Liu, ZC. and Guedes Soares, C. (2024), Numerical study on the optimisation of the mooring system of gravity cage systems, International Innovation & Cooperation in Naval Architecture and Marine Engineering Conference (ICNAME 2024), 22-25 August, Harbin, China.
A numerical model is built to study the performance of the mooring system, which is connected to both the top and the bottom of a gravity cage. As a flexible structure, the volume of the gravity cage reduces when subjected to currents and waves. This work studies whether it is possible to protect the cage volume by connecting the mooring ropes to the cage bottom. The mooring ropes are connected to the floating collar and the bottom ring. Line elements are used in the finite element model of the slender structures. From the numerical calculation, the cage volumes are maintained at a high flow velocity by connecting the mooring ropes on the bottom ring, but the mooring force increases. The longer the mooring ropes, the smaller the mooring force, but it has almost no effect on the cage volume. In addition, Changing the connection position causes a significant increase in the tension of the connecting ropes between the floating collar and the bottom ring and considerably deforms the bottom ring, necessitating further structural analysis.
