Abstract

Deep-sea net cages play a vital role in expanding offshore farming in modern marine fisheries. In this paper, a model-scale 1:40 tank experiment was conducted for a vessel-shaped truss-structured single-point mooring deep-sea aquaculture net cage. The study focused on the hydrodynamic characteristics, including the effect of current, wave, and net on the mooring force, heave, and pitch motion behaviors. Experimental results indicate that the mooring force increases with the current velocity, draught of the cage, and wave height, but decreases with the wave period increase. Both heave and pitch movements amplitudes increase with wave height. While heave motion amplitude initially declines and then ascends with wave periods, pitch motion shows the opposite pattern. Besides the net has an obvious damping effect on the pitch motion. These results can provide data support for the design and offshore installation of vessel-shaped truss-structured net cages in the future.

半潜式船形鱼笼的流体力学性能实验研究

深海网箱在现代海洋渔业扩大离岸养殖方面发挥着重要作用。本文对船形桁架结构单点系泊深海养殖网箱进行了 1:40 模型比例水槽实验。研究的重点是水动力特性，包括水流、波浪和网对系泊力、起伏和俯仰运动行为的影响。实验结果表明，系泊力随流速、网箱吃水和波高的增加而增加，但随波浪周期的增加而减小。起伏和俯仰运动的振幅都随着波高的增加而增大。起伏运动振幅随波浪周期的变化先减小后增大，而俯仰运动振幅则与之相反。此外，网对俯仰运动有明显的阻尼作用。这些结果可为今后船形桁架结构网箱的设计和海上安装提供数据支持。

期刊介绍： Aquacultural Engineering is concerned with the design and development of effective aquacultural systems for marine and freshwater facilities. The journal aims to apply the knowledge gained from basic research which potentially can be translated into commercial operations. Problems of scale-up and application of research data involve many parameters, both physical and biological, making it difficult to anticipate the interaction between the unit processes and the cultured animals. Aquacultural Engineering aims to develop this bioengineering interface for aquaculture and welcomes contributions in the following areas: – Engineering and design of aquaculture facilities – Engineering-based research studies – Construction experience and techniques – In-service experience, commissioning, operation – Materials selection and their uses – Quantification of biological data and constraints
