High-Precision Long-Term Submarine Metocean Monitoring

Seabed Observation System: BA-SUBSEA-NX2

Seabed Observation System is a highly integrated, autonomous, bottom-mounted platform engineered for long-term metocean monitoring in coastal and continental shelf waters. Designed with a priority on data quality and asset security, it delivers reliable hydrodynamic and wave measurements—including current profiles, directional waves, tide, temperature, and salinity—while keeping your offshore maintenance costs to a minimum.

Applications:

  • Offshore Wind Site Assessment & EIA 

  • Coastal & Marine Research 

  • Subsea Infrastructure Monitoring (UDC, cables, pipelines) 

  • Port & Coastal Engineering Projects

  • Marine meteorological monitoring & forecasting

Multi-Parameter Integration

  • Synchronized data: currents, waves, tide, temp, & salinity. 

  • Industry-proven high-stability sensors. 

  • UV anti-fouling mechanisms ensure long-term data quality. 

  • Low-profile stable frame minimizes attitude errors.

Full-Link Redundancy & Safety

  • Dual independent SD cards for zero data loss. 

  • Dual primary battery banks to prevent power failure. 

  • Dual acoustic releases ensure safe equipment recovery. 

  • 316 stainless steel frame & 5-ton anchor resist trawling.

400+ Days Endurance

  • Ultra-low power consumption architecture. 

  • Covers complete seasonal variations with a single deployment. 

  • Significantly reduces costly service vessel visits.

Near Real-Time Management

  • Standard acoustic comms for contactless data retrieval. 

  • Optional surface buoy for daily data transmission. 

  • Hourly device health monitoring (voltage, tilt, etc.) via buoy gateway.
