Project - IJmuiden seaport
T&A Survey performed a large-scale UXO waterbottom survey for the construction of a new sealock in IJmuiden, The Netherlands.
Detection in shallow water is often done using a survey boat equipped with several probes on a rack. In deeper waters a so called Fish is used, pulled by a survey boat.The disadvantage of this technology is it’s imprecise positioning and depth measurement. In the seaport of IJmuiden
T&A used an AUV (Autonomous Underwater Vehicle) for detection of UXO. The AUV follows the water bottom and is equipped with a magnetometer probe and Side Scan Sonar. Objects that were suspect according to magnetometer results could be excluded based on Side Scan Sonar results.
