Question 4565 Deck General

70% to pass

On a MODU crane, the boom indicator tells the operator what the boom angle is compared to the _______________.

A minimum radius angle
B horizontal position
C boom stop angle
D vertical position
AI Explanation

The correct answer is B) horizontal position. The boom indicator on a MODU (Mobile Offshore Drilling Unit) crane displays the boom angle relative to the horizontal position. This information is critical for the crane operator to know the position of the boom and calculate the load capacity and reach of the crane. The boom angle is not measured against the minimum radius angle, the boom stop angle, or the vertical position - it is specifically referenced to the horizontal plane. The other answer choices are incorrect because they do not accurately represent the reference point for the boom angle indicator on a MODU crane.
