Question 2268Deck Safety70% to pass
A vessel's mean draft is 29'-07". At this draft, the TPI is 152. The mean draft after loading 1360 tons will be _______________.
AI Explanation
The correct answer is C) 30'-04".
To arrive at this answer, we need to use the given information about the vessel's mean draft, TPI, and the amount of additional cargo loaded.
The formula to calculate the change in draft is: Change in draft = Additional weight / TPI
Given:
- Initial mean draft = 29'-07"
- TPI = 152
- Additional weight = 1360 tons
Plugging these values into the formula:
Change in draft = 1360 tons / 152 TPI = 8.95 inches
Adding this change in draft to the initial mean draft, we get the new mean draft of 30'-04", which is the correct answer.
The other options are incorrect because they do not accurately reflect the increase in draft based on the given information.
