Question 5079Deck General70% to pass
The COASTAL DRILLER, while in transit, expects the winds to increase to 75 knots. In order to meet the stability and leg strength requirements, the tip-of-can (TOC) position should be at _______________.
AI Explanation
The correct answer is D) 60.50 feet.
To meet the stability and leg strength requirements in anticipation of 75-knot winds, the tip-of-can (TOC) position should be at 60.50 feet. This allows the legs to provide sufficient structural support and ensures the vessel's stability is maintained in the predicted high wind conditions.
The other options are incorrect because:
A) 0.00 feet (flush with bottom of hull) would not provide the necessary leg strength or stability.
B) 1.20 feet is too low and would not meet the requirements.
C) 12.38 feet is also insufficient to withstand the expected 75-knot winds.
