A method for the continuous remote monitoring of the integrity of a pressurized pipeline and properties of the fluids transported, that can be used in long-distance gas pipelines and oil pipelines, comprising the following phases: - installing a plurality of measurement stations along the pipeline, connected to vibroacoustic sensors, suitable for simultaneously and continuously measuring elastic signals propagating in the walls of the pipeline, and acoustic signals propagating in said transported fluid; - synchronizing said measured signals x(t), with absolute time reference, measured by said different measuring stations; - continuously transmitting said measured and synchronized signals x(t) to a central unit suitable for processing them in a multichannel mode; - calculating, by means of said central unit, a plurality of transfer functions H(f) suitable for defining the vibroacoustic propagation in sections of the pipeline between consecutive measurement stations using, as analysis signals, said measured and synchronized signals x(t) and the corresponding Fourier transforms X(f); characterized by: - continuously updating said transfer functions H(f) using acoustic and elastic signals generated by passive sources present along the pipeline, preferably selected from pumps, compressors and / or flow regulating devices by - filtering the acoustic and elastic signals detected by the different measurement stations, subtracting the contribution related to the passive sources from the signals acquired by pairs of measurement stations 103 positioned close to the passive sources; - creating an equivalent descriptive model of the system comprising the fluid transported, pipeline and external medium surrounding the pipeline itself, using said transfer functions H(f) connected with each other. - installing a plurality of measurement stations along the pipeline, connected to vibroacoustic sensors, suitable for simultaneously and continuously measuring elastic signals propagating in the walls of the pipeline, and acoustic signals propagating in said transported fluid; - synchronizing said measured signals x(t), with absolute time reference, measured by said different measuring stations; - continuously transmitting said measured and synchronized signals x(t) to a central unit suitable for processing them in a multichannel mode; - calculating, by means of said central unit, a plurality of transfer functions H(f) suitable for defining the vibroacoustic propagation in sections of the pipeline between consecutive measurement stations using, as analysis signals, said measured and synchronized signals x(t) and the corresponding Fourier transforms X(f); - continuously updating said transfer functions H(f) using acoustic and elastic signals generated by passive sources present along the pipeline, preferably selected from pumps, compressors and / or flow regulating devices by - filtering the acoustic and elastic signals detected by the different measurement stations, subtracting the contribution related to the passive sources from the signals acquired by pairs of measurement stations 103 positioned close to the passive sources; - creating an equivalent descriptive model of the system comprising the fluid transported, pipeline and external medium surrounding the pipeline itself, using said transfer functions H(f) connected with each other.
