When extracting the legs from the soil, the hull of the COASTAL DRILLER may be pulled down until the draft is _______________.

A one foot deeper than calculated afloat draft

B one foot less than maximum load line draft

C at the maximum load line draft

D one foot deeper than maximum load line draft

AI Explanation

The correct answer is A) one foot deeper than calculated afloat draft. When extracting the legs of a jack-up rig like the COASTAL DRILLER from the seabed, the hull may be pulled down until the draft is one foot deeper than the calculated afloat draft. This is to ensure the hull's stability and prevent the rig from becoming unstable or overturning during the leg extraction process. The other options are incorrect because they do not accurately reflect the expected draft increase during this operation.
