Under 46 CFR §58.25-25, which condition must trigger both an audible and a visible alarm in the pilothouse?
- A. Overload of a steering-gear motor.
- B. Failure of any phase of a three-phase power supply to the steering gear.
- ✓ Low oil level in any hydraulic oil reservoir of a power-operated steering-gear system.Correct
- D. A 'motor running' indicator light failing to illuminate when the motor is energized.
Why C is correct
46 CFR §58.25-25(d)(3) requires an audible and visible alarm in the pilothouse upon occurrence of a low oil level in any oil reservoir of a hydraulic, power-operated steering-gear system. Motor overload (option A) and three-phase power failure (option B) trigger alarms in the machinery space under §58.25-25(e), not the pilothouse. The 'motor running' light (option D) is an indicator, not an alarm condition.
