新型网箱浮架系统水动力分析及系泊方式研究

设计了一种新型网箱浮架系统,利用SESAM对其进行了频域水动力分析以及考虑不规则波浪、风、流载荷和系泊共同作用的时域耦合分析,并与传统双浮管网箱浮架系统进行了分析对比,得到方形网箱与圆形网箱的水动力特性的差异以及各自的优缺点,对实际中网箱的开发设计有一定的借鉴意义;通过计算,证明新型网箱浮架系统在工作海况能正常工作,在极端海况下也能满足安全性的要求;最后对4种常见系泊方式进行了时域耦合分析,得到了四种系泊方式的系泊特性,对实际工程中系泊方式的选择有一定的参考意义。

Research on Hydrodynamic Analysis and Mooring Method of a New Net Cage Floating Collar System

A new type of net cage floating collar system was designed,the software SESAM was employed to carry out to analyze the frequency domain hydrodynamics and the time domain coupling analysis considering the interaction of irregular waves,wind,flow loads and mooring force.Compared with the traditional double floating tube net cage floating collar system,the differences in hydrodynamic characteristics between square net cages and circular net cages and their respective advantages and disadvantages are obtained,It has certain reference significance for the development and design of the actual net cage;It is proved by calculation that the new net cage floating collar system can work normally in working sea conditions,and can meet the safety requirements under extreme sea conditions.Finally,the time domain coupling analysis of four common mooring methods is carried out,the mooring characteristics of four mooring methods are obtained,which has certain reference significance for the selection of mooring methods in practical engineering.
