USCG Exam PracticeWatch duties, terminology, and instrumentation
An oiler on watch notices that a bearing temperature has been slowly rising over the past two hours but has not yet reached the alarm setpoint. What is the correct action?
- A. Record the reading in the log and continue rounds; take no further action until the alarm activates
- B. Immediately secure the associated machinery without notifying the watch engineer
- ✓ Investigate the trend and report it to the watch engineer without waiting for the alarmCorrect
- D. Increase lubricating oil flow manually and log the adjustment as a routine entry
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 a good watchstander catches before an alarm does. Any reading outside its normal band is investigated and reported, not simply written down.
