C & C Technologies Builds C-Surveyor II™ AUV

November 17, 2004

C & C Technologies, Inc. (Lafayette, Louisiana, USA), recently ordered critical components from Kongsberg Maritime to construct its second Surveyor Class autonomous underwater vehicle (AUV). The C-Surveyor II™ is expected to be available for hydrographic surveys starting in April 2005.

The design of the C-Surveyor II™ AUV will be modeled after C & C's existing state-of-the-art AUV, C-Surveyor I™. Sensors will include a multibeam echosounder, chirp side scan sonar, chirp sub-bottom profiler and a CTD system. The AUV will be positioned using ultra short baseline acoustics integrated with inertial measuring unit and a Doppler velocity log. A fuel cell will provide 45 kWh of energy resulting in an endurance of 50 hours at 3.8 knots with all sensors operating.An acoustic data link will allow sub-sampled sonar data to be viewed in real time. The C-Surveyor II™ AUV will be initially rated for 3000 meters, but will be upgraded to 4500 meters in the fall of 2005.

“Our clients have requested our AUV expertise in several regions of the world," said Thomas Chance, President of C & C Technologies, Inc. “The C-Surveyor II™ AUV will enable C & C to more effectively service the needs of our clients, while decreasing mobilization costs on international projects." C & C's uptime during AUV surveys has gone from 16 percent in 2000 to over 95 percent today. “This success is mainly due to C & C's proprietary hardware and software improvements, C & C's highly detailed procedures, and C & C's experienced AUV personnel," said Chance.

Today, C & C is the undisputed worldwide leader in commercial deepwater AUV operations with market share in excess of 90 percent. Over the last four years, C & C has completed 68 AUV projects in 4 continents for 33 different clients. “The C-Surveyor I™ AUV has surveyed more than 36,000 line-km worldwide. From another perspective, this is the distance between New York and Los Angeles times eight! Imagine going that distance at 3.8 knots!" said Chance. By the end of 2004, C & C hopes to have gone 40,000km, far enough to encircle the globe.

C & C Technologies provides a variety of survey services including Globally-corrected GPS services, marine construction surveys, high-resolution geophysical surveys, geotechnical laboratory testing and land surveys.
