70% to passAccording 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?
A125 mm
B183 mm
C215 mm
D250 mm
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.
