ACCOUSTIC SUBSEA PIPELINE - LEAK DETECTION SYSTEM (APLD)

The acoustic method uses 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 that determine the difference between leak generated sound and lower frequency noise such as that caused by the attendant ROV and surface vessels.

Standard Features :

  • 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
