The COASTAL DRILLER is loaded as shown in the Sample Load Form #1 (Rig Move). While in field transit, the wind speeds are predicted to increase above 70 knots. What would be the new KGL if the legs are lowered to the recommended value?

Correct Answer: Option B — 37.00 feet

Lowering the jackup legs per severe weather operating guidelines lowers the combined center of gravity. For the COASTAL DRILLER, adjusting the tip-of-can depth modifies the vertical moment distribution, resulting in a new effective KGL of 37.00 feet.
