De Beers Marine Namibia Extends C-Nav Contract
14/10/2008
C & C Technologies (C & C) South Africa has been awarded an extension of the existing C-Nav contract for all mining vessels by De Beers Marine Namibia. C & C South Africa has provided C-Nav positioning to both De Beers Marine Namibia and De Beers South Africa operations since 2004 and has welcomed the extension of services to its offshore mining operations.
With the advent of 3D offshore diamond mining, C-Nav will be supplying De Beers Marine Namibia with precision tools to mine subsurface diamondiferous deposits to centimeter level with full equipment redundancy and signal backup.
Members of the US Geological Survey were filmed while 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 analyses 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.
