The implosion of the “Titan” is not only a tragedy, but also a lesson in what can happen when technology is recklessly and excessively sparingly used. If you take a look at the submersible and the films from its time in service, you will discover a few things that seem strange.
First, the unit was entered by opening the front pressure hull. There was no roof hatch. Now this is the first time I have seen a submersible without a roof hatch. So how should one be able to leave the “Titan” at the surface after an accident? The answer is: never.
Then the cables to the side drives and underneath the hull were not really fixed, but flapped around loosely. This not only looked disorderly, but could also become a hazard.
I think the combination of a CFRP cylinder with two titanium domes is worth discussing. But CFRP by itself is a problem and has never been used at about 390 bar external pressure on a manned submersible. To that end, it was used for a cylindrical component, not a spherical one. The question arises as to what the temperature variations during the dives and the stress during the considerable pressure change did to the material.
Also, the press release states that the one glass panel on the front was only rated to 1,300 meters. In addition, it was much larger than on other submersibles operating at that depth. Did it ultimately burst?
The technical interior may seem strange, but certainly worked insofar as the software developed for it allowed. Whether the controller was from Logitech or Lockheed is irrelevant. The one from the department store has already been tested by many thousands of users. I would also not buy the interior lighting where it is expensive, but where it is available at reasonable prices in the long term. Expensive does not always automatically mean good. This is a typical misconception of the well-to-do affluent bourgeoisie.
But it is reprehensible to throw compliance with safety requirements wet blanket overboard while being responsible for the well-being of your passengers. So far, this has always been bitterly avenged – aviation history is full of such incidents. The burgeoning industry of tourist expeditions to the deep sea could be set back considerably with this accident – which is perhaps a good thing. Not everything needs to be developed for tourism. After all, the “Titanic” is also a great burial site that should be treated with the appropriate reverence
