Wärtsilä ELAC SeaBeam 3030

Wärtsilä ELAC SeaBeam 3030 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. Due to its depth performance, wide coverage and multi-ping operation, Wärtsilä ELAC SeaBeam 3030 is the ideal hydrographic sensor for mapping the continental rise.

Wärtsilä ELAC SeaBeam 3030 operates in the 26 kHz frequency band in water depths ranging from 6 metres below the transducers to approx. 7,500 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.
