1. A method for detecting leaks in pipelines comprising the steps of:

  • interconnecting sensors at a plurality of locations along a pipeline for sensing fluid acoustic pressure in the pipeline at the plurality of locations;

    interconnecting local site processors with the sensors at the plurality locations along the pipeline;

    obtaining past fluid acoustic pressure data associated with past leaks in pipelines;

    storing the past fluid acoustic pressure data associated with past leaks in the local site processors;

    sensing fluid acoustic pressure in the pipeline at the plurality of locations with the sensors;

    comparing the sensed fluid acoustic pressure data with the past fluid acoustic pressure data in the local site processors; and

    issuing an alarm if the sensed fluid acoustic pressure data matches the past fluid acoustic pressure data.
