Design Considerations and Selection of Controls for Vessels Equipped With Controllable-Pitch Propellers

The propulsion control system of a vessel equipped with a controllable pitch propeller is discussed along with factors influencing its design. These factors are the hull, propeller, and prime mover (diesel, gas-turbine, and steam) characteristics and the vessel's operating requirements. The system is also discussed in relationship to such special problems as vessels with a high displacement to horsepower ratio. The appendix includes a complete description of the propulsion control system in 352 ft passenger ferries.
