碩士 / 國立中山大學 / 海洋環境工程研究所 / 85 / A two-dimensional time-domain lumped parameter model for predicting the dynamic responses of cage aquacultural mooring system in an ocean environment is presented. Numerical integration techniques of fifth-order Runge-Kutta-Cash-Karp method is employed in the time stepping procedure. Numerical analysis consists of determining the tether tensions and the motions of mooring cage. Laboratory experiments with cage mooring system model have been made to determine the drag force necessary to describe the cage motions in the numerical model. Tensions and motions test in linear wave with steady flow have also been made.
Comparisons between the numerical model and physical model are good, thus, the extension of this numerical model for predicting the cage mooring system response can be made. The result has shown that the general mooring system would not restrict the cage heave motion; while the surge motion of cage and the tether tensions are greatly effected by the buoy buoyancy and the tether length.
