Large breakwaters are frequently built with used barges, ballasted to the desired draft with sand or rock.įloating breakwaters are most effective for wave damping when their width W is of order of half the wavelength L. Accurate design is necessarily based on the combination of numerical and physical models. The forces induced by the mooring system and the connections between the modules complicate the interactions. The performance of a floating breakwater depends on the strongly non-linear interaction of the incident wave (that may partially overtop the module and is in general short-crested and oblique) with the structure dynamics. The modular assemblage and the mooring system are primary points of concern for this kind of structures. In the latter case the efficiency is higher, but the forces between modules are higher. Connections are either flexible, allowing preferably only the roll along the breakwater axis, or pre- or post-tensioned, to make them act as a single unit. The first three types have been more widely investigated by means of physical models and prototype experience than the last one.įloating breakwaters often consist of several interconnected modules. Breakwater layout: Floating breakwaters can usually be rearranged into a new layout with minimum effort.įloating breakwaters are commonly divided into four general categories :įor each category, some types of floating breakwaters are shown in Figures 1 - 5. ![]() Visual impact: Floating breakwaters have a low profile and present a minimum intrusion on the horizon, particularly for areas with high tide ranges. ![]() They may be suitable for areas where summer anchorage or moorage is required.
