🔍 Key Concepts

• 46 CFR requirements for inspection and testing of marine boilers • Differences between periodic inspection for certification and special tests like hydrostatic tests • What items are considered boiler mountings (safety valves, water gauges, etc.) and how often they must be opened up

💭 Think About

• Ask yourself: Is removal of boiler mountings something done only during a special test, or as part of the regular inspection cycle for the vessel? • Think about how critical boiler mountings are to safety. Would the Coast Guard likely wait many years between required internal examinations? • Consider which 46 CFR sections deal with inspection intervals for pressure vessels and boilers—do they tie this work to a specific test, or to each certification period?

✅ Before You Answer

• Verify in 46 CFR how often an inspection for certification is required for the type of vessel you are thinking about • Check whether the regulations link the removal of boiler mountings and examination of studs to a calendar interval (years) versus an event (like hydrostatic test or inspection for certification) • Confirm in 46 CFR that hydrostatic tests have their own specific triggers and intervals, which may or may not be the same as the requirement for removing boiler mountings
