Titan sub noise heard on board support ship. 2

[LittleInch]

Just watched a new documentary by the BBC and others like Discovery so if you're interested look out for it. Implosion: The titanic sub disaster.

Key new part for me is that they released video of the moment a loud "crump" was actually heard on board the support vessel apparently through the hull with Rushs wife Wendy doing the monitoring of the sub and her saying "what was that?". They then got a message from the sub which must have been somehow delayed saying dropped two weights which confused them. It is pretty chilling to listen to alright. That and the fact that they were thought not to be at the ocean floor implies they were getting some warnings.

This is a clip but there are others.

Not much we didn't already know, but they have noted dive 81 (out of 88) where there was a very large bang heard which they reckon was the point at which the hull was on its last legs after a major internal failure.

The Discovery documentary maker back in 2022 was very unimpressed with the whole thing and persuaded the company to can their documentary as he was convinced it would end in failure and didn't want to be seen to promote the operation.

Looks like it's on Discovery pretty soon. If you're interested, it's pretty good and not that big into the human interest side, but does have input from the wife of the man and his son that died which is quite moving.

Scientists explore how the Titan submersible implosion was more than just a tragic accident

even a partial set of the test prescribed by the ABS - just one of many certifying bodies, the tragic outcome probably could have been avoided.

Agree.

Cyclic testing is what it needed in my view. Cycle the pressure thousands of times and see what the cracks do. They’d actually already done that indirectly with the first hull; but turned a blind eye by the looks of things to all the horrible cracking that was occurring.

Ultimately yes, SR was responsible for the culture and safety but the employees turned a blind eye, enabling it as long as possible.

Not strictly true; they knew quite early on that any dissent was going to result in immediate dismissal. Their hope was that they would be able to sway Rush to a safer conclusion, but that was not going to happen. While the Netflix documentary is heavily biased by the former employees, the facts are that multiple top management personnel were canned when they dissented, and SR did not do much to protect the submersible, even to the point of leaving it in Canada, exposed to the elements in winter, because that was cheaper than doing the right thing.

Carbon fiber and titanium are not inherently affected by weather. The effect of moisture on the bonds to metals that passivate is a relative new and unknown subject. The article I quoted above is from 2017. Maybe it wasn't so much arrogance but ignorance.
