A method for the continuous remote monitoring of deformations of a pipeline configured for transporting a pressurized fluid, the method comprising the following steps: - installing a plurality of sensors on the pipeline, capable of transmitting and/or receiving guided waves generated in the form of elastic vibrations, wherein pairs of sensors (12A, 12B) are installed on respective sections of pipeline at a predefined distance; - performing one or more initial calibration measurements on each section of pipeline, wherein each of said initial calibration measurements is performed with the generation and propagation of guided waves by means of at least one sensor, and wherein the respective measured data are stored in a measured data vector A meas n, fk; - simulating the generation and propagation of guided waves on each section of pipeline, using a numerical model based on specific parameters typical of the pipeline and of the environment in which said pipeline is installed, wherein the respective simulated data are stored in a simulated data vector ( A sim n, fk); - repeating the simulation step until the deviation value ‖ A meas n, fk − A sim n, fk ‖ between the measured data A meas n, fk and the simulated data A sim n, fk is lower than a predefined threshold value (ε(n,f k)); - simulating the variation in said parameters, using said numerical model, so as to obtain values of said parameters which can jeopardize the integrity of the pipeline; - evaluating the deviation ‖ A meas n, fk − A sim n, fk ‖ between the measured data A meas n, fk and simulated data A sim n, fk as a function of the variation in said parameters for defining respective alarm thresholds (λ(n,f k)); - performing one or more effective measurements on each section of pipeline, wherein the measured data are stored in the measured data vector A sim n, fk; - repeating the step of performing one or more effective measurements until the deviation value ( ‖ A meas, current n, fk − A meas, previous n, fk ‖) between a certain current measurement A meas, current n, fk and the previous measurement A meas, previous n, fk exceeds at least one of said alarm thresholds (λ(n,f k)), the passing of at least one of said alarm thresholds ( λ(n,f k)) indicating that there are critical variations in the state of the pipeline, thus requiring further verifications and analyses. - installing a plurality of sensors on the pipeline, capable of transmitting and/or receiving guided waves generated in the form of elastic vibrations, wherein pairs of sensors (12A, 12B) are installed on respective sections of pipeline at a predefined distance; - performing one or more initial calibration measurements on each section of pipeline, wherein each of said initial calibration measurements is performed with the generation and propagation of guided waves by means of at least one sensor, and wherein the respective measured data are stored in a measured data vector A meas n, fk; - simulating the generation and propagation of guided waves on each section of pipeline, using a numerical model based on specific parameters typical of the pipeline and of the environment in which said pipeline is installed, wherein the respective simulated data are stored in a simulated data vector ( A sim n, fk); - repeating the simulation step until the deviation value ‖ A meas n, fk − A sim n, fk ‖ between the measured data A meas n, fk and the simulated data A sim n, fk is lower than a predefined threshold value (ε(n,f k)); - simulating the variation in said parameters, using said numerical model, so as to obtain values of said parameters which can jeopardize the integrity of the pipeline; - evaluating the deviation ‖ A meas n, fk − A sim n, fk ‖ between the measured data A meas n, fk and simulated data A sim n, fk as a function of the variation in said parameters for defining respective alarm thresholds (λ(n,f k)); - performing one or more effective measurements on each section of pipeline, wherein the measured data are stored in the measured data vector A sim n, fk; - repeating the step of performing one or more effective measurements until the deviation value ( ‖ A meas, current n, fk − A meas, previous n, fk ‖) between a certain current measurement A meas, current n, fk and the previous measurement A meas, previous n, fk exceeds at least one of said alarm thresholds (λ(n,f k)), the passing of at least one of said alarm thresholds ( λ(n,f k)) indicating that there are critical variations in the state of the pipeline, thus requiring further verifications and analyses.
