🔍 Key Concepts

• 46 CFR Subchapter F (Marine Engineering regulations) covering boilers and pressure vessels • Roles and responsibilities of a marine inspector vs OCMI (Officer in Charge, Marine Inspection) and COTP (Captain of the Port) • Who is authorized to witness and accept statutory tests like boiler safety valve setting

💭 Think About

• Which of these positions is typically present specifically to witness and verify technical inspections and tests on machinery and equipment? • Think about who has the legal authority to sign off that the boiler’s safety devices meet federal requirements, not just shipboard or local operational requirements. • Among the options, who is most commonly physically present during Coast Guard inspections in a shipyard or at the plant when equipment is tested?

✅ Before You Answer

• Verify in 46 CFR Part 61 – Periodic Tests and Inspections (and related boiler test provisions) who must be present for safety valve setting. • Distinguish between COTP (port safety/security role) and OCMI (overall inspection authority) versus the individual who actually conducts inspections. • Remember that the chief engineer is responsible for shipboard operation and maintenance, but consider whether that satisfies a regulatory witnessing requirement.
