## Abstract

A buried hydrophone may be configured to identify real-time changes in pipeline acoustics and vibrations during a flood event. Monitoring vibrations may allow predicting the likelihood of pipeline exposure and suspension.

## Claims

### Claim 1

A system, comprising:
a sensor, the sensor operable to detect vibrations;
a data acquisition unit, operable to receive input from the sensor;
a processor, operable to receive input from the data acquisition unit;
a telemetry transmitter, operable to receive input from the processor and transmit it to a computer; and
a power supply operable to provide power to the data acquisition unit, the processor, and the telemetry transmitter.

### Claim 2 (depends on 1)

The system of claim 1, wherein the sensor is a hydrophone.

### Claim 3 (depends on 1)

The system of claim 1, wherein the sensor is a vibration sensor comprising an accelerometer.

### Claim 4

A method, comprising:
measuring a baseline vibration profile for a pipeline;
sensing a vibration in the pipeline;
detecting a difference between the baseline vibration profile and the sensed vibration in the pipeline; and
predicting a likelihood of pipeline exposure and suspension based on the detected difference.

### Claim 5

A computer-readable storage device with instructions thereon which, when executed, perform a method comprising:
sensing a vibration in the pipeline;
detecting a difference between a previously measured baseline vibration profile and the sensed vibration in the pipeline; and
predicting a likelihood of pipeline exposure and suspension based on the detected difference.
