In the initial design stage of ships, various problems are examined prior to the detailed design. Among these, propulsive performance in the steady state is the most vital one, which is directly related to ship's dimensions, main engine output and ship's navigation speed and is the base of various other examination items. Meanwhile, the recent tendency toward tankers of enormous size and container ships or ocean-going car ferries of high power and speed produces critical problems from a hydrodynamic view point. These matters require systemization and high efficiency in the initial design procedure, i.e., the application of a computer to the design system is desired, which enables us to make more accurate examination much sooner, to determine the ship's principal dimensions, main engine output and stern form which have direct influences on propulsive performance or hull vibration. These considerations have resulted in a computer program--PPP (propeller design and performance calculation program)-which is concerned with propeller design as a main part and ship's propulsive performance calculation as a chain in the system. Its design concept, contents and effects are outlined in this paper.
