Deep Water Multibeam System

Elac SeaBeam 3050

Apart from bathymetric data for sea charts, the SeaBeam 3050 multibem system also registers side scan data for more detailed object identification and bottom classification (for instance sand ripple or rocky areas).

For analysis of the water column, water column data are used (water column imaging). They allow depiction of objects not only lying on the seafloor but floating in the water column (plankton, fish schools, according to distance and size). Further information about sea floor structure can be gained by the calibrated back scatter values.

SeaBeam 3050 is fully real-time compensated for roll, pitch and yaw and allows a continuous full coverage, a second journey for filling of gaps is therefore not necessary. The dual ping generates two full swaths during one transmission cycle, this also saves costs, since it doubles the maximum speed up to 12 knots, at a 140° swath with 1 x 1° resolution.

Data density increases due to the dual ping, smaller objects are detected more often and can therefore interpreted as data rather than as measuring errors. Due to its frequency of 50 kHz, the SeaBeam 3050 is the ideal tool for mapping of the continental shelf. It offers excellent depth and coverage (up to 3000 m depth and 4000 m seafloor coverage). High resolution data can be used for detection of gas bubbles in gas hydrate fields.

Elac SeaBeam 3030

SeaBeam 3030 is a version of SeaBeam 3050 offering the same characteristics with modified transmission frequency. Its frequency makes the SeaBeam 3030 the ideal tool for sea floor charting.

  • 30 kHz frequency
  • Multi-ping 630 individual beams
  • 140° swath width with planar array
  • 157° swath width with V-shaped array
  • 7000 m maximal depth
  • Up to 7000 m seafloor coverage
  • Water column imaging
  • Real time motion compensation
  • Shallow water focusing
  • Optional ice-resistant arrays

Elac Seabeam 3012

SeaBeam 3012 multibeam echo sounder collects bathymetric and side scan data in deep sea over a wide swath of up to 140 degrees. The system is fully real time motion-compensated to guarantee full coverage even under severe environmental conditions.

The implemented swept beam technology is superior to any other real time compensation technology in the market to date. The SeaBeam 3012 system offers a depth performance of 11000 m with 110° coverage, resulting in a seafloor coverage of 31000 m (31 km).

The optional water column imaging (WCI) displays real time images of the water column below and to the sides of the vessel.

  • 12 kHz frequency
  • 205 individual beams
  • 140° swath width
  • 11000 m maximal depth (full ocean depth)
  • Up to 31000 m seafloor coverage
  • Real-time water column imaging
  • Real time motion compensation
  • Shallow water focusing
  • Optional ice-resistant arrays

 

 

 

 

 

Elac SeaBeam 3020

Like the SeaBeam 3012 system, the SeaBeam 3020 multibeam echo sounder collects bathymetric and side scan data in deep sea over a wide swath of up to 140 degrees. It is a full-fledged deep sea echo sounder, providing excellent bathymetric, corrected backscatter and side scan data due to its low frequency.

The system is fully real time motion-compensated to guarantee full coverage even under severe environmental conditions. The implemented swept beam technology is superior to any other real time compensation technology in the market to date. Only SeaBeam 3020 offers the full band width and therefore high resolution data at real-time compensation.

A compromise between real-time compensation and band width is not necessary. The SeaBeam 3020 system offers a depth performance of up to 8000 m. The optional water column imaging (WCI) displays real time images of the water column below and to the sides of the vessel.

  • 20 kHz frequency
  • 205 individual beams
  • 140° swath width (130° with ice-resistant transducers)
  • 8000 m maximal depth
  • Up to 10.000 m seafloor coverage
  • Real-time water column imaging
  • Real time motion compensation
  • Shallow water focusing
  • Optional ice-resistant arrays
