chain measure scanner:
For measuring chain wear. Can be done in situ. The
system is based on ultrasonic technique.
Internal Armour Inspection ( Flexible Pipes )
Internal:Carcass and hoop armour
Failure modes: unlocking, fatigue cracks
End fitting inspection
External: tension armour
Failure modes: fatigue cracks, corrosion
Repeated inspections = Monitoring

Risk Based Inspection (RBI)
You inspect critical points.
With use of knowhow and
experience, it is possible to focuson the high risk points on yourStructure/main steel, and with theinspected data from these points,
you know something about theintegrity of the total structure.

Summary / The best way of knowing
Steel structures offshore and onshore may
degenerate because of:1. Erosion2. Fatigue
3. Corrosion
4. Extreme loads Theory and knowhow is getting better and we are
able to forecast most of the degeneration
But for verification of our estimate, inspection and
monitoring is needed. Data from Inspection and Monitoring is the key to be
better in what we do.
