Abstract : A comparison is made between four methods of determining the heave and pitch responses of a ship in waves. Full scale data were obtained from measurements in normal merchant service conditions on board the Belgian cargo liner M. V. JORDAENS. Model tests were carried out on a 1/100 scale model in regular and irregular waves in the same conditions as those encountered at sea. Theoretical computations were made using Linear Strip Theory with Grim's coefficients. Wave measurements at sea were obtained with a Tucker shipborne wave recorder. An attempt was made to reproduce the same irregular pattern in the model tank. A comparison of bending moments measured on the ship and computed by strip theory is also presented. (Author)
