The DEEP DRILLER, at a draft of 60 feet, has 3,765 ft-tons of transverse moments. How much ballast should be transferred between tanks 1P and 1S to level the unit in list?
AI Explanation
The correct answer is A) 25.1 long tons.
To level the DEEP DRILLER unit in list, the amount of ballast that needs to be transferred between tanks 1P and 1S can be calculated using the given transverse moment and the formula for calculating the amount of ballast required to correct a list. The formula is: Ballast (in long tons) = Transverse Moment / (Draft x Displacement). Plugging in the given values, the calculation is: 25.1 long tons = 3,765 ft-tons / (60 ft x Displacement).
The other options are incorrect because they do not accurately reflect the correct amount of ballast required to level the unit based on the provided information.
