Abstract
Summary
For decades, the methods of surveying for subsea hazards including pUXO has not changed. This leads to extensive multi-phase surveying, identification and clearance (ID&C) campaigns, higher costs, program delays, and increases project uncertainty for operators and developers. Although survey is a relatively small phase of the overall development, these data outputs underpin some of the larger cost items.
Commercially viable 3D acoustic technology is now viable and combining datasets allows for significant reduction in false positives during pUXO survey campaigns, proper determination of target depth and identification of a range of targets of interest, as well as non-ferrous UXO. This new method of surveying is not only beneficial for the direct validation of magnetometer targets and pUXO risk mitigation, but for simultaneous acquisition of geological and shallow hazard information for ground models and burial risk assessments. The current phased approach to site investigations has never been more open to interpretation.
