Question 3574 Deck General

The correct answer is D) load radius. The load chart for a MODU (Mobile Offshore Drilling Unit) crane relates the allowable load to the combination of the boom length and the load radius. The load radius is the horizontal distance between the centerline of the crane's rotation and the load being lifted. This is a critical factor in determining the maximum safe working load, as the load capacity decreases as the load radius increases. The other options, such as cable strength, boom angle, or boom strength, are not the primary factors that the load chart considers.
