In an innovative project named EONIOS, a fleet of autonomous underwater vehicles (AUVs) will be deployed to monitor offshore artificial reefs off the coast of Cyprus. These artificial reefs, constructed using 3D printing technology and an eco-friendly cement mixture, aim to attract marine life to previously barren sections of the sea.
The AUVs, equipped with sensors and high-definition cameras, will provide valuable data to scientists at the Cyprus Marine and Maritime Institute. They will be stationed at docking stations on the artificial reefs, allowing them to recharge and transmit collected data, including video footage.
One of the key advantages of using AUVs is their ability to remain submerged for extended periods, up to a month at a time. This continuous monitoring capability will enable scientists to detect any disturbances in the protected waters, such as illegal fishing activities or encroaching boats, and promptly alert local authorities.
The trial run of the EONIOS project is currently underway near the Ayia Napa marina, with plans to deploy the artificial reefs off the southern coastal town of Limassol at a depth of approximately 20 meters. These reefs are strategically placed to allow sunlight to reach the seabed, creating an ideal environment for marine life to thrive.
The collaboration behind EONIOS involves the Cyprus Marine and Maritime Institute, AUV manufacturers Arkeocean, Cypriot tech company SignalGeneriX, and French consultancy company Lanego. The project aims to market this innovative solution to other countries interested in enhancing their fish stocks through artificial reefs.
Arkeocean's AUVs offer a cost-effective surveillance and data collection solution compared to traditional tethered submersibles. These mini-drones can carry up to 5 kilograms of equipment and operate at depths of up to 300 meters, with plans for future versions to reach depths of 3,000 meters.
With battery-powered thrusters and stealthy operation, the AUVs are ideal for various applications, including defense surveillance in restricted waters. They can navigate using undersea currents to conserve battery life and are equipped with an Iridium satellite antenna for global operation.
Aside from monitoring artificial reefs, these AUVs have potential applications in energy exploration, such as detecting seismic activity for offshore oil and gas exploration, as well as identifying suitable locations for offshore wind and solar farms.
