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 change in KGL if the legs are lowered to the recommended value?

Correct Answer: Option B — 13.65 feet

Rig move stability calculations account for vertical center of gravity shifts (KGL) when leg heights are adjusted for high-wind survival or transit modes, resulting in a predictable 13.65-foot vertical center of gravity modification for the COASTAL DRILLER.
