The application of the aero‐derivative gas turbine to warship propulsion is described in detail.

    Comparisons of the different roles of the warship and aircraft are made to better understand the marine propulsion system solutions and methods of operation and control.

    The demanding marine environment is discussed including the effects and mitigation of salt spray, green water exposure, inlet and exhaust location relative the engine installation and the need for infrared suppression.

    Accommodation of the wide range of operational requirements has lead to complex machinery arrangements with boost and cruise engines operating separately or in combination together with a Controllable Reversible Propeller (CRP).

    Ancillary systems are described including blow‐down starting and engine washing systems, fuel supply and purification systems.

    The importance of modeling of the ship and its propulsion machinery as an essential tool for understanding and optimizing the various control modes and machinery combinations is emphasized. A typical control strategy is presented wherein powerplant selection to match ship requirements is automated as well as the scheduling of throttle and propeller pitch to meet immediate ship speed demands during various maneuvers.
