A new fast and accurate AUV based pipeline inspection methodology has been developed. Passive electromagnetic, optic, and acoustic data are continuously and simultaneously acquired along the pipeline and is processed together to get the best awareness of the cathodic protection status as well as potential damages, burial depth, and free span. The acquisition is performed 5-8 m above the pipeline at a speed of 3-4 knots.
