🔍 Key Concepts

• Condensation forms when warm, moist air contacts cooler metal surfaces, especially during shutdown and cool-down periods • The role of lubricating oil circulation in warming or cooling machinery and carrying away moisture • Distinguish between practices that protect the gear from condensate and corrosion versus those that mainly protect from overheating or low pressure

💭 Think About

• Think about when condensate is most likely to form in a gear casing: during steady full‑load operation, or during cool‑down after shutdown? • Which choice directly affects the temperature relationship between the gear casing, the lubricating oil, and the surrounding engine room air? • Which options are more about general operating limits (temperature, pressure) rather than specifically preventing water condensation inside the gear casing?

✅ Before You Answer

• Identify which option specifically mentions actions taken after the main unit is secured and how that would influence condensation risk • Check which choices are primarily about normal operating limits (like max oil temperature or minimum pressure), which do not directly target condensate formation • Verify which practice would help the metal casing and oil reach the same temperature as the engine room air, reducing the conditions that cause condensation

Question 1 of 20

Which of the following operational practices is helpful in avoiding the accumulation of condensate in the main reduction gear casing?

After the main unit is secured, lubricating oil should be circulated until the temperature of the oil and reduction gear casing approximates the engine room temperature.

The temperature of the lubricating oil should not exceed the gear manufacturer's recommendation when the unit is operating at full load.

Avoid applying gland sealing steam to the low-pressure turbine until you are ready to start up the first- stage air ejector.

Always ensure that the lubricating oil pressure is 14-17 psi when operating in unusually cold waters.
