<p>A lattice structure is mounted on one or more buoyant units turned towards approaching waves. It is used in a breakwater for floating stages in harbour installations. This is made up from lattice bars set at a lateral interval part, and vertically close together in the vertical plane projection. Their ends are interconnected by two horizontal rails. It is divided into two sections at an angle. The lower section slopes down, and is partly below the water surface. This is simple and light, but adequate on its own in lakes or relatively calm coastal waters.</p> |
