A unique Distributed Vibration Sensor system that is effective in the prevention of oil or gas spills due to its unique ability to detect, locate and classify vibrations caused by physical activity (such as third party interference), while simultaneously monitoring for early-stage leaks, along the entire length of the pipeline in real time. This unique technology acts as a continuous microphone, up to 50km in length, designed to “monitor” over an unprecedented quasi-DC to 500kHz bandwidth, to very distinctive frequencies generated by acoustic TPI and ultrasonic leak events, while discriminating between normal and ambient conditions.
