A solution that is now operational was developed by RTsys for the Monaco land extension project, which is located between a nature reserve and a protected area, where six hectares will be reclaimed from the sea to extend the principality of Monaco. The project’s environmental impact is being closely monitored and requires constant surveillance. Tracking the impact of a construction site at sea in real-time requires a process including data collection, processing and display.

RTsys underwater technologies installed at the site are used to collect, analyze and transmit real-time acoustic, physico-chemical and visual data, which will be used to protect marine mammals, including some that are protected species, during the project. These indicators allow the site manager to control the impact on the local environment. At the site, hydrophones paired with physico-chemical probes have been immersed along the perimeter to give greater precision on the observed parameters: hydrophones continually log sound waves while probes measure temperature, oxygen levels in the water, as well as turbidity, salinity and depth. The sensors mounted on probes are specifically adapted for the site conditions and equipped with a wiper to face highly turbid conditions. All acoustic and chemical data collected are then transferred to the Resonance cloud by Ethernet cabling, 4G, iridium or UHF radio waves.

The Resonance web interface for real-time tracking displays data captured by the installed equipment in a centralized interface. Developed by RTsys engineers to meet strict specifications, it is now operational on-site and is even being used in other contexts. Data stored on dedicated servers then generate reports allowing day-to-day tracking. —RTsys
