Floating breakwaters can only be used economically in fairly sheltered locations where effective fetch is less than 6 km (i.e. wave period generally of less than 4 seconds).
The breakwaters reduce the wave height and strength by directly deflecting some of the energy and dissipating smaller amounts by friction and turbulence. Significant amounts of energy are dissipated by the movement of the floating breakwater due to its size and flexible anchoring.
The main technical parameters i.e. width, height, weight and moment of inertia, are selected for maximum attenuation capacity. The connection between the pontoon units is semi-flexible with sufficient rigidity to enable the breakwater to work as a continuous structure - a significant advantage in wave attenuation capability.
