USCG Exam PracticeAuxiliary machinery and shipboard systems
A vessel's main steering gear uses a hydraulic power actuating system. After a single failure in the piping system, 46 CFR §58.25-10(f)(3) requires that the defect be isolated and steering capability maintained or speedily regained within what time limit, in order for the vessel to omit a separate auxiliary steering gear?
- A. 28 seconds
- B. 5 minutes
- ✓ 10 minutesCorrect
- D. 60 seconds
Why C is correct
46 CFR §58.25-10(f)(3) requires that after a single failure in the hydraulic piping system or in one of the power units, the defect can be isolated so that steering capability can be maintained or speedily regained in less than ten minutes. The 28-second and 60-second figures are rudder movement performance standards, not isolation time limits.
