舱养式深远海养殖平台的水动力及单点系泊特性

Hydrodynamics and Single-Point Mooring Characteristics of Deep-Sea Tank Breeding Aquaculture Platform

建造深远海养殖平台对我国海水养殖业具有重大意义,舱养式养殖平台作为创新型特殊船舶,应对其水动力及系泊问题进行针对性研究。在频域内研究6对大型养殖水舱对横摇水动力性能的影响,根据系泊要求建立单点系泊系统,进行时域耦合系泊分析。分析结果表明,养殖水舱对平台水动力特性有不可忽略的影响;平台在长时间经历极端工况后会产生较大的"鱼尾运动"。研究结论对此类新型海上结构物的系泊安全研究具有一定的参考价值。

Deep-sea aquaculture platform has great significance for the sea breeding industry in China.As an innovative special ship,the tank breeding aquaculture platform should carry out a targeted study on the hydrodynamics and mooring problem at sea.The effect of six pairs of large-scale fish culture tanks on hydrodynamic performance of rolling is studied in the frequency domain.According to the mooring requirements,a single-point mooring system is established and a time-domain coupled mooring analysis is performed.The results show that the fish culture tanks have a non-negligible impact on the hydrodynamic of the platform.Under long-time extreme conditions,the platform will occur big"fishtailing motion".The study has certain reference value for the research on the mooring safety of such new type offshore structures.
