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.
When a vessel, such as the COASTAL DRILLER, expects to encounter high winds (75 knots in this case), the tip-of-can (TOC) position should be positioned at a sufficient height to ensure the stability and leg strength requirements are met. Based on the stability and leg strength regulations for offshore drilling rigs, the TOC position should be at 60.50 feet to maintain the necessary stability and leg strength to withstand the expected high winds.
The other options are incorrect because:
A) 0.00 feet (flush with bottom of hull) would not provide the necessary leg strength and stability.
B) 1.20 feet and C) 12.38 feet are too low to meet the stability and leg strength requirements for the expected 75-knot winds.
