Which item is explicitly listed as a monitored parameter in engine room automation systems?

• A. RPM, temperatures, pressures, fuel flow, lube oil pressure, vibration, alarms, and operating load
• B. Hull color
• C. Weather forecast
• D. Radio signal strength

Answer: (A)

Engine room automation is designed to continuously monitor the signals that reflect the safe and efficient operation of propulsion and auxiliary machinery. The monitored parameters—RPM, temperatures, pressures, fuel flow, lube oil pressure, vibration, alarms, and operating load—are exactly the types of data the system uses to detect abnormal conditions and trigger control actions or alarms. RPM controls speed and helps detect overspeed; temperatures alert to overheating in components like the engine, jacket water, or exhaust; pressures indicate leaks, blockages, or failures in fuel, lubrication, or cooling circuits; fuel flow verifies that the engine is receiving the correct amount of fuel for its current load; lube oil pressure ensures bearings and moving parts remain properly lubricated; vibration can reveal misalignment, imbalance, or bearing wear; alarms provide explicit fault indications; operating load shows the current power demand and helps manage safety margins and governor actions. The other choices don’t pertain to engine room operation or safety, so they aren’t listed as monitored parameters.
