【Abstract】 This paper deals with the procedure of predicting the performance of multi-mooring floating breakwater in regular waces, which includes the motions of breakwater, transmission coefficient,steady displacement of breakwater and mooring line tension caused by steady drifting force, and goes a step further to predict the wave reducing performance of floating breakwater in irregular waves. Frank’s closed -fit method, Grim’s strip method, Maruo’s formula of far field method for two-dimentional drifting force, Kim’s method for the amplitudes of reflected waves at infinity and the classical catenary theory of mooring lines are used. Numerical results ane compared with Inoue’s calculation on rectangular vessels and model tests on a trectangular breakwater undertaken by Nanjing Water Conservancy Science Institute and good agreement is found. The aim of this research is to monitor the performance of floating breakwater and to optimize the configuration of floating breakwater using theoretical model. The theoretical model,combined with model tests is applied successfully in the design of a floating guiding breakwater in famous Three Gorge Reservoir which is being built in China.更多还原
