Question 3542 Deck General

The correct answer is B) to prevent chafing at the lower end of the pendant. The design of a spring buoy helps to prevent chafing at the lower end of the pendant, which is the rope or cable that connects the buoy to the anchor. The spring in the buoy allows it to move up and down with the waves, reducing the wear and tear on the pendant and preventing it from becoming damaged or worn down over time. The other answer choices are incorrect because they do not accurately describe the primary purpose of a spring buoy's design. Option A is incorrect because a spring buoy is not used to mark the approach to a rig's location. Option C is incorrect because a spring buoy is not used to help an anchor handling vessel back toward a rig. Option D is incorrect because a spring buoy is not used to retrieve the anchor itself.
