N-Sea Develops UXO Detection System
Subsea IMR provider N-Sea has launched Magsense, a vertical gradiometer array specifically designed for highly accurate Unexploded Ordnance (UXO) campaigns.
Developed in-house by N-Sea, the system has been designed to collect and record high resolution data in magnetically noisy subsea environments and hostile conditions, delivering improved accuracy, efficiency and safety in the detection of UXO.
“Specifically designed for wide seabed survey, with highly accurate UXO target detection and accurate modeling, [Magsense] is suitable for use in all environments,” said N-Sea Chief Operating Officer, Roddy James. “Uniquely, this allows for the collection of high quality, high density gradiometer data in previously inaccessible, shallow tidal areas.”
Used in conjunction with a remotely operated tow vehicle (ROTV), the MagSense frame can be towed through the water in ways previously not feasible, ensuring even the most uneven of terrain is tracked accurately and consistently, N-Sea said. Additional sensors provide a better control of the unit, and the 3D steering of the frame drastically decreases the amount of infill to be budgeted for, while its specially-designed launch-and-recovery system keeps manual handling to a minimum and reduces risk to personnel.
