Question 4458 Deck General

The correct answer is C) 522 kips. The marine riser on the DEEP DRILLER should be disconnected if the ball joint angle exceeds 10 degrees or the mooring line tensions exceed 522 kips. This is in accordance with the regulations and guidelines for offshore drilling operations, which aim to maintain the structural integrity and safety of the drilling rig under varying environmental conditions. The other options are incorrect because 348 kips (option A) and 500 kips (option B) are lower than the 522 kips limit, while 600 kips (option D) is higher than the specified limit.
