To determine what navigation lights and day-shapes must be displayed on mobile offshore drilling units under tow, you should check the _______________.
AI Explanation
The correct answer is D) International Regulations for Preventing Collisions at Sea.
The International Regulations for Preventing Collisions at Sea (COLREGS) are the international standards that govern the navigation lights and day-shapes required for all vessels, including mobile offshore drilling units under tow. The COLREGS provide detailed specifications on the navigation lights, shapes, and signals that must be displayed by different types of vessels to indicate their status and intended movements. This makes the COLREGS the authoritative source for determining the required navigation lights and day-shapes for mobile offshore drilling units under tow.
The other options are incorrect because they do not contain the comprehensive international standards for navigation lights and shapes that are specified in the COLREGS.
