Question 1 of 27070

Q

During the inspection for certification of small passenger vessel of less than 100 gross tons, a hydrostatic test of 1-1/4 times the maximum allowable working pressure shall be made to __________.

🔍 Key Concepts

• 46 CFR Subchapter T – Small Passenger Vessels under 100 Gross Tons • Hydrostatic test requirements and typical test pressures for pressure vessels • Difference between main boilers and auxiliary pressure vessels (heat exchangers, accumulators, etc.)

💭 Think About

• Which of these systems, if they failed under pressure, would most directly endanger passenger safety and therefore justify a specific hydrostatic test requirement? • Think about which items are normally designed and regulated as pressure vessels rather than just system components. • Which of these choices is most likely to have its own separate certification and inspection regime outside of the small passenger vessel rules?

✅ Before You Answer

• Verify in 46 CFR Subchapter T which equipment explicitly requires hydrostatic testing at 1.25 × MAWP (maximum allowable working pressure). • Check whether small passenger vessel inspection rules treat oil‑fired boilers differently from smaller auxiliary pressure vessels like heat exchangers. • Confirm which of the listed items are typically classified as unfired pressure vessels rather than fired boilers.
