While a vessel is underway, one of the FIRST indications of the failure of the gland leak off exhaust fan motor is __________.

🔍 Key Concepts

• purpose of the gland leak off exhaust fan in a steam turbine system • normal direction of steam and air flow around turbine glands when equipment is operating correctly • what happens to pressure and temperature in the exhaust and gland areas if the exhaust fan suddenly stops

💭 Think About

• Think about what the gland leak off exhaust fan is trying to remove during normal operation. If it stops, what changes first: steam flow pattern, pressure, temperature, or mechanical damage? • Consider which symptom would appear earliest: a gradual change in turbine conditions (like temperature or vacuum) or a local change right at the glands and leak‑off system. • Ask yourself: which option reflects an effect that would occur directly and quickly at the gland leak off system, rather than a later, indirect effect on the turbine as a whole?

✅ Before You Answer

• Be clear on the function of the gland leak off exhaust fan: does it primarily control vacuum, temperature, or removal of vapors/air from glands? • Decide which choices describe primary/initial effects (local to the glands) versus secondary effects (overall turbine performance). • Verify which symptom would be noticed by the engineer first on rounds near the glands and leak‑off header, before any significant change shows up in turbine vacuum or exhaust temperature.
