SEALENCE · Sub Sea Quieter, a disruptive, low cost and highly efficient Noise Mitigation System for reducing MRE installation noise and turbidity impacts on underwater ecosystems

For offshore windfarms or coastal foundations, pile driving technique is often used. But it generates a high level of noise, which severly damages - up to death - marine mammals, fishes and other species. Noise Mitigation Systems (NMS) exist but with limits : high price, weak acoustic efficiency, bad behavior with current, waves and depth...To fill these gaps, we develop an innovative and eco-designed NMS : the SSQ® Pile Driving.It is based on the disruptive membrane Sub Sea Quieter® (inflatable panels of 3D-woven fabric, coated and sealed to insure acoustic efficiency) resulting from 5 years of R&D.Designed like a sock deployed closest and around the pile thanks to a clever manutention system, it aims at becoming the NMS technical reference by its very high acoustic mitigation efficiency, turbidity containment, its cost up to 5 to 10 times cheaper than existing NMS, with no any extra vessel or crane and its adaptability to the most severe site conditions (waves, curent, depth...).
