The design of a marine system, divided into three steps, is examined. Steady, alternating forces and moments, generated by the propeller are discussed and their calculation method is shown. Optimization criteria with respect to shaft strength as well as longitudinal and vertical bearings position are given. Longitudinal, lateral, torsional vibration problems and their influence on shafting design are discussed. A new method for the propeller shaft diameter calculation, useful when the bearing forces versus the angular position of the shaft are available, is presented.
