ULTRASONIC INTELLIGENT SENSORS
Subsea tieback to shore Challenges
• Time delay (long distance to shore)
• Remote
• Erosion
• Corrosion
• Clogging
ULTRASONIC INTELLIGENT SENSORS
How can we help
Permanent Monitoring
• Subsea sand monitoring per well
• Erosion monitoring per well
• Corrosion monitoring on critical lines
• Vibration monitoring on flex loops, connectors, risers, etc.
• Pig detection / monitoring
• Valve leak detection
Temporary Inspection
• Stand alone subsea and topside sand monitoring
• Subsea wall thickness measurements (UT)
• Subsea stand alone vibration monitoring
• Subsea and topside stand alone pig detection
ULTRASONIC INTELLIGENT SENSORS
Agenda
• Acoustic sand detectors (ASD)
• Acoustic PIG detection
• Acoustic leak detection
• Corrosion and Erosion Monitor (CEM)
• Vibration monitor
ULTRASONIC INTELLIGENT SENSORS
ASD – Acoustic sand detector
• Monitor sand production per well
• Non intrusive (not in contact with the flow)
• Passive acoustic (listen to the impact of solids / particle)
• Instant sand alarm
• Can quantify sand production
• 3000+ units installed subsea
• Interface with SPS
ULTRASONIC INTELLIGENT SENSORS
ASD – Acoustic sand detector
MSFR (Maximum sand free rate)
• Assets not designed for sand production – No sand tolerated
• Quantification of sand monitoring system not required
• No requirement for advanced system with process data input
• Instant alarm on sand production
• Qualitative measurements
MASR (Maximum accepted sand rate)
• Assets producing sand and can tolerate certain amount of sand
• Quantification required
• Process date required
• Accuracy important
• Instant sand alarm based on amount
• Quantitative measurements

APD – Acoustic pig detector
• Detects pig passage by acoustic and magnetic sensing
• Non intrusive (not in contact with the flow)
• Passive acoustic (listen to the sound of PIG)
• Instant indication
• Interface with SPS
• Topside and subsea
ULTRASONIC INTELLIGENT SENSORS
ALD – Acoustic leak detector
• Detects local leaks across valves, topside and subsea
• Non intrusive (not in contact with the flow)
• Passive acoustic (listen to the sound of leakage)
• Instant indication
• Interface with SPS
• Used for safety critical valves
ULTRASONIC INTELLIGENT SENSORS
CEM - What is it?
Permanent “active” acoustic, non intrusive wall thickness monitoring system.
