Deck General USCG Question #3504 (Set 112)

Where do fatigue failures of wire rope mooring lines usually occur?

Official USCG Answer & Rule Citation

Correct Answer: Option A — Near the socketed end fitting adjacent to the anchor

Constant flexing, high tension, and localized stress concentration near socketed end fittings adjacent to anchors cause wire rope fatigue failures to predominantly concentrate at these points.
