It looks as if not only the bulkhead got separated but also the top-most ring where it was attached. I don't remember right now how that section looked, but maybe it was not the bulkhead at a fault but the seam between the first and second ring from the top.
- SECProto 7y agoI agree that's what it looks like. Interestingly, during fabrication, the bulkhead was attached to the ring, and then the whole ring was lifted up and welded on. Maybe there was interaction of the heat affected area from the two welds? The bulkhead was welded only ~100mm up from the bottom of the ring.
