Acoustic Subsea Pipeline Leak Detection Systems

Acoustic Subsea Pipeline Leak Detection Systems The Acoustic Subsea Pipeline Leak Detection Systems use directional hydrophones that 'listen' for ultrasound generated by leaking fluids under pressure. The acoustic signals generated by a leak tend to be at frequencies above 50kHz. The software uses techniques to determine the difference between leak generated sound and lower frequency noise such as that caused by the attendant ROV and surface vessels. Standard Features of the system: • Hydrophone can be diver held, ROV or AUV mounted • Directional hydrophones listening ‘cone’ approx. +/-12 degrees • The system is quickly mobilised for offshore operations worldwide • Graphical display and data logging • Operating depth to 1,200m • Compatible with Neptune’s two channel leak detection system to allow simultaneous operation with other leak detection sensor types
