Which of the pressure vessels listed is required under Coast Guard Regulations (46 CFR) to be hydrostatically tested once every three year period?

🔍 Key Concepts

• 46 CFR requirements for pressure vessel inspection and testing intervals • Differences between internal inspection and hydrostatic test requirements • Which types of pressure vessels may be exempt from manhole/entry inspection but still require periodic hydro tests

💭 Think About

• Look up each listed item in 46 CFR and note whether it is treated as a pressure vessel or another type of equipment with different inspection rules • Compare the required hydrostatic test intervals for vessels that can be entered (with manholes) versus those that cannot be entered • Ask yourself which of these items is most safety‑critical if it failed suddenly under pressure, and how that might affect the required testing frequency

✅ Before You Answer

• Verify in 46 CFR Subchapter F (Marine Engineering) and associated sections that specify hydrostatic test intervals for pressure vessels • Confirm whether each option is explicitly called out in the regs (not just treated as generic piping or tanks) • Check if the regulation mentions a three‑year interval specifically for one of these types of vessels, and not for the others
