Preconstruction site survey
For the design of offshore constructions it is necessary to have information regarding the seafloor and subsurface structure, such as bathymetry, side-scan sonar images, seabed classification, magnetic anomalies and subsurface structure and lithology. The Sub-bottom profiler provides valuable information regarding the sub-seafloor structure, gases in sediments and hard bottoms where digging is hard to do. Sediment thickness maps and sediment volume calculations are derived from this type of data.
