Question 3480 Deck General

The correct answer is B) 222 kips. The mooring lines should be adjusted to 222 kips in the absence of environmental forces when the DEEP DRILLER is anchoring in 600 feet of water. This is because the weight of the mooring lines themselves creates a tension that must be accounted for, even without external factors like wind, waves, or currents. The 222 kips value represents the appropriate tension to counteract the weight of the mooring lines at that water depth. The other answer choices are incorrect because they do not accurately reflect the mooring line tension required for a 600-foot water depth in the absence of environmental forces.
