Study On Stability Of Aquaculture Unit In Deep Sea

With the depletion of offshore fishing resources becoming more and more serious,deep-sea aquaculture has gradually become an important source of fishery resources,and many countries are also vigorously developing deep-sea aquaculture.Deep-sea culture units are the most important vehicle for fishery culture and researchers learning a little about deep-sea culture units as a new thing,so the research for culture units is very necessary and urgent.Nowadays,the classification societies of many countries are basically in the exploratory stage for the stability specification of aquaculture unit,and have not conducted in-depth research and formulation of the specification.Therefore,first of all,according to CCS,DNV and ABS,this paper compares the similarities and differences of the three specifications,and puts forward suggestions according to the characteristics of the new type unit to promote the further improvement of the specifications.Then,the process of stability checking for the deep-sea unit will be further combed and explored.And the intact stability and damage stability of the deep-sea unit are discussed according to the analysis steps.With the secondary development function of NAPA software,the stability of the unit under the transit,survival and operational conditions is analyzed to obtain the stability calculation results of the unit,including the floating state,the ultimate height of gravity center(ACG),the damage stability and other data.Finally,according to the structural characteristics of the target unit,the stability characteristics of the deep-sea aquaculture platform in waves are explored in this paper.Meanwhile,based on the calculation results of the unit stability in waves,suggestions for improving the structure of the target unit are put forward to improve the stability of the unit against waves.
