Question 3573 Deck General

The correct answer is A) allowable load. The load chart of a MODU (Mobile Offshore Drilling Unit) crane enables the operator to combine the load radius with the boom length to determine the allowable load that can be lifted safely. The load chart provides the maximum weight capacity based on the crane's configuration, including the boom length and load radius, to ensure the crane is not overloaded, which could lead to structural failure or instability. The other options are incorrect because they do not directly relate to the primary function of the load chart, which is to determine the allowable load. The load chart does not provide information about the minimum horsepower required (B), the hoist rope strength (C), or the maximum counterweight required (D).
