In which turbine are the astern turbine elements located?

The astern turbine elements are located in the low pressure turbine. This design allows for efficient operation when the engine is working in reverse thrust mode, which is essential for slowing down or maneuvering a vessel. In marine propulsion systems, the low pressure turbine typically handles steam that has already expanded through the high pressure and medium pressure turbines, making it ideal for accommodating the additional requirements of reverse thrust.

Low pressure turbines are designed for operation at lower pressures and temperatures, allowing them to efficiently utilize steam that is not suitable for high pressure turbines. When the ship needs to move astern, these low pressure turbine elements engage to provide the necessary thrust in the opposite direction. This mechanical arrangement ensures that the ship can effectively respond to navigational commands, enhancing safety and maneuverability during operations.
