Question 1 of 270705eccefa0bacbc34ba4d47065

A periodic hydrostatic test is being performed on an oil-fired auxiliary water-tube boiler with a maximum allowable working pressure of 150 psig. In accordance with 46 CFR 61, what is the required hydrostatic test pressure for this procedure?

Question 1 of 27070

🔍 Key Concepts

• 46 CFR 61 requirements for periodic hydrostatic tests on marine boilers • The definition of maximum allowable working pressure (MAWP) and how test pressure is related to it • Typical test pressure percentage used for boilers during periodic inspections

💭 Think About

• Look up the exact percentage of MAWP that 46 CFR 61 specifies for a periodic hydrostatic test of a water-tube boiler, not a new construction test • Once you find the required percentage, multiply it by the 150 psig MAWP and compare the result with the answer choices • Consider whether the regulation calls for a higher one-time test pressure (like for initial certification) or a lower recurring test pressure (like for periodic inspections)

✅ Before You Answer

• Verify the exact CFR citation for periodic hydrostatic testing of boilers (not pressure vessels in general) • Confirm the percentage of MAWP required for periodic tests as opposed to initial tests • Double-check your pressure calculation and rounding so it matches one of the listed choices
