Study On Hydronamic And Dynamic Analysis For Mooring System Of Aquaculture Unit

With the continuous development of marine aquaculture,the market demand for aquaculture platform is growing.The optimal design of mooring system is the difficulty in the design of aquaculture platform,so it is of great practical significance to analyze the hydrodynamic force of aquaculture platform and summarize its laws.The mooring of deep-sea aquaculture platform can be divided into tension mooring and catenary mooring.At present,the research shows that for large-scale deep-sea aquaculture platform,tension mooring is generally used.At present,there is no relevant standard reference for the aquaculture platform,and there is little research on the aquaculture platform.This paper analyzes the hydrodynamic performance of aquaculture platform and summarizes its motion response and the change of mooring force of cable This article mainly includes the following contents:1.The Aqwa Hydrodynamic Diffraction module is used to analyze the frequency domain of the given wave direction of the aquaculture platform,and the motion response amplitude operator(RAO)is obtained,and the analysis is carried out to summarize the motion law of the aquaculture platform,so as to provide preparation for the later time domain analysis.2.The Aqwa Hydrodynamic Response module is used to analyze the mooring of the aquaculture platform in time domain.The results of the analysis of the dynamic response of the platform,such as the sway,surge,heave,roll,pitch and yaw,as well as the mooring force of the linear cable,are obtained,which provides the preparation for the later optimization and improvement.3.According to the results of time-domain analysis,appropriate measures are sought to optimize and improve the motion response and mooring force of the aquaculture platform,and methods and rules are summarized to improve the mooring performance of the aquaculture platform,which is used to guide the design of the mooring system of the aquaculture platform.
