Unmanned Semi-Submersible Trial20/05/2009 |
| C & C Technologies is set to sea-trial its new Unmanned Semi-Submersible (USS) this June in the Gulf of Mexico. The 6-metre vehicle was designed and built over the last three years as a substitute for the standard hydrographic survey launch. Powered by a 30 horsepower diesel engine, the vehicle will be suitable for large nautical charting surveys and mine defence efforts. |

The USS operates just below the water's surface with a mast extending above the waterline. Payload sensors include a keel-mounted side scan sonar, multibeam echosounder, and CTD. The mast includes a video camera, C-Nav DGPS, and wireless antenna for high-speed telemetry of data.
Like an AUV, the vehicle will be able to operate autonomously in a wide range of sea conditions, yet with the exposed mast, data can be reliably positioned with DGPS and relayed back in real time. Unlike an AUV or a launch, the USS will be able to operate for four days at four knots, or two days at eight knots.
Through a contract with the U.S. Naval Research Laboratory, C & C engineers have designed the system for multiple unit deployment and payload flexibility. The company intends to build additional vehicles for use worldwide through survey service contracts or system sales.

Hydrographic Survey of Riverbed Erosion |
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.
