Question 3404 Deck General

70% to pass

The DEEP DRILLER is moored in 700 feet of water. The tension on anchor line #3 is 200 kips. What is the vertical component of chain tension for that line?

A 59.1 long tons
B 60.9 long tons
C 89.3 long tons
D 487.2 long tons
AI Explanation

The correct answer is B) 60.9 long tons. To calculate the vertical component of chain tension, we can use the formula: Vertical Component = Tension / Cosine(Angle). In this case, the water depth is 700 feet, so the angle of the anchor line is approximately 45 degrees. The cosine of 45 degrees is 0.707. Dividing the given tension of 200 kips by 0.707 gives us the vertical component of 60.9 long tons. The other answer choices are incorrect because they do not correctly apply the formula to calculate the vertical component based on the given information.
