HYDROTECHNIK LÜBECK brings environmental protection and technical progress into harmony. The Big Bubble Barrier was developed for offshore wind farm construction sites – a compressed air system that can be used flexibly to reduce noise emissions during pile driving and protect all marine life forms during ammunition clearance underwater blasting. Special nozzle hoses and hose winches have been developed for this work at sea. Experienced teams are now working around the world for environmental protection. In Germany, this development is considered to be “state of the art.” In addition to oil barriers, compressed air barriers, ice prevention systems, and the creation of complete protective systems for seawater desalination systems, underwater noise protection is our most important task.
