Question 4564 Deck General

The correct answer is D) load radius. On a MODU (Mobile Offshore Drilling Unit) crane, the load chart relates the allowable load to the combination of boom length and load radius. The load radius is the horizontal distance from the centerline of the crane's rotation to the load. This is a critical factor in determining the maximum safe working load, as the allowable load decreases as the load radius increases. The load chart provides this information to the crane operator to ensure the crane is not overloaded, which could lead to instability or structural failure. The other options are incorrect because they do not directly relate to the information presented in the load chart. Cable strength, boom angle, and boom strength are all important factors in crane operation, but they are not the primary variables shown on the load chart.
