Question 722Steam Plants - Assistant Engineer
70% to passIn a cross compound main propulsion unit, the astern turbine is usually installed at the _______________.
Alow-pressure end of the low-pressure turbine
Bhigh-pressure end of the high-pressure turbine
Chigh-pressure end of the low-pressure turbine
Dlow-pressure end of the high-pressure turbine
AI Explanation
The correct answer is A) low-pressure end of the low-pressure turbine. In a cross compound main propulsion unit, the astern turbine is typically installed at the low-pressure end of the low-pressure turbine. This arrangement allows the astern turbine to be connected to the same shaft as the main propulsion turbines, enabling effective reversal of thrust for maneuvering the vessel. The other options are incorrect because: B) and D) do not align with the typical configuration of a cross compound main propulsion unit, and C) would place the astern turbine in a less efficient location within the system.
