Why Internal Corrosion Monitoring?
Corrosion Management
• Correlate process parameters with measured corrosion
• Monitor (change in) corosivity of pipeline fluids
• Control of corrosion mitigation/inhibitors
• High resolution and fast response required from the sensor.
Integrity management and safety verification
• Risk of unexpected failure and accidents
• Avoid loss of containment
• Optimize (risk based) inspection programs and planned maintenance
• Reliable wall thickness measurements over time required, high resolution/fast response less important.

• Measures erosion directly
• Superior sensitivity (+/-5 nanometers or 0.0002 mils)
• Reference element in protected location (rear)
• Multiple elements for redundancy & coverage of entire pipe
diameter
• Operates in all flow regimes

Sand Monitor Sand Monitor – Topside Applications
Clamp-on sand detection system with a non-intrusive design
Based on acoustic technology (Utilizes the acoustic noise
generated by sand particles impacting the inner surface of the
production pipework to identify and calculate real-time sand
production in any water, oil, gas or multiphase pipeline flows)
High sensitivity
All data processed internally & stored in flash memory
Local status display (LED)
No need for a computer in daily use
Sand Monitor - Subsea
Provides real-time quantitative monitoring of sand in the production
flow
Based on passive acoustic technology
Maintenance free
Low power consumption
Two-way communication
Functional error checking

Combining erosion based and acoustic systems
Redundancy – two alternative measurement principles
Best of two worlds
– Acoustic -> immediate response on sand changes
– Intrusive -> ”direct erosion measurement”, quantifies sand when combined with flow rates
Improved alarm settings
Trend towards using both acoustic and intrusive sensors
Can be integrated in one Roxar Sand Management system, using same Fieldwatch software.

• Sand/erosion data used for determining
maximum sand free rate.
• Production rate increased until sand
production starts, then flow rate reduced
until acceptable sand free level
• Sand burst detected from sand data
• Well choked back until sand production stopped
• Sand burst detected after minutes – incident under
control
• Accumulated metal loss of 5.2 µm
• Metal loss during sand burst corresponds to 10
mm/year risk to well and infrastructure
