Wärtsilä ELAC SeaBeam 3050

Wärtsilä ELAC SeaBeam 3050 is the latest generation medium-depth multibeam system from Wärtsilä, collecting real-time bathymetric data, bottom amplitudes, side scan data and water column imaging (WCI) data in medium water depths. Due to its depth performance, wide coverage and multi-ping operation, Wärtsilä ELAC SeaBeam 3050 is the ideal hydrographic sensor for mapping the continental slope.

Wärtsilä ELAC SeaBeam 3050 operates in the 50 kHz frequency band in water depths ranging from 5 metres below the transducers to approx. 3,500 metres. It has an across-ship swath width of up to 5.5 times of water depth and provides a maximum of 918 beams for each multi-ping. The depth accuracy of the sonar sensor exceeds the IHO (International Hydrographic Organization) requirements.
