Question 3410 Deck General

The correct answer is C) 487.2 long tons. The total vertical component of chain tension is calculated based on the mooring depth and the average tension on the mooring lines. In this case, the DEEP DRILLER is moored in 700 feet of water, and the average tension on the mooring lines is 200 kips. To convert the tension to long tons, we divide the tension by 2,000 lbs/ton, which gives us 487.2 long tons. The other options are incorrect because they do not accurately reflect the calculation based on the given information. Option A) 60.9 long tons is too low, Option B) 472.8 long tons is also incorrect, and Option D) 714.4 long tons is too high.
