Study on Hydrodynamic Response of Parallel Berthing Structures
Floating structures berth with one another are quite close when offloading at sea,creating a narrow domain between them.Fluid dynamics and coupled motion of floating may be stimulated by external loads,causing challenges to offloading.In this paper,for the plan of barge unloading on bottom-sitting platforms in shallow waters,the hydrodynamic interference between parallel berthing boats is evaluated.The berthing vessel's mooring system is designed,and the hydrodynamic response is analyzed in time-domain.The platform's stability and anti-slip performance as well as the floating body's motion reaction are also considered.The results demonstrate that the mooring system can successfully restrict the structure's relative motion within a given range,and that both the tension value of the mooring rope and the force of the fender are within the permitted range.In order to acquire horizontal anti-slip capability,the bottom-sitting platform must be subjected to significant horizontal thrust and require significant ballast to enhance its wet weight.These works serve as a reference for the platform's mooring design and hydrodynamic analysis in shallow waters.
