USCG Exam PracticeBearings, lubrication, and care of machine parts
Under federal regulations, steam turbine driven propulsion and auxiliary generating machinery that depends on forced lubrication must be arranged to do what upon failure of the lubricating system?
- A. Activate an audible alarm and reduce speed to one-third ahead
- B. Switch automatically to the gravity tank supply and continue operating
- ✓ Shut down automaticallyCorrect
- D. Transfer lubrication supply to the independent auxiliary pump and continue operating
Why C is correct
46 CFR §56.50-80(g) requires that steam turbine driven propulsion and auxiliary generating machinery depending on forced lubrication must be arranged to shut down automatically upon failure of the lubricating system. The emergency oil supply requirement in §56.50-80(i) is a separate provision ensuring lubrication until the equipment comes to rest during that automatic shutdown.
