FIELD: transportation.
SUBSTANCE: method comprises the steps of detecting defects along a underwater pipeline using a submerged module using a magnetic tomography method (MTM module) in the immediate vicinity of the underwater pipeline; and determining the position of the submerged MTM module under the water and thereby locating the defect. The method further comprises determining the position of the submerged MTM module relative to the surface vessel; and the determination of the absolute position of the surface vessel.
EFFECT: improving the accuracy of the defect detection.
