Drones, underwater recorders and multi-hydrophone buoys for oil and gas exploration

RTsys helps oil & gas companies to make their prospecting campaigns. The use of airgun is common for oil & gas prospection. This is pretty heavy and we provide these companies tools to determine how the noise generated can affect the marine wildlife.


COMET is a cost-effective operational AUV with real-time positioning and acoustic communication system, designed to meet the current needs of marine research and industry.
COMET can operate alone or in a network with surface buoys or vessel. It is also the first AUV able to operate in homogeneous swarm.
