MARINE TURBINE GEARING
The first AP propulsion units employing epicyclic gears as primary reduction and parallel shaft gears as secondary reduction went into service in 1965. Later triple reduction gearing for propeller speeds down to 80 rpm were introducted and the first unit of this kind was commissioned in 1967. Service experience from more than 100 units now installed in medium and large size tankers as well as high power container ships has been accumulated during a period which has seen rapid growth of ship sizes and propulsive power. This development has forced the engine and ship builder into closer cooperation during design, installation and commissioning stages. Much valuable experience has been gained which is also reflected in present and future design of gearing components and foundations and installation procedures. Some aspects of design and layout of gear will be given for future ships like 500,000 ton tankers and large high speed container ships.
