Oceangate Titan - analysis of an insultingly predictable failure

54 Views
Published on 23 Jun 2023 / In Film & Animation

A preview of a world where 'regulation does not stifle innovation'. I wanted to clear up some points that have been widely misreported whilst discussing how mechanical failures of subsea vessels have been avoided for decades until now. This video could have been hours long if I spoke about everything in length, so consider it a brief summary.

I speak in present tense during the video, but it was made public that the crew are deceased as the video was rendering. Despite the remarkable predictability of this failure, the families of the victims have my sympathy.

not to mention with metal that you need to use sound devices as well as x-ray type equipment to test it for any cracks or weaknesses or stress points...
carbon fiber can be used, but it HAS TO BE USED WITH OTHER MORE RIGID MATERIALS, the same as any container that is meant to be pressurized with oxygen to be used for breathing...
using carbon fiber and aluminum you can have a container that works as good as a strait up steel or stainless steal container.

there is NO WAY a sub that small can stay down for 90 plus minutes....
it would have 30-40 min. of oxygen maybe, MAYBE!!!!

Not sure at all about the design but an emergency oxygen supply and CO2 scrubbing ought to have come bog stock on it.

@Life_N_Times_of_Shane_T_Hanson: yes, but you can see from the design that there was NO room for any of the necessities a proper sub needs including emergency systems.

@sbseed: The tail cone could have been the section that houses all that... just saying.

To be honest I was expecting a more 'refined looking' finished product. This is more like an unfinalized prototype.

What inspired this final design?

I think what inspired it, was a celebration of pride month. Then God stepped in to correct the situation. ------ But that guy - as so many other people do, pointed out many things that I observed but didn't register and didn't think hard enough about - one of them being all the cables and shit floating around outside the hull, that CAN get entangled in the Titanic wreck AND if the force is high enough, it can pull the cable loose / out of it's hole - and well with a water pressure at say 9,000 PSI - at the depth - a hole say 6mm in diameter though the hull is going to fill that sub in an instant.....

yes, its based loosely on the old bell design pods....

https://en.wikipedia.org/wiki/....Trieste_(bathyscaphe ------- On 23 January 1960, she reached the ocean floor in the Challenger Deep (the deepest southern part of the Mariana Trench), carrying Jacques Piccard and Don Walsh.[9] This was the first time a vessel, crewed or uncrewed, had reached the deepest known point of the Earth's oceans. The onboard systems indicated a depth of 11,521 metres (37,799 ft) ------- https://upload.wikimedia.org/w....ikipedia/commons/3/3 ------- https://upload.wikimedia.org/w....ikipedia/commons/3/3 ------- https://upload.wikimedia.org/w....ikipedia/commons/d/d

@Life_N_Times_of_Shane_T_Hanson: Even James Cameron's Deepsea Challenger has a clean design. https://alchetron.com/cdn/deep....sea-challenger-671bd

@hqwebsite: And they were not celebrating Pride Month, every year either...
