“…The obtained values of the dimensionless added mass coefficients and the damping coefficient for the solid plate are close to those presented in the literature, e.g. as reported by Medina-Manuel et al [7]. Based on the presented values, it can be concluded that the greater the excitation amplitude, the greater the value of both the added mass and the damping coefficient.…”

“…Medina-Manuel et al [7] conducted model studies of a heave plate cylinder with a large plate diameter to cylinder diameter ratio (Dhp/D ~ 2.9) in a wide range, changing both the motion amplitude and the excitation frequency. Using two methods, forced and free oscillations, they determined the values of the hydrodynamic coefficients of the tested plate.…”

One of the methods of modelling the movement of floating wind turbines is the use of the diffraction method. However, this method does not take into account the influence of viscosity; therefore, in many cases, it needs to be extended with a matrix of appropriate coefficients. The effect of viscosity causes both the added mass coefficient and the damping coefficient to increase. The determined coefficients were entered into the ANSYS AQWA program, and the calculation results of the transfer function determined with the use of linear and quadratic damping were presented. The results were compared with the results of the experiment, indicating greater convergence for the quadratic model.
