PanGeo Subsea recently deployed the SBI frame from dockside crane and conducted a series of SBI sweeps in the target area and successfully imaged a UXO buried in 6m of silt in 8m water depth. The UXO was successfully recovered.
Previous attempt by others using traditional SBP and Magnetometers failed to detect the UXO.
