During engine-room rounds, a watchstander notices that lube-oil temperature has been slowly rising over the past two hours but has not yet triggered an alarm. What is the correct response?
- A. Continue rounds and re-check the reading at the next scheduled interval
- B. Silence the alarm panel to prevent a nuisance alarm
- ✓ Investigate the trend and report it up the chain of responsibilityCorrect
- D. Record the reading in the log and take no further action unless the alarm activates
Why C is correct
NAVEDTRA 14104 §1-2 states that trends matter more than single readings and that a temperature slowly drifting off normal is an early warning of fouling, wear, or developing failure. Any reading outside its normal band is investigated and reported, not simply written down.
