영문 초록

In this study, a floating abalone farm system is analyzed using numerical modeling techniques. The floating structure is 24.5 m long and 12.5 m wide with 32 individual containment units deployed in a 4×8 configuration. The primary structural members are pipe made of high-density polyethylene with pinned connections forming walkways. The walkways are kept above the surface with Styrofoam billets. Nets are hung in each of the 32 squares that contain shelters for housing the abalone. A combination fluid-structure hydrodynamic and structural model of the farm was built to analyzed system response to environmental forcing. The model was loaded using combinations of forcing load cases induced by irregular waves and current velocities. Six load cases were simulated in two orthogonal directions. The conditions consisted of (1) a steady current of 1.0 m/s with an exponential decay to the bottom, (2) a JONSWAP irregular wave spectrum (Hmo=5.7 m, Tp=10.93 s), and (3) the irregular wave superimposed with the 1.0 m/s current decreasing with depth according to a power-law variation. With these conditions and orientations, hydrodynamic loads and critical stresses were calculated.
