| The ocean space is vast and the resources are very rich,and human beings have conducted many research on how to use marine resources,including the two fields of the wind turbine platform and cage farming.The hotspots of many scholars at home and abroad.At present,offshore wind turbine platforms are mostly fixed platforms and are mostly installed in offshore waters.However,offshore wind energy resources are limited,and offshore fixed wind turbine platforms can no longer meet human energy needs.However,as the offshore area is limited and with the further development of marine resources,the aquaculture space in offshore areas is getting smaller and smaller,the aquaculture density has risen sharply,and the aquaculture density continues to increase.The aquaculture industry also urgently needs to develop into the deep sea field.In view of the above problems,combining the offshore wind turbine platform with the cage aquaculture platform to research and develop a stable,efficient,economical,and reusable integrated platform for wind power fishing grounds has good prospects.Therefore,it is of far-reaching significance to carry out related hydrodynamic performance research.This paper reviews the research status of the domestic and foreign sea wind power platform and the architecture,Summarize the calculation theory of wave load,wind load and current load,introduces the calculation method of frequency domain and time domain of semi-submersible platform.According to the basic information of the 5MW wind turbine,the comprehensive platform model is designed and built from the safety of the wind power fishery integrated platform,and the processes and results are as follows:First,in ANSYS WORKBENCH,The small-scale component structure and the large-scale panel structure were established by using Morrison unit and surface unit,which established a finite element model.Based on the Morrison equation and the three-dimensional flow theory,the integrated platform is used to calculate the integrated platform,and the additional damping,RAOs and other parameters are obtained by using marine engineering floating body analysis software AQWA.The results show that all the different rollover directions and different water depths will have an impact on the frequency domain of the integrated platform,and the integrated platform has a high frequency region response to the frequency higher than 0.3 Hz,and less than 0.3 Hz.The low frequency area response is remarkable.Secondly,with the Numerical simulation software FAST,the wind load of the platform is calculated,which will be loaded in the integrated platform.Time domain analysis of the integrated platform under the combined action of wind,wave and current.Mainly analyze the platform mooring system and time domain lane response curves to study the safety of the comprehensive platform in the marine environment.The effects of analysis of platform mooring resistance by analyzing the tension of the tension,mooring tension,mooring arrangement angles.Different mooring parameters have different degrees of impact on mooring system,and finally,the platform mooring system program is optimized,and the mooring performance is improved,and the mooring requirements are met.By analyzing the time domain motion response of the integrated platform,you can learn a significant impact on the different waves in different waves,and this effect is even more in the platform.It is obvious.Therefore,when designing semi-submersible platforms,the safety needs of semi-submersible platforms are met due to comprehensively considering their own structures,mooring cables,and environment.The wind power fisheries integrated platform designed in this paper has strong ability to resist wind and waves,which can produce safely in the designed sea conditions.The motion response value can meet the requirements of the specification,indicating that the wind power fishery comprehensive platform designed in this paper is reasonable. |
