Testing the impact of simplifications adopted in models describing wave loads on ship

The waving-ship system in naval architecture is generally assumed to be a linear one. This allows for the computation of a transfer function of ship response to waves including wave loads on ship. The transfer function and the wave spectral density function enable the development of the stochastic process of wave loads on ship, corresponding to the irregular wave generating that loads. If the mathematical models of wave load transfer functions were to be used in the designing process, they would require simple mathematical forms. The paper presents the attempt of developing a simplified models of wave loads on ships.
