According to 33 CFR's, an oceangoing ship of over 400 gross tons must be fitted with a standard discharge shore connection. What size bolt circle diameter is required for this shore connection to transfer oily ballast to a shore side reception facility?
AI Explanation
The correct answer is B) 183 mm.
According to 33 CFR 155.420, an oceangoing ship of over 400 gross tons must be fitted with a standard discharge shore connection to transfer oily ballast to a shore-side reception facility. The regulation specifies that the shore connection must have a bolt circle diameter of 183 mm (7.25 inches).
The other options are incorrect because they do not match the bolt circle diameter requirement set forth in the regulations. Option A (125 mm) and Option C (215 mm) are the wrong sizes, while Option D (250 mm) is too large for the standard discharge shore connection.
