Question 1 of 27070

During each two and one-half year inspection, which test or examination of a cargo vessel water tube boiler is required by Coast Guard Regulations (46 CFR)?

🔍 Key Concepts

• 46 CFR requirements for inspection of steam and water-tube boilers on cargo vessels • Differences between operational tests (e.g., safety valve accumulation tests) and physical examinations (e.g., fireside or hydro tests) • Typical intervals: what is done at initial construction vs. periodically in service

💭 Think About

• Ask yourself which of these options would reasonably be repeated every 2.5 years without taking the boiler completely out of service for a long period • Consider which exam focuses on the internal gas‑side condition of the boiler rather than the pressure boundary strength • Think about which tests are usually reserved for initial certification or after major repairs because of the stresses they place on the boiler

✅ Before You Answer

• Verify in 46 CFR Part 61 (Periodical tests and inspections) which item is specifically tied to the two and one‑half year inspection interval • Check which of the listed tests is described as a visual inspection rather than a pressure or safety‑valve performance test • Confirm which procedure is normally required only at 5‑year or longer intervals, or after major repairs, and therefore can be ruled out for a 2.5‑year routine inspection
