Nearshore Survey AS has specialized on high resolution seabed mapping in coastal waters, lakes and watercourses. In addition to modern surveying methodology, we have optimized equipment and methods to operate safely and efficiently at challenging places such as close to the shoreline, in areas with limited depth, in rivers or tidal streams and in remote areas where equipment and personnel must be by transported by special vehicle or helicopter.
Mapping of detailed bathymetry for volume calculations, evaluation of cable routes, road construction or study of geology/geo-hazards.
Scanning of dam/dam wall and adjacent areas. Optionally combined with laser data for "seamless" 3D-surface.
Bathymetric survey to document navigable depth, sediment transport or development of nearby infrastructure.
Multibeam survey and ROV-inspection of cable corridors for route engineering and calculation of cable lengths.
Surveys adapted to the various phases from early site assessment to micro siting and installation of fixed or floating foundations.
Hydrographic surveying, monitoring and documentation during dredging operations in accordance with IHO S-44 Edition 6.0.0
Surface positioning service (RTK GNSS) and underwater navigation (USBL), in real time or over a periode of time.
Installation of sensors and systems for logging and near real-time presentation. Example: www.waterlevel.no
