Dredging operations demand precise knowledge of both vessel motion and equipment orientation at every stage of the work, from the surface vessel down to the cutting head or draghead on the seabed. Whether operating a Trailing Suction Hopper Dredger, a Cutter Suction Dredger, a grab dredger, or a water injection dredger, accurate real-time motion data is fundamental to dredging accuracy, equipment protection, and operational efficiency.
