Q

On a vessel equipped with marine propulsion gas turbines, the operator’s initial response to a high vibration alarm should be which of the following?

🔍 Key Concepts

• Initial response actions to machinery alarms, especially on high vibration • Relationship between shaft/rotor speed and vibration severity in rotating machinery • Risks of delaying action vs. taking immediate, conservative action on a gas turbine

💭 Think About

• If a rotating machine starts to vibrate excessively, what simple operating change can you make right away from the control console, without tools or parts? • Which choice would be unsafe because it assumes the problem will fix itself without any operator action? • Which options involve maintenance or troubleshooting steps that are NOT appropriate as the very first response to an alarm?

✅ Before You Answer

• Identify which option represents an immediate operational adjustment rather than maintenance or instrumentation work. • Eliminate any choice that relies on the vibration going away on its own. • Eliminate any option that requires physical replacement of components or complex verification before taking protective action.
