Parametric modeling and application of gravity deepwater cage system

The numerical model of gravity deepwater cage, which is the foundation for the numerical simulation analysis of mechanical characteristics of cage, undertakes the majority of the work in the cage simulation process. In order to solve the problems of tedious modeling and low efficiency in this process, we proposed a parameterized rapid modeling method for gravity deepwater cage. Firstly, each component of the cage was parameterized according to its structural characteristics. Then, the modeling program was compiled and the corresponding operation interface was developed. Finally, the rapid creation of gravity deepwater cage model was achieved in OrcaFlex. Engineering test shows that the program can improve the efficiency of cage modeling greatly and facilitate the engineering calculation of gravity deepwater cages. The study provides references for the model rapid creation and numerical analysis of gravity deepwater cages of various specifications.
