  1. I thought the same thoughts! I was of the opinion that the transition between the titanium rings and the carbon fibre shell was the weak point due to the dissimilar physical properties of the rings and shell. Reading this article showed that the end s of the shell also provided ingress point for the sea water to initiate delamination of the carbon fibre lay-ups. What I find really inexcusable was the lack of investigation into the cracking sounds during previous dives. To me at least that would indicate carbon fibre failure which is a cumulative failure ultimately leading to catastrophic failure. Is there a record of the locations where this cracking sound originated in he vessel?

  2. Dude, congratulations on quitting your job!!!!! FUCK working for a living, busting your ass black and blue to make someone else rich. I wish you the best of health, mentally and physically, and SHITLOADS of money 'till the day you die. Peace and rock on!

  3. No! Engineering calculations show that the axial end loading due to water pressure on the bulk heads (end caps) equals 1/2 of the radial loading on the vessel. Lengthwise cracks in piping and vessels is a common mode of failure, due to radial loading. Transverse (guillotine) failure, on the other hand, is quite rare. The essential difference between internally and externally pressurized vessels is the mode of failure. With internally pressurized vessels some warning signs are apparent, such as excessive increase in diameter, or, perhaps local bulging. Externally pressurized vessels are subject to catastrophic failure termed buckling failure. This is similar to buckling failure in building columns. For vessels the author termed it snap buckling which, while a new expression to me, seems most appropriate. I used to say that air liners and nuclear power plants do not suffer fools gladly. Add submersibles to that category.
