Zusammenfassung:	The present invention is directed to a system and a method for inspecting a subsea pipeline. The method comprises the steps: detecting a defect along the subsea pipeline using a subsea magnetometric tomography method (MTM) module adjacent the subsea pipeline; and determining a position of the subsea MTM module, thereby determining the position of the defect. The method further comprises determining the position of the subsea MTM module relative to a surface vessel; and determining an absolute position of the surface vessel.
