🔍 Key Concepts

• Tankship documentation requirements in 46 CFR for hazardous liquid cargoes • Difference between a Certificate of Inspection (COI) and a Certificate of Adequacy or fitness for specific cargoes • What plans and regulations must be physically on board and available to the crew

💭 Think About

• Look at which documents are always required for any inspected tank vessel, and which are only required in special cases • Ask yourself: which item looks more like an internal ship plan or manual rather than a formal certificate issued by the Coast Guard or another authority? • Consider whether loading rates for piping systems are normally part of a required certificate or part of technical design/operations documents

✅ Before You Answer

• Verify in 46 CFR which certificates are explicitly required for tankships carrying hazardous liquids in bulk • Check which CFR parts are required to be carried on board tank vessels engaged in hazardous liquid cargo operations • Confirm whether a cargo piping plan with loading rates is specifically called out as a required carried document, or just something used in design/engineering
