🔍 Key Concepts

• 46 CFR requirements for repairs to pressure vessels, such as ship’s service air receivers • The role and authority of the Officer in Charge, Marine Inspection (OCMI) for repairs affecting safety • Difference between onboard operational checks by crew and regulatory approval/inspection by the Coast Guard

💭 Think About

• Ask yourself: which option talks about the Coast Guard’s regulatory control over a pressure vessel before work is done, versus what the ship’s crew does after the work? • Consider: for a welded repair on a pressure vessel (not an emergency at sea), does the CFR emphasize specific welding technique, multiple tests, or official approval/oversight? • Think about which person or office, if any, must be involved before the repair proceeds under 46 CFR.

✅ Before You Answer

• Verify in 46 CFR Part 61 (periodic tests and inspections) and related sections on repairs to boilers and pressure vessels what it says about authorization for welded repairs. • Check which choice, if any, explicitly involves the OCMI/Marine Inspection rather than just the ship’s crew. • Confirm whether the regulation talks about a required approval/authorization step before repair, instead of only post-repair testing.
