![]() The greater the concavity of the curve, the better the model handles waves, especially when the wave steepness is low. The modular arch-shaped concrete structure is positioned perpendicularly to the direction of the prevailing wave and wind. The curved face model significantly reduced wave transmission values when compared to the traditional vertical configuration. A novel floating breakwater-windbreak structure (floating forest) has been designed for the protection of vulnerable coastal areas from extreme wind and wave loadings during storm conditions. In terms of hydrodynamic performance, the curved-face floating breakwater outperformed the traditional vertical floating breakwater, according to the study's highlights. The incident, reflected, and transmitted wave heights were measured, and the coefficients of reflection, transmission, and energy dissipation were calculated using these measurements. 2012) on the development of optimal shape of a 2D floating breakwater, a genetic algorithm (GA) was adopted and we could obtain an optimized 2D shape. A series of experiments were carried out in the lab of The Higher Institute of Engineering (El-shorouk City) on the new model and the traditional vertical plane FB without a curved face to compare their behaviours and performance in wave attenuation. This study involved the testing of a new floating breakwater configuration (FB). Most current studies and scientific investigations are centered on how to protect seashore with an efficient and cost-effective system. The goal of the optimization problem is to design an optimal floating breakwater that can attenuate the waves to the mini- mum height inside the port and fulfill several constraints related to. TABLE 1.It is critical to protect coastal and offshore structures. Floating breakwaters are used increasingly as a means of protecting small boat marinas in the United States. Table 1 lists some prototype breakwaters with design conditions and costs. The mooring system comprises sets of mooring lines anchored to the seabed. ![]() Periodic maintenance is usually needed to repair damage from fatigue, abrasion, and electrolysis. Preventing mooring line failure is a key design objective for floating breakwater systems. 1487 - 1499 Figure1: Outline of a floating structure in the Model Designer section of ANSYS AQWA software Figure 2: Three-dimensional view of floating breakwater model drawn in ANSYS AQWA software ANSYS AQWA software is capable of analyzing the interaction between. Final design is usually based on model or prototype tests of the proposed breakwater and predicted wave climate. 1490 Bulletin de la Société Royale des Sciences de Liège, Vol. Caution must be used in extrapolating the L/VV parameter for design. Fixed structures are commonly used to shelter port basins and vessels from extreme wave conditions. However, future investigations of larger structures, such as barges, inclined pontoon, and multiple rows of breakwaters, may extend application to longer periods and higher waves. Request PDF Dynamic analysis of floating breakwaters: a case study Abstract. The limiting design wave for single box or pontoon type breakwaters is presently 4 ft high and 4 sec period. The analysis results produced an initial design of floating breakwater structures suitable for waters in the research location based on these environmental variables: wavelength (L) 13.58 meters. Presently, most floating breakwater applications are for short-period wind wave or boat wake protection at semisheltered sites in estuaries, reservoirs, lakes, and rivers. A multiple breakwater layout was model-tested for protection of the Seabrook Lock approach, Lake Pontchartrain, La. BREAKWATER LAYOUTīreakwaters can be arranged as a single line of defense or a series of lines that reduce the wave to acceptable height. Mooring line scope is usually between 3-1 and 5-1 regardless of anchorage type. Lines are used, they should be offset to prevent chafing. 23.-Single Floating Breakwater LayoutįIG. As compared with land-based bridges, only limited information is available for floating bridges in many respects, such as past construction records, meteorological and durability conditions. 18.-Propellant-Emhedded Anchors (After Ref. There are many types of floating bridges, depending on the conditions of the land and the types of barriers to cross.
