What color are obstruction lights on mobile offshore drilling units that are located on the waters of the U.S. Outer Continental Shelf seaward of the line of demarcation?
AI Explanation
The correct answer is B) White.
Mobile offshore drilling units located on the waters of the U.S. Outer Continental Shelf seaward of the line of demarcation are required to display white obstruction lights, according to the regulations set by the U.S. Coast Guard. This is specified in the Code of Federal Regulations (CFR) Title 33, Section 67.10-5, which states that "All obstructions shall be marked with white lights." The other options (blue, yellow, and red) are incorrect as they do not match the regulatory requirement for white obstruction lights on these offshore structures.
