LNG carrier tail shaft fracture

Used as a scale comparator in Tom's exchange with Pelloux. Possibly an instance of the canonical "LNG carrier tail shaft fracture" or "SS Libra LNG vessel tail shaft failure" — flagged in editorial register for confirmation.

I once had a fracture in a 33-inch diameter propeller shaft on a liquid natural gas tanker. I was kind of teasing Professor Pelloux — Professor Pelloux is still alive, he's retired, his specialty was fatigue and fracture — I said I bet I've got a bigger fracture than you've seen, because a 33-inch diameter shaft fracturing is pretty good size. He said, I don't think so. I said, what do you have? He said he had an anvil base to a big forging press, and the fracture was like 10 feet by 20 feet. That's a big fracture. If you had to pull it in two at 50,000 pounds per square inch, there are a lot of square inches in 10 by 20 feet.
