Question 4472Deck General70% to pass
The DEEP DRILLER is loaded as shown in the Sample Load Form #1 (Transit). If weather conditions make it necessary to ballast down to survival, how much ballast would be required?
AI Explanation
The correct answer is B) 4,086.5 long tons.
To ballast down to survival conditions, the vessel needs to have enough ballast to ensure the proper stability and freeboard for safe operation in severe weather. The sample load form provides the necessary information to calculate the required ballast. By subtracting the transit load (11,913.5 long tons) from the survival load (16,000 long tons), we can determine that 4,086.5 long tons of ballast are needed to reach the survival condition.
The other options are incorrect because they do not accurately reflect the difference between the transit and survival loads based on the information provided in the sample load form.
