Preliminary Results and Promising Performance

The recent visits provided an opportunity to witness the SubSea Quieter® in maritime conditions for the first time. Some results :  

• The system was successfully assembled in just a few days in accordance with operational and safety procedures ; 
• The Subsea Quieter demonstrated its reliability and ease of deployment, with over 150 cycles (deployment/inflation/deflation/recovery) in a few weeks; 
• The system underwent acoustic testing for over 1 week, enabling us to test different configurations and measure the system’s performance over a wide frequency range, including low frequencies with the use of air guns; 
• The system demonstrated its reliability and resistance to current, with good behavior at currents superior of 1m/s. 

While the final results of the acoustic performance tests are forthcoming, initial measurements are already highly promising. The SubSea Quieter® has demonstrated efficacy in reducing underwater noise pollution, highlighting its potential to safeguard marine ecosystems. 

Gratitude and Acknowledgments

We would like to thank all of the individuals, organizations and members of the press who took the time to attend our technology demonstrations and press conference. Your presence and support is invaluable as we continue to innovate and strive for a sustainable future for our oceans. We received a lot of feedback from technical experts, operational advices and recommendations for future demonstrations of our Noise Abatement System in a context of real pile driving operations. 

As the number of offshore wind turbine installations continues to rise, this innovation holds immense significance for the protection of our oceans. Underwater noise generated by construction activities poses a severe threat to marine life, making solutions like the SubSea Quieter® crucial for mitigating these impacts.
