Question 1 of 27070

Q

According to Coast Guard Regulations (46 CFR), what action should be taken if the metal thickness of a marine boiler is found to be thinner than original specifications?

🔍 Key Concepts

• 46 CFR requirements for pressure vessels and boilers regarding wastage or reduced thickness • Relationship between metal thickness, safety factor, and allowable working pressure in boilers • Difference between repairing, replacing, and derating (lowering pressure) a boiler or drum

💭 Think About

• If the plate or drum is still sound but thinner than original, which regulatory action most directly addresses safety while still possibly allowing use? • Which option would likely be reserved for severe, unsafe conditions where the boiler can no longer be operated at all? • Which option reflects a calculated, engineering-based response rather than a physical repair or immediate condemnation?

✅ Before You Answer

• Check which option involves engineering calculations based on actual measured thickness and safety factors from 46 CFR. • Decide whether Coast Guard regulations typically require automatic condemnation for any thinning, or allow continued use under adjusted conditions. • Consider whether simply welding over thin areas is generally acceptable on pressure parts of a boiler under USCG rules, or if that raises additional safety concerns.
