Q

What is NOT a requirement of cargo piping installed in tank vessels carrying grade D or E cargo ONLY?

🔍 Key Concepts

• Grade D and E cargo definitions in 46 CFR (combustible vs flammable characteristics) • General cargo piping construction requirements for tank vessels carrying lower-hazard grades only • When the rules require piping to be fixed versus allowing more flexibility (e.g., portable or non-fixed arrangements)

💭 Think About

• Compare which of the four statements looks like a general good engineering practice that would likely apply to almost all cargo piping, regardless of cargo grade. • Think about whether lower-hazard grades (D and E) would still require the same strictness on joint types and bulkhead penetrations as higher-hazard grades. • Ask yourself: which option describes something that sounds more like an operational preference than a hard construction requirement in the regulations?

✅ Before You Answer

• Look in 46 CFR, tank vessel piping requirements to see which items are explicitly listed as mandatory for Grade D/E cargo only vessels. • Verify whether the regulations actually say that the cargo piping system "shall be fixed" for Grade D/E only vessels, or if that wording applies only to higher grades. • Confirm whether bulkhead connections and flange/joint details are specifically regulated for these lower grades in the same way they are for higher grades.
