Echoscope Real-Time 3D Sonar Deployed

  29/04/2008
CodaOctopus Products is delivering Coda Echoscopes for deployment on various underwater construction projects to dredging company Van Oord. Two of three Echoscopes ordered by Van Oord have already been delivered for their Middle East operations.
 

 

In an interesting new application, the systems assist crane operators to correctly position massive 10 ton blocks (Accropodes) on the seabed, 7.5 metres (25 feet) below the surface of the water. In trials, the Coda Echoscope enabled operators to interlock these specialised Accropode blocks significantly faster than conventional technology and with considerably less risk, as it removes the need to use divers to position the concrete blocks. The real-time 3D information provided by the Coda Echoscope allows operators to work with an extremely high level of accuracy based on visualisation to an extremely high resolution.

Hydrographic Survey for Riverbed Erosion

 

U.S. Geological Survey were out on the Missouri River at Williston, North Dakota, USA, performing a hydrographic survey to monitor the state of riverbed erosion. They were using a multibeam echo sounder which transmits sound energy and analyzes the return signal (echo) that has bounced off the riverbed or other objects. Multibeam sonars emit sound waves from directly beneath a ship's hull to produce fan-shaped coverage of the riverbed. 

Gage height at the Williston gage was approximately 27.65 feet when this video was taken. Additional information about the USGS streamgage at Williston is available at http://waterdata.usgs.gov/nd/nwis?program=nwisman&site_no=06330000
