NuShuttle - Towed, undulating, data gathering platform for oceanographic monitoring

NuShuttle - Towed, undulating, data gathering platform for oceanographic monitoring Chelsea Technologies Group’s NuShuttle is a proven, low cost and robust towed undulating vehicle in use on ships of opportunity and research vessels. NuShuttle can be fitted with a wide variety of sensors to provide data on such parameters as conductivity, temperature, depth, chlorophyll, hydrocarbon and Gelbstoff fluorescence, turbidity, optical transmittance, bioluminescence, nutrient, redox and dissolved oxygen.

 

It also has capacity to carry a mechanical Plankton Sampler or an Optical Plankton Counter. NuShuttle can be towed at speeds of 5 to 15 knots to operational depths of >150m. It can be launched and recovered while the vessel is underway, by a non-scientific crew with minimal training.

How does it work

NuShuttle is a stable, very robust, versatile undulating towed vehicle for the deployment of a wide range of oceanographic monitoring equipment. Developed by Chelsea Technologies Group and the Plymouth Marine Laboratory, UK, NuShuttle has been designed to meet the requirements for a low cost, large payload vehicle.  The NuShuttle is controlled by a Servo Unit with on-board pressure sensor for feedback. The Servo Unit is powered by an Impellor, and is mechanically linked to the control fin. The Servo Unit is programmed to instruct the NuShuttle to follow a user set undulation path.

 

The NuShuttle can be configured to operate either autonomously with a non-conductive tow cable, or configured to provide real-time data to the surface via conductive cable. CTG’s NuShuttle can be fitted with a wide variety of sensors to provide data on such parameters as conductivity, temperature, depth, chlorophyll, hydrocarbon and Gelbstoff fluorescence, turbidity, optical transmittance, bioluminescence, nutrient, redox and dissolved oxygen. It also has capacity to carry a mechanical Plankton Sampler or an Optical Plankton Counter.

Support Systems

Winch

Dedicated winch with slip ring assembly only required when used in real-time mode with power/data communication to surface deck unit. When towing on a bare cable, a standard ships capstan may be used.

Cable Rochester 7-H-314A or equivalent for real-time deployments. 
Fairing Flexnose(R) style fairing is used  

In view of our continual improvement, the designs and specifications of our products may vary from those described.
