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

Introduction

For offshore wind farms or coastal foundations, pile driving technique is often used. However, it generates a high level of noise, which severely damages—up to death—marine mammals, fishes, and other species.

Noise Mitigation Systems

Noise Mitigation Systems (NMS) exist but come with limitations:

• High price
• Weak acoustic efficiency
• Poor performance in currents, waves, and varying depths

Innovative Solution

To fill these gaps, we develop an innovative and eco-designed NMS: the SSQ Pile Driving.

Technology Overview

It is based on the disruptive membrane Sub Sea Quieter, which consists of inflatable panels made of 3D-woven fabric, coated and sealed to ensure acoustic efficiency. This technology is the result of 5 years of R&D.

Design and Functionality

Designed like a sock, the SSQ Pile Driving is deployed closest to and around the pile thanks to a clever manipulation system.

Key Benefits

It aims to become the NMS technical reference due to:

1. Very high acoustic mitigation efficiency
2. Turbidity containment
3. Cost-effectiveness—up to 5 to 10 times cheaper than existing NMS
4. No need for extra vessels or cranes
5. Adaptability to the most severe site conditions (waves, currents, depth)
