漂浮式风机融合养殖网箱结构完整稳性分析

Intact Stability Analysis of Floating Offshore Wind Turbine Integrated with Fish Farming Cage

为提高漂浮式风电经济效益,并顺应远海网箱养殖向深远海发展需求,采用漂浮式风机融合养殖网箱以满足两者发展需求。对结构的完整稳性进行分析,采用网衣群目化算法运用莫里森杆件对网衣结构进行数值仿真,并运用Sesam软件建立数值仿真模型,依据美国船级社(ABS)规范对运行工况不同风推力入射角度下的结构完整稳性进行评价,得出0°入射方向所对应倾斜轴为结构完整稳性最不利倾斜轴。分别研究网衣及侧立柱直径对平台稳定性的影响。结果表明,网衣会优化平台稳定性,侧立柱直径则会对静稳心高度产生影响,在一定范围内增大侧立柱直径可优化结构稳定性。

In order to improve the economic efficiency of the floating offshore wind turbine and promote the development of distant sea fish cage aquaculture to deep sea,the floating offshore wind turbine integrated with a fish farming cage is used to meet the development needs of both.The intact stability of the structure is analyzed.Morrison's bar is used to numerically simulate the mesh structure using the mesh group visualization algorithm,and the numerical simulation model is established using Sesam software.According to the American Bureau of Shipping(ABS)regulations,the structural intact stability under different wind incident angles of operating conditions are evaluated,and the tilt axis corresponding to the 0°incident direction is determined to be the most unfavorable tilt axis for the structural intact stability.The influence of the mesh and side column diameter on the platform stability is studied separately.The results show that the mesh will optimize the stability of the platform,while the diameter of the side columns will affect the height of static stability,and increasing the diameter of the side columns within certain range can optimize the stability of the structure.
