Multi-Module Coupling Dynamic Response Analysis of Ultra-Long Scale Floating Breakwater
In order to study the coupled dynamic response law of multi-module floating breakwater modules,based on the environmental conditions of the target sea area,A general layout design scheme of ultra-long scale floating breakwater that can provide ultra-large cover waters is proposed,and the configuration,connection structure and mooring system of ultra-long scale floating breakwater is designed.On this basis,based on the three-dimensional potential flow theory,the frequency domain and time domain analysis of the hydrodynamic performance of the ultra-long scale floating breakwater are carried out,considering the multi-module coupling motion of the floating breakwater under environmental load,and the motion response of the modules and the mooring cable tension are compared.The results show that the motion of the middle module of the ultra-long scale floating breakwater is the most intense in heave,roll and pitch direction under the conditions of transverse and inclined waves.Because the head module of a floating breakwater has the most violent rolling motion under the conditions of transverse wave and inclined wave,the mooring line of the floating breakwater head module is subjected to the greatest tension under the two conditions,which should be paid attention to during the design of the mooring system of a super-long scale floating breakwater.The numerical simulation results can provide technical support for the design and engineering application of ultra-long scale floating breakwater.
