70% to pass

Where will you find the requirements for the signals that must be sounded by a mobile offshore drilling unit that is being towed through an area of restricted visibility?

A SOLAS Convention
B COLREGS
C Coast Pilot
D MMS Rules
AI Explanation

The correct answer is B) COLREGS. The COLREGS (International Regulations for Preventing Collisions at Sea) are the international rules that govern the signals and lights that vessels, including mobile offshore drilling units, must display in various situations, including when operating in restricted visibility. The COLREGS specify the sound signals that a mobile offshore drilling unit being towed must make to indicate its status and position to other vessels in the area. The other options are incorrect because: A) The SOLAS Convention does not specifically cover the sound signals for mobile offshore drilling units; C) The Coast Pilot is a navigational reference, but does not contain the regulatory requirements for sound signals; and D) The MMS (Minerals Management Service) Rules are specific to the offshore oil and gas industry, but do not supersede the international COLREGS requirements.
