The marine riser on the DEEP DRILLER should be disconnected if it appears the mooring line tensions will exceed 522 kips or the ball joint angle will exceed _______________.

A 4°
B 5°
C 7°
D 10°
AI Explanation

The correct answer is D) 10°. The marine riser on the DEEP DRILLER should be disconnected if the ball joint angle exceeds 10°. This is because exceeding the 10° ball joint angle limit can compromise the structural integrity of the riser and lead to potential damage or failure, which could be hazardous during offshore operations. The other answer choices (4°, 5°, and 7°) are incorrect as they do not represent the actual limit specified for the DEEP DRILLER's ball joint angle.
