Sustainable, low cost, and effective: NETICS proposes a floating breakwater. Breakwaters protect coastal areas, harbours and waterways against waves and currents. Conventional breakwaters come in two types. The first consists of stacked rubble with a protective cover made of heavy blocks or special elements. This breakwater can often be quite expensive, as an increase in depth will lead to a quadratic increase in cost. Alternatively, caisson breakwaters can be used. They, too, are expensive as they consist of sunken concrete containers which need very strong foundations to keep them from subsiding. We propose a floating breakwater, which uses anchors to stay in place whilst breaking waves. To further reduce costs and increase sustainability, we have developed a breakwater built from recycled materials. We are currently looking for projects which would benefit from this innovation.
