Brennan uses advanced hydrographic survey technology to give owners and operators a complete, data-driven view of their underwater assets and surrounding benthic zones. By integrating bathymetric data with above-water imaging, we create precise 3D models that support planning, inspection, and long-term maintenance. These insights empower clients to make informed decisions, minimize risk, and streamline future operations.
Multi Beam Surveys
- Capture dense, high-resolution data for precise 3D models
- Create fly-through tours for exploring underwater conditions
- Identify areas of concern and classify submerged objects
- Support building information modeling (BIM) integration and volumetric analysis for scour monitoring
Single-Beam Surveys
- Effective in shallow-water conditions
- Provide accurate general depth information across a body of water
- Mounted on Brennan’s ROVs for access to confined or restricted areas
Terrestrial Lidar & Photogrammetry
- Generate accurate point cloud images above the waterline
- Combine with bathymetric data for a full structure model
- Enable detailed assessments of infrastructure from top to bottom
