In this paper, numerical modeling and model testing of a complex-shaped remotely-operated vehicle (ROV) were shown. The paper emphasized the systematic modeling of hydrodynamic damping using the computational fluid dynamic software ANSYS-CFX™ on the complex-shaped ROV, a practice that is not commonly applied. For initial design and prototype testing during the developmental stage, small-scale testing using a free-decaying experiment was used to verify the theoretical models obtained from ANSYS-CFX™, Simulation results are shown to coincide with the experimental tests. The proposed method could determine the hydrodynamic damping coefficients of the ROV.
