ABoiler mountings attached to boiler nozzles must be opened and removed for examination every 8 years.

BAll mountings shall be opened up and examined by a Coast Guard inspector at eight year intervals after the initial inspection.

CBoiler mountings attached directly to the boiler plating by screwed studs and nuts shall be removed and examined every 10 years.

DAll boiler mounting studs or bolts shall be removed for examination by a Coast Guard inspector every 4 years after initial inspection.

AI Explanation

The correct answer is C. According to 46 CFR Part 61, boiler mountings attached directly to the boiler plating by screwed studs and nuts shall be removed and examined every 10 years. This is the correct answer because the regulation in 46 CFR Part 61 specifically states the requirement for boiler mountings attached by screwed studs and nuts to be removed and examined every 10 years. The other answer choices do not accurately reflect the regulatory requirement. The other answer choices are incorrect because they either specify a different time frame (8 years or 4 years) or a different method of inspection (opening and removing all mountings) that is not consistent with the regulation.
