70% to pass

Where will you find the requirements for the lights that must be displayed on a mobile offshore drilling unit that is being towed?

A Coast Pilot
B COLREGS
C Notice to Mariners
D Light List
AI Explanation

The correct answer is B) COLREGS. The requirements for the lights that must be displayed on a mobile offshore drilling unit that is being towed are specified in the International Regulations for Preventing Collisions at Sea (COLREGS). The COLREGS contain the international rules for navigation and safe operation of vessels, including the lighting requirements for various types of vessels and structures. The other options are incorrect because the Coast Pilot and Light List do not contain the specific regulations for mobile offshore drilling units, and the Notice to Mariners is a publication that provides temporary or urgent updates to navigational information, rather than the comprehensive regulations.
