Introducing Argeo Listen
Argeo Listen is a passive electrode-and magnetometer system for electric-and magnetic field measurements in sea water. The system is modular and can be implemented into various underwater vehicles.
Currently the system is fully integrated on Argeo’s AUV platforms which can operate down to 6000m water depth.
Argeo Listen is perfect for inspection of subsea cathodic protection systems, positioning of buried power cables, marine mineral exploration and general site surveys.

Cathodic Protection
Zinc sacrificial anodes are used to protect pipelines and subsea installations from corrosion. The anodes corrode in stead of the pipeline and needs to be replaced from time to time. By flying Argeo’s AUV over the pipe Argeo Listen measures and identifies the condition of these anodes from the strength of the electromagnetic field. The measurements can be used to determine the need for replacement.
Cable Inspection and positioning
By flying Argeo’s AUV over the seafloor Argeo Listen can localize electrical cables that have been buried or exposed by shifting sand dunes on the seabed. The tool pinpoints the cable’s position including burial depth, in real time. Repeated surveys can be used to predict future trends in cable positioning movements and changes in burial depths.
