PECAT™
The Assessment Of The Effectiveness Of
Cleaning Programmes
Company Proprietary - Not For Distribution
Why Carry Out A Cleanliness Assessment
Why would an operator want to measure debris
• To ensure the pipeline cleaning programme is efficient
• Annually measure debris findings, preventing future problems
• Identify features and ID anomalies
• In advance of ILI programmes
Why does this matter
• Ensuring successful ILI surveys
(first run success rate)
• Ensuring effective cleaning and treatment programmes
• Proactive approach to prevent stuck pigging tools
The presence of internal debris can compromise pipeline integrity

Measurement Capability
By using Hall Effect Sensors combined with small permanent
Magnets, PE can measure:
• Features which are in the range of 0 – 20mm
• HR Caliper measuring from 1 – 60mm deflection
Dents
ID changes
Ovality
• Any non-ferrous debris
• Wax (hard and soft)
• Scales
• Sand / Sand in wax
• Black Powder (limitations)
PE Would not recommend this type of tool to detect hydrates, as the
risk of blockage is too great

Black Powder Testing
See full black powder assessment on slide 14, summary below:
Stand off: Offset sensors will be able
to detect black powder is present.
Signal: Small offset differences in
voltage signal.
Pick Up: Small quantities stick to the
magnets but once magnetised the
mutual repulsion prevents further
pick up.
