The COASTAL DRILLER, elevated in 150 feet of water with 0 knots current, 10 foot waves, and wind speeds of 70 knots may continue drilling if the maximum leg reaction is less than __________.

Correct Answer: Option C — 6,080 kips

Mobile offshore drilling unit operating manuals limit environmental loads and maximum allowable leg reactions under specific wave and wind criteria. For the COASTAL DRILLER elevated in 150 feet of water, survival and operational limits restrict total combined forces, capping the safe leg reaction at 6,080 kips.
