On a vessel with hydraulic power-operated steering gear, which of the following alarm conditions must trigger both an audible and visible alarm in the pilothouse?
- A. Overload of any steering-gear motor.
- B. Failure of any phase of the three-phase power supply to the steering gear.
- ✓ Low oil level in any oil reservoir of the hydraulic steering-gear system.Correct
- D. Failure of the 'motor running' indicator light in the machinery space.
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 and phase failure alarms are required in the machinery space per §58.25-25(e), not the pilothouse.
