The present invention discloses a device and system for magnetographic analysis of mechanical flaws and defects along structures located underwater for example, metallic pipelines, utilizing an autonomous magnetic tomography method (MTM) apparatus based on the inverse magnetostrictive effect for magnetographic identification, in the form of an array of flexible autonomous undersea vehicle (AUV) torpedo constructions of interconnected elements or pods. The array of AUV torpedo constructions are flexibly linked together so that the device can readily navigate within the contours of pipeline to be inspected using the flow media as propulsion means or alternatively by means of independent motive means without interfering with the system flow. The torpedo construction elements or pods each contain three MTM sensors situated 120 degrees apart on a non-perpendicular cross section arrangement, and perform a variety of independent functions. e.g., data storage data, sensor data memory unit, odometer distance measurements, GPS location, geomagnetic navigation capability.
