The SubSea Quiter membrane base is a technical fabric, which is made up of different types of materials woven overlaid with a coating mixture of elastomer materials and a waterproof sealing foil.
Each SubSea Quieter panel is filled with air that can emptied or filled to manage coastal works activity phases, tidal range, currents and storms and allow vessel traffic.
The SubSea Quieter production method and operating principle have been protected by two patents.
