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

ULTRASONIC INTELLIGENT SENSORS

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
