Question 4563 Deck General

You are correct, the answer is A) allowable load. The load chart of a MODU (Mobile Offshore Drilling Unit) crane is designed to provide the crane operator with the maximum allowable load that can be safely lifted based on the combination of load radius and boom length. This information is critical for the operator to determine the safe working limits of the crane and avoid overloading, which could lead to structural failure or instability. The other options are incorrect because they do not directly relate to the purpose of a MODU crane load chart. The minimum horsepower required (B) and hoist rope strength (C) are not typically included in a load chart, and the maximum counterweight required (D) is more relevant for the crane's design and setup, rather than the information needed by the operator during crane operations.
