ACSA, a French company that develops undersea robotics and underwater positioning systems, has successfully tested its unmanned underwater vehicle (UUV), SeaExplorer, in the Mediterranean Sea.
The test resulted in SeaExplorer breaking two world records, one of autonomy for multi-sensors UUV with rechargeable batteries and the other for maximum distance covered by multi-sensors UUV with rechargeable batteries.
SeaExplorer moves through the water by changing its buoyancy and collects important ocean data at depths of around 750m.
The glider measures conductivity, temperature, depth, oxygen, hydrocarbons and other real-time data that is useful for various groups, including oceanographers and the military.
The glider moves at a speed of one knot due to its high ballast volume. The vehicle features an independent payload section with two large compartments, a hyperbaric and a wet section, at the front of the vehicle that can be changed easily in between two missions.
The glider is also equipped with pumped CTD, oxygen optode, turbidity, chlorophyll, backscatter CDOM, hydrocarbon fluorescence, acoustic detector and recorder, and other sensors.
A networked hardware and software suite allows the vehicle to be tracked from anywhere in the world via the Internet.
The testing in the Mediterranean Sea was carried out at depths of 500m.
ACSA said the world record highlights the reliability of the SeaExplorer as a proven and cost-effective solution for ocean data collection useful in the oil and gas industry.
