In high-speed ships, the main engine is required to have a large output, resulting in the installation of propellers of large diameter. On the other hand, it is difficult to obtain enough immersion for the propeller because of the limitation caused from the hull form in high speed ships, such as a container ship. This difficulty causes such a ship to be subject to so-called racing of the propulsion system when the ship sails on a rough sea. The racing is undesirable for the operation and reliability of the main engine. This report describes the investigation made on the dynamic performance of the propulsion system to prevent the racing phenomena. The exact information about an actual ship, were measured on a container ship "America Maru", during her voyage between Japan and U.S.A. Then, the dynamic performance of the system was studied with the simulation technique. The result shows that a properly readjusted governor of conventional type may reduce the speed variation of the propeller. But this should be investigated more in detail by an actual ship test before actual application.
