Survey positioning is conducted using state of the art Differentially-Aided GPS, RTK and PPP solutions to provide centimetre accuracy of seabed features and water depth. DOF Subsea continues to demonstrate the ability to deploy shallow water survey systems on almost any vessel platform and we are specialists in working in low water depths such as inside tidal zones. Our survey techniques can provide high resolution data which exposes features (Green) that would otherwise be hidden in traditional low resolution LIDAR imagery (Blue). DOF Subsea has the ability to produce highly detailed charts to meet the specific needs of the customer including harbour approaches for specific vessel draft clearances. All specifications are subject to changes without prior notice, Please contact us for details and verifications By providing shallow water Geotechnical Survey services, it is possible to provide much higher accuracy data than otherwise commercially available. Remote coastline can be surveyed to a level of detail far higher than through traditional sources such as LIDAR. A DOF ASA COMPANY
