Advanced technical power
The only submersible remotely operated vehicle capable of operating at depth or altitude from a moving surface platform.
Inventors Marc and Krist Geriene spent over seven years engineering this technology to solve the problem that had limited the industry for decades: cable drag in strong currents. The Treasure Experience holds exclusive rights to deploy the patented platform.
The breakthrough
A flat-wing or open-frame vehicle on a tether is dragged sideways by current, and the umbilical itself generates lift that pulls the vehicle off station. Operators compensate with more cable, more weight and more power, and still lose the ability to hold a line in a cross-current. Flat wings also develop Dutch Roll Instability, a rolling oscillation that makes stable survey flight impossible.
The Nova Ray's arcuate, bow-shaped wing eliminates Dutch Roll Instability entirely and lets the vehicle hold stable axis flight in current. Rather than resisting flow, the platform effectively uses water flow rather than resistance to maintain operational control, counteracting the lifting force of the umbilical as it goes.
The platform
Bow-shaped rather than flat. That single decision removes Dutch Roll Instability, counteracts the lift the umbilical generates, and lets the vehicle hold a line while the surface platform is still making way.
Capabilities
The arcuate wing geometry eliminates the Dutch Roll Instability inherent to flat-wing designs, holding attitude in turbulent and cross-current conditions.
The wing works against the lifting force generated by the tether, so the vehicle stays on station instead of being pulled up and off target.
Because the platform flies rather than hangs, it reaches working depth on substantially less umbilical than a conventional ROV requires.
Functions effectively under its own thruster power and in tow mode behind a moving surface platform, which is the capability nothing else on the market has.
Thrusters sit close to the control surfaces, giving a short moment arm and precise handling around a wreck site.
Designed for real survey conditions rather than flat-calm test tanks: turbulence, cross-currents, and a vessel that is still making way.
