Three SeaBat sonar systems delivered to Germany
RESON awarded contracts for the delivery of three SeaBat multibeam sonar systems for hydrographic and research applications.
An ultra-high resolution 400kHz SeaBat 7125-SV multibeam sonar system together with PDS2000 data acquisition and processing software, and a SVP70 sound velocity probe, has been delivered to Forschungszentrum Küste (FZK), Hannover.
The sonar system will be used for research in the large wave flume (GWK), where it will observe changes on the seabed under different wave conditions with wave heights of up to 2,5m. With dimensions of about 300 m length, 5 m width and 7 m depth GWK is the largest experimental facility of its kind worldwide.
One unit of the new SeaBat 7101 multibeam sonar system together with SVP 70 and SVP 14 were delivered to the Hamburg Port Authority. Hamburg port is one of the world’s most productive ports with more than 40 km of quay wall.
The sonar will be used for general bathymetric measurements in the harbor.
Another SeaBat 7101 also together with a SVP 70 and SVP14 have been delivered to the head quarter of GeoIngenieurservice Nord Ost GmbH in Miltzow. The company offers various hydrographical services for which it will use the SeaBat 7101.
The SeaBat 7125-SV has an effective swath width of 128°, up to 512 beams and a fast ping rate. It is typically used for a variety of offshore and hydrographic applications as well as marine research.
The SeaBat 7101 measures discrete depths over a wide, 150° swath to a maximum range of 500m while operating at 240kHz. A true, time-delay beamformer uses a combination of amplitude and phase detect for maximum performance across the entire swath.
Roll stabilization maximizes efficiency during survey operations. Dense sounding coverage is achieved with a combination of 240 equi-distant beams and a range-dependent ping rate of up to 40Hz.
