Bathymetry consists of using sonar to conduct a 3D survey of a submerged element. For Can-Explore, this method is a first key step in investigating a submerged structure. The information collected allows the team to focus on areas of interest where detailed additional inspection must be done. The 3D model helps, among other things, identify the following types of defects:
- Scouring under wharfs;
- Major structural deformation;
- Large holes or anomalies.
