🔍 Key Concepts

• 46 CFR vapor control systems requirements for tank vessels and facilities • Standardized vapor connection flange design to ensure safe, gas-tight connection • Why projections or fittings on a flange face might affect tight sealing

💭 Think About

• Look at which option would be required on every vessel’s vapor connection flange—not just sometimes useful equipment. • Consider what must be standardized so any shore connection can safely mate to any vessel’s vapor flange. • Think about what fittings or attachments placed on the flange face might interfere with getting an even gasket seal against the mating flange.

✅ Before You Answer

• Verify in 46 CFR Part 39 (Vapor Control Systems) what is specified for the design of the vessel’s vapor connection flange. • Check which choices would be permanently required on all vessels, versus optional or situational equipment. • Be sure the requirement applies to the flange itself, not to nearby piping, monitoring, or hose‑support gear.
