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.
