Question 3749 Deck General

70% to pass

The helicopter deck of a MODU must be marked with the units identification, appropriate aiming circles, and a continuous line on the perimeter which is _______________.

A 8 inches wide
B 16 inches wide
C 24 inches wide
D 32 inches wide
AI Explanation

The correct answer is B) 16 inches wide. The Coast Guard regulations state that the continuous line on the perimeter of the helicopter deck of a MODU (Mobile Offshore Drilling Unit) must be 16 inches wide. This requirement is specified in the Code of Federal Regulations (CFR) under 46 CFR 109.433(c), which outlines the marking and lighting requirements for helicopter decks on MODUs. The other options, 8 inches (A), 24 inches (C), and 32 inches (D), are incorrect as they do not match the regulatory requirement of a 16-inch wide continuous line on the perimeter of the helicopter deck.
