Question 2280 Deck Safety
70% to passA tanker's mean draft is 32'-05". At this draft, the TPI is 178. The mean draft after loading 1200 tons will be _______________.
A
33'-00"
B
33'-04"
C
33'-08"
D
33'-11"
AI Explanation
The correct answer is A) 33'-00". The increase in draft due to loading 1200 tons can be calculated using the Tons Per Inch (TPI) value of the vessel. Since the TPI at the initial mean draft of 32'-05" is 178, the increase in draft from adding 1200 tons can be found by dividing 1200 by 178, which equals approximately 6.74 inches. Therefore, the new mean draft after loading 1200 tons will be 32'-05" + 6.74" = 33'-00". The other options are incorrect because they do not accurately reflect the increase in draft based on the given TPI value and the amount of cargo loaded.
