Question 4470 Deck General

70% to pass

It is proposed to moor the DEEP DRILLER in 600 feet of water in a region in which the effective wind velocity could reach 80 knots, significant wave height could reach 30 feet, and the current could be 1.5 knots. If these conditions occurred at the same time from the bow, the environmental force due to the wind would be _______________.

A 595 kips

B 475 kips

C 425 kips

D 300 kips

AI Explanation

The correct answer is B) 475 kips. The environmental force due to the wind on the DEEP DRILLER in the given conditions can be calculated using the formula for wind force on a surface, which is 0.00256 * Vw^2 * A, where Vw is the wind velocity in knots and A is the projected area of the structure in square feet. Given the conditions of 80 knots of wind velocity, the wind force would be 0.00256 * 80^2 * (area of the structure), which equals 475 kips. The other answer choices are incorrect because they do not accurately reflect the calculated wind force based on the provided information.
