Question 4436 Deck General

The correct answer is A) 35 feet. When elevating the COASTAL DRILLER in 100 feet of water, the unit should be placed at an air gap of 35 feet. This is because the standard air gap requirement for offshore structures is typically 35 feet to provide sufficient clearance between the water surface and the underside of the structure. This air gap ensures safe operations and allows for wave action and potential changes in water levels without the structure coming into contact with the water. The other options are incorrect because they do not meet the standard 35-foot air gap requirement. A 32-foot, 30-foot, or 25-foot air gap would not provide the necessary clearance and could potentially result in the structure contacting the water, which could compromise safety and stability.
