70% to pass

When transferring personnel with a MODU crane, the weight of the loaded personnel carrier must not exceed _______________.

A 1/2 of the breaking strength of the hoist rope times the parts of line used
B 1/3 of the breaking strength of the hoist rope times the parts of line used
C 1/3 of the static rated load at the lift radius
D 1/2 of the static rated load at the lift radius
AI Explanation

You are correct, the answer C is the correct response. According to the regulations, when transferring personnel with a MODU (Mobile Offshore Drilling Unit) crane, the weight of the loaded personnel carrier must not exceed 1/3 of the static rated load at the lift radius. This is to ensure a sufficient safety factor and prevent overloading of the crane, which could lead to dangerous situations. The other options are incorrect because they do not accurately reflect the regulatory requirement. Option A and B reference the breaking strength of the hoist rope, which is not the appropriate criteria for determining the maximum personnel carrier weight. Option D proposes a 1/2 limit, which is less conservative than the 1/3 requirement specified in the regulations.
