Sloping Float Breakwater: Interim Data Summary.
Abstract
The sloping float breakwater consists of a row of bargelike pontoons moored so that, at rest, the shoreward ends, which are ballasted, rest on the seafloor while the seaward ends, which are buoyant, project slightly above the water surface. Ammi barges and NL pontoon structures have been proposed as breakwater modules. The findings of all previously reported experiments and studies of this concept are brought together to provide an interim summary of data on wave attenuation, mooring forces, ocean transport, and installation. The sloping float concept has potential as a ship-transportable breakwater for relatively shallow water (coastal waters). Floats 90 feet long located in 30 feet of water reduce by about 50 per cent the significant wave height of local-wind-generated waves (Pierson-Moskowitz spectrum) with a dominant (spectral peak) period of 7 seconds.
