SHIP MODEL TESTS IN IRREGULAR SEAS AND CORRELATION WITH FULL SCALE TRIALS

摘要

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 Professor Ae ssen who conducted measurements in normal merchant service conditions on board the Belgian cargo liner M,V, JORDANS. Model tests were carried out on a l/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 ship borne 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.
