SYSTEM AND METHOD FOR THE CONTINUOUS DETECTION OF IMPACTS ON PIPELINES FOR THE TRANSPORTATION OF FLUIDS, PARTICULARLY SUITABLE FOR UNDERWATER PIPELINES

摘要

The present invention relates to a system and method for the continuous detection of impacts on pipelines for the fluid transportation, particularly on pipelines placed on the seabed, wherein the system comprises at least two sensors (11, 12) each installed in correspondence with an end of a section subject to detection (x) of a pipeline (13) and it is characterized in that a first sensor (12) of said at least two sensors (11, 12) is suitable for detecting first acoustic waves (14), which propagate along a first transmission phase associated with said pipeline (13) and a second sensor (11) of said at least two sensors (11, 12) is suitable for detecting second acoustic waves (15) which propagate along a second transmission phase associated with said pipeline (13), the second acoustic waves having different elastic features with respect to said first acoustic waves.
