So in my haste in trying to pack a lot info in a short area I didn’t really explain it well james Cameron was explaining that the company said they chose acoustic testing of the carbon fiber hull because, according to the company, hull scanning of carbon fiber hulls is as not doable due (I forget what exactly.) cameron contended that even if that was true, acoustic testing is not adequate because what you don’t want is the water penetration I described earlier, and his believe was the acoustic testing had too high of a failure/miss rate detecting it or adequately reporting it. But, he also spent some time, explaining that he didn’t think their clams about hull scanning was correct to begin with. Link to comment Share on other sites More sharing options...

Ultrasonic can be done and would be excellent for water intrusion. X-ray should do well also though it is a lot more finicky. Link to comment Share on other sites More sharing options...

I believe ultra sonic and x-ray were what “hull scans” referred to i believe acoustic testing, to the best of my knowledge, meant taking baseline acoustic measurements of how it handled whatever sound waves, and comparing it in the future to determine how much the hull has deviated from its baseline cameron’s explanation was that it has a high miss/failure rate. They’re looking for separation of the layers in the 6” of carbon fiber. That separation is caused by the water intrusion. Cameron’s criticism was along two main points: - unreliable to be sure about the level of water intrusion - unreliable because testing after dive number X means nothing about dive number X+Y with his tangential third main point being yours - he thought the excuse for not doing hull scans was bogus, like you and it was part of the letter authored by the community to the company stating they thought this was an unsafe way of doing things Cameron’s other main criticism was that fiber woven hull designs, which are not new as the company liked to sort of pretend but we’re rarely used and not viewed favorably in the community, have a fundamental flaw regarding aforementioned layer separation and testing because it violates a basic ethos of deep sea diving which is that hull integrity should never be an issue. You should not have a sub with a design that questions hull integrity, and you should not have a maintenance/inspection process that leaves rooms for questions about hull integrity. every time you go out you should have absolute confidence hull integrity will not be an issue. There’s enough other **** that can go wrong and be serious, hull integrity should not be on the bingo card but in this case design and practices violated this fundamental way of doing things Link to comment Share on other sites More sharing options...

Destino Posted June 24, 2023 Share Posted June 24, 2023 Listening to that James Cameron interview, he mentions what his concerns were when diving. He wasn’t concerned that his sub design would implode but was concerned with becoming entangled in a fishing net. That’s a fresh terror I’d never considered. 1 Link to comment Share on other sites More sharing options...

Simmsy Posted June 26, 2023 Share Posted June 26, 2023 Ok, I'm going to be that guy: what exactly happens during a catastrophic implosion? Are we talking a soda can getting crushed by a car situation? Are we talking someone balling up some aluminim foil type situation? Did the parts of the sub implode and the pressure from the water squeeze them from the inside out? What the **** happens? Whenever we get to that part, the reporter always says "we'll spare you the details". No! I'm coming to you FOR details, tell me what the **** happened.

Simmsy Posted June 26, 2023 Share Posted June 26, 2023 I've seen those videos, guys. I was looking for an answer to something similar to this video: I'm guessing that is something similar to a "catastrophic implosion", I'm just trying to get an idea of how the sub was crushed. Looks more like the "car running over a can" type scenario. Link to comment Share on other sites More sharing options...
The 12th Commandment Posted June 26, 2023 Share Posted June 26, 2023 Basically a car/soda can scenario where there are cars pressing from all directions simultaneously. Link to comment Share on other sites More sharing options...

Fergasun Posted June 26, 2023 Share Posted June 26, 2023 I know that people have been talking that implosion happened immediately and the passengers didn't know what was happening. It is possible they had some warning with cracking and other noises as it is being discussed (probably via channels James Cameron is plugged into) the Titan communicated they were coming up and had released their ballast. Additionally they had the useless hull integrity system.... which was practically useless. I still question -- and now I can articulate it better -- that if the deep submersible community had serious concerns, like James Cameron has relayed -- why were they not more vocally public. "We sent him a very strongly private letter" is different than "we went to media numerous times and pointed out it was dangerous." Especially since Mr. Rush was actively inviting media for free publicity (ie. CBS news report). I am sorry, but if the experts were as concerned, why not one article that says - "We are Submersible Experts and believe the Titan is Dangerous." "Here's why I would not pay $250k to tour Titanic". There are a couple of bloggers on the expeditions this year that did not go down. . Link to comment Share on other sites More sharing options...

Fergasun Posted June 28, 2023 Share Posted June 28, 2023 Bumping and adding one more piece of information - the letter. This was sent in 2018, raising the concern of lack of certification in maritime environments. I still will contend that not enough in industry were calling Oceangate / Stockton Rush out publicly -- ie. he did a number of positive media and no one from media reached out to industry and neither did industry speak up to say, "Before you go on this thing... this is an experimental vessell and does not meet industry certification levels. Many of us have concerns." Sure, perhaps the company may argue or threaten a lawsuit, but the truth is a defense. This could have saved the Pakistani fellow and his son (but I am also thinking about bloggers and news correspondents who made trips). Especially since Stockton Rush was like, "it's safer than SCUBA diving... come on in!" I think my attention has waned until we see news from the recovery effort and future report updates.
