A method and a system are described for the remote detection of the position of a pig device (10) inside a pipeline (12) for transporting pressurised fluids, like for example long distance oil and gas pipelines having a strategic international value. The method foresees equipping the pipeline (12) with pressure sensors (14) in contact with the fluid, located at at least one of the two terminals (A, B) of the pipeline (12), and the sending and processing of signals by means of a control unit (16). The operation of the system is that of identifying and locating, in real time and continuously, a pig device (10) that moves intermittently inside the pipeline (12), for example during cleaning, monitoring, measurement and non-destructive control operations.

Abstract

A method and a system are described for the remote detection of the position of a pig device (10) inside a pipeline (12) for transporting pressurised fluids, like for example long distance oil and gas pipelines having a strategic international value. The method foresees equipping the pipeline (12) with pressure sensors (14) in contact with the fluid, located at at least one of the two terminals (A, B) of the pipeline (12), and the sending and processing of signals by means of a control unit (16). The operation of the system is that of identifying and locating, in real time and continuously, a pig device (10) that moves intermittently inside the pipeline (12), for example during cleaning, monitoring, measurement and non-destructive control operations.
