  • The old steam engines required astern turbines to move the ship backwards or stop her moving forward.
  • This system also made it possible to eliminate astern turbines.
  • The central engine room had two each low-pressure ahead and astern turbines as well as two cruising turbines driving the two center shafts.
  • The central engine room had two each low-pressure ahead and astern turbines as well as two cruising turbines driving the two centre shafts.
  • The central engine room had two low-pressure ahead and astern turbines as well as two cruising turbines driving each of the two center shafts.
  • Since ships are rarely operated in reverse, efficiency is not a priority in astern turbines, so only a few stages are used to save cost.
  • Astern turbines operated on the two wing shafts, with the central shaft idling when the ship was backing.
  • Each set consisted of high-pressure ahead and astern turbines driving an outboard shaft and a low-pressure turbine driving an inner shaft.
  • The high-pressure ahead and astern turbines drove the wing shafts while the low-pressure ahead and astern turbines drove the inner shafts.
  • The wing shaft was coupled to the high-pressure ahead and astern turbines and the low-pressure turbines to the inner shafts.
  • The wing shafts were coupled to the high-pressure ahead and astern turbines and the low-pressure turbines to the inner shafts.
  • The two inboard shafts were driven by the high pressure ahead and astern turbines, with the ahead turbines having an extra stage for cruising.
  • The two low pressure turbines incorporated "astern turbines" for reversing.
  • The wing propeller shafts were powered by high pressure ahead and astern turbines, while the inboard shafts were powered by low pressure turbines.
  • The high-pressure ahead and astern turbines were coupled to the outboard shafts and the low-pressure turbines to the inner shafts.
  • Parsons alleviated this problem by his suggestion of fitting more powerful astern turbines on all four shafts which could increase maneuverability by reversing the turbines as needed.
  • Each set consisted of high-pressure ahead and astern turbines driving an outboard shaft and low-pressure ahead and astern turbines, housed in the same casing, driving an inner shaft.
  • Each set comprised high-pressure ahead and astern turbines driving an outboard shaft and low-pressure ahead and astern turbines, housed in the same casing, driving an inner shaft.
  • The two inboard shafts were driven by the high pressure ahead and astern turbines with the ahead turbines having an extra stage for cruising, this was separated from the main turbine by a bypass valve.
  • The two inboard shafts were driven by the high pressure ahead and astern turbines with the ahead turbines having an extra stage for cruising; this was separated from the main turbine by a bypass valve.
