🔍 Key Concepts

• 33 CFR oily-water discharge shore connection requirements for ships of 400 GT and above • Exact standard flange dimensions (diameter, bolt holes, thickness, etc.) specified in the regulation • Difference between pressure rating, pipe internal diameter limits, and flange geometry/bolt pattern

💭 Think About

• Which of these answer choices sounds like a very specific geometric description of a flange face rather than a general performance or size limit? • Look at how international/US standards are usually written: do they more often prescribe exact dimensions for a standardized connection, or broad limits like ‘up to a maximum diameter’ or ‘suitable for a pressure’ for this kind of fitting? • Ask yourself: for a visiting ship to hook up easily to any port reception facility, which flange characteristic must be identical worldwide so that hoses line up every time?

✅ Before You Answer

• Verify in 33 CFR 155 (oil pollution prevention) the exact wording for the standard discharge connection dimensions. • Check which option describes a fixed, numeric flange feature (like thickness, bolt pattern, or diameter) that would need to match between ship and shore. • Confirm whether the regulation actually states anything about service pressure or maximum pipe internal diameter, or if it focuses instead on the flange’s physical layout for compatibility.
