Offshore Renewable and Wind Energy

RTsys technology and equipment are perfectly adapted to offshore marine constructions. Underwater noise recorders and buoys allow the surveillance of sites during offshore structure building as well as adapt the pile-driving intensity while setting up a wind farm offshore. This is also a way to determine how theses activities impact the wildlife around these sites.
