🔍 Key Concepts

• 33 CFR Subchapter O requirements for oily-water discharge connections • Standard flange dimensions for ship-to-shore oily ballast transfer • Relationship between bolt circle diameter, outside diameter, and number/size of bolts

💭 Think About

• Look up the regulation table that lists the standard discharge shore connection flange dimensions and compare the listed bolt circle diameter with the answer choices. • Consider how the bolt circle diameter normally relates to the overall flange outside diameter for this standard connection—does the circle tend to be much smaller, slightly smaller, or almost the same? • Ask yourself which of the options is consistent with an internationally standardized flange intended to match reception facilities in most ports.

✅ Before You Answer

• Verify the exact table and line in 33 CFR Subchapter O that specifies the standard discharge shore connection dimensions. • Confirm that you are looking specifically at the row for oily ballast (not sewage or ballast water only) on an oceangoing ship over 400 GT. • Double‑check that the value you select is explicitly labeled as bolt circle diameter, not outside diameter or bolt hole diameter.
