Question 4471 Deck General
70% to passIt 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 beam, the total environmental force would be _______________.
The correct answer is A) 620 kips. The total environmental force acting on the DEEP DRILLER in the given conditions can be calculated using the formula for environmental forces on offshore structures, which takes into account the wind, waves, and current. Given the water depth of 600 feet, the significant wave height of 30 feet, the wind velocity of 80 knots, and the current of 1.5 knots, the total environmental force would be approximately 620 kips (thousand pounds of force). The other options are incorrect because they do not accurately reflect the total environmental force acting on the structure in the specified conditions. The calculation requires considering the combined effects of wind, waves, and current, which result in the 620 kips value.
