Question 4271Deck General70% to pass
The DEEP DRILLER is loaded as shown in the Sample Load Form #1 (Transit). What are the new LM (longitudinal moments) if the entire contents of Salt Water Ballast Tanks 1P and 1S are discharged?
AI Explanation
The correct answer is A) 5,191 ft-tons.
Discharging the entire contents of Salt Water Ballast Tanks 1P and 1S would reduce the longitudinal moments (LM) by the amount of weight removed from those tanks. Based on the information provided in the Sample Load Form #1 (Transit), the LM for those two tanks is 5,191 ft-tons. Therefore, the new LM after discharging the ballast would be reduced by 5,191 ft-tons.
The other answer choices are incorrect because they do not accurately reflect the change in LM resulting from discharging the ballast tanks. Options B, C, and D do not correspond to the correct LM value based on the information given in the sample load form.
