Suitable designed Seabed mapping system.
Bathymetric Data Acquisition
Nudhum has a long track record of collecting bathymetric data, using the latest Multi-Beam Echo Sounders (MBES), whether it be ROV-based or over-the-side pole-based systems. Offshore applications such as trenching (pre-cut, pre-lay, post-lay and intermediate surveys), dredging (pre, post and real-time surveys), sonar/acoustic pipeline inspection, site surveys, or any requirement for a map of the seabed, can be supported with a suitably designed mapping system.
Using versatile, flexible sensors and software we can provide customers with specialised system set-ups, covering everything from vessel navigation systems, subsea positioning, ROV instrumentation, digital video recording systems, tidal corrections and time synchronisation needed to gather high quality data.
Services
Several of the supporting services provides are common to many project types. For accurate vessel and subsea positioning, a well calibrated vessel survey gyro and USBL system is essential. The experienced personnel provide a range of well-established and proven services to complement our other services: These general services include:
- Quayside vessel gyro and motion sensor calibrations
- USBL calibrations
- Dimension control surveys, including offset measurements
- DGPS verifications
- Reporting (data processing and reporting)
- Geodetic consultancy
- CAD and GIS
- Video reording for documentation
