70% to pass

The DEEP DRILLER is moored in 600 feet of water. The average line tension is 190 kips. What is the total vertical component of chain tension?

A 55.3 long tons
B 428.8 long tons
C 442.4 long tons
D 678.4 long tons
AI Explanation

The correct answer is C) 442.4 long tons. The total vertical component of chain tension can be calculated using the formula: Vertical component = Horizontal component / tan(Angle of chain from vertical). In this case, with 600 feet of water depth, the angle of the chain from vertical is approximately 53.13 degrees. With an average line tension of 190 kips, the vertical component can be calculated as 190 kips / tan(53.13 degrees), which equals 442.4 long tons. The other options are incorrect because they do not accurately reflect the vertical component of the chain tension given the provided information. Option A) 55.3 long tons is too low, option B) 428.8 long tons is slightly too low, and option D) 678.4 long tons is too high.
