ABSTRACT:
The location of a pig in a conduit, e.g., an underwater pipeline, may be determined by measuring an amount of a fluid displaced by the pig from the conduit and calculating the location of the pig in the conduit based on that amount of fluid. In particular, the amount of the fluid displaced by the pig may be measured using a flow meter positioned near an exit of the conduit. This amount may then be transmitted to a computer for calculating the location via, for example acoustic telemetry. The location of the pig may then be transmitted from the computer to a receiving device for receiving and displaying the location.
