Abstract: Monitoring and analysis method of the conditions of a pipeline, comprising: providing an inspection device (1) in expanded polymeric or elastomeric material comprising at least one measurement instrument (2, 3), said measurement instrument including at least one casing and at least one sensor; introducing said inspection device into the pipeline (5); recovering said inspection device; wherein said casing is made of polymeric or elastomeric material, having a density, measured according to the regulation ASTM D3574, higher than or equal to 30 kg/m3, preferably ranging from 700 to 2,000 kg/m3. Said method allows the continuous registration and storage of useful parameters for revealing defects and/or anomalies inside the pipeline (5) that transports gas and/or liquids, as well as possible variations in the internal diameter of the same.

Abstract: A method for determining a position of a fluid discharge in an underwater environment, the method including: collecting data relating to an underwater area through at least two acoustic sensors; filtering and processing the data collected to identify the presence of the discharged fluid and the underwater area involved; forming a single stereoscopic image by combining the plurality of single three-dimensional images; and estimating the position of the fluid discharge on the basis of the stereoscopic image thus obtained.
