Buoys equipped with acoustic recorders are used to evaluate the level of noise on wind farms in Germany. Calculation in real time, proposed by RTsys, has been very successful.

A species of porpoise endemic to the German coast is very sensitive to sound waves, because this species mainly uses its hearing to position itself. In order to avoid disturbing its natural habitat, German legislation imposes a maximum sound level that must not be exceeded, especially in offshore wind farms.

Since 2014, RTsys has been providing buoys equipped with acoustic recorders, which analyze data in real time. These buoys are based on underwater acoustic recommendations and standards. Thanks to this way of working, innovative technology developed by RTsys is now recognized and authorized by German authorities. Users on offshore wind farms therefore have a tool to manage construction work, enabling them to make quick and reliable decisions.

Three years after the initial tests were carried out, RTsys acoustic buoys are now used on many offshore wind farms throughout North West Europe. Within the context of renewable marine energy development, the reliability of its products and real-time monitoring has been very successful.

RTsys, innovation in underwater acoustics and drones

Specialists in passive and active underwater acoustics and drones, the RTsys company has more than 30 years of expertise and extensive business experience in the development of reasonably-priced high-tech products. Its innovations are used not only in the civil sector, but also for defense, and are equipped with SDA (Synchronous Data Acquisition) technology, developed by RTsys.

Within a context of increased monitoring of the marine environment, in connection with reducing noise pollution, RTsys is one of the front-runners in acoustic monitoring, following huge investment in research and development, and in cooperation with the scientific community.

RTsys' recognized expertise in the defense sector and its close collaboration with the French Navy enable it to develop innovative underwater detection tools and drones for use in anti-submarine warfare.

Notable recent RTsys achievements include underwater drones, which can communicate as a pack and the MIMO (multiple input multiple output) acoustic modem, which considerably increases the data transfer rate in water.
