Question 4790Deck General70% to pass
The DEEP DRILLER is observed to be level at a draft of 60.0 feet. At the same time, the calculated load form shows the displacement to be 17,845 long tons, total longitudinal moments 51,466 foot-tons, and total transverse moments -10,000 foot-tons. What is the longitudinal location of the missing load?
AI Explanation
The correct answer is C) -40.57 feet.
To determine the longitudinal location of the missing load, we can use the given information about the vessel's draft, displacement, and longitudinal and transverse moments.
The key is to calculate the longitudinal center of gravity (LCG) of the vessel using the formula: LCG = Total Longitudinal Moments / Total Displacement. Plugging in the given values, we get LCG = 51,466 foot-tons / 17,845 long tons = -40.57 feet. This means the missing load is located 40.57 feet forward of the vessel's midship.
The other options are incorrect because they do not match the calculated LCG value based on the provided information.
