ROV-Mounted Acoustic Leak Sensor

ROV-Mounted Acoustic Leak Sensor

Ultrasonic leak detection, utilizing directional hydrophones, identifies pipeline leaks by detecting ultrasounds from fluids under pressure. These signals, often above 30kHz, require advanced sensors and software to distinguish leak-generated sounds from ambient noise. Neptune Oceanographics' acoustic leak detection, deployable by divers or on ROVs, uses a directional hydrophone with noise filters. Detected signals are transmitted to the onboard PC, displaying acoustic intensity alongside fluorometer readings, allowing for precise leak identification.
