Oceangate Submarine Disaster - What REALLY Happened

We've all been glued to our TV sets hoping and praying that the 5 souls aboard the Oceangate Titan would come home safely, after being lost at sea. But sadly, as the wreckage was found, we know that is not the case. This is a sad tragedy, but so much about this story deserves a deeper look. As an engineer, I'm furious with some of the things that led up to this event, so today let's break down what really happened and figure this out together.

For Lockridge, the engineer, this has got to be the worst feeling. He was right, he tried to stop it and was fired and sued for his well founded concerns.

[Zurvan]

The fact that it didn't have a surface radio beacon or bottom sonar beacon is astounding. The CEO really did cut corners that cost him and his customers lives. What other corners did he cut? What possessed him to use carbon fibre for the main hull?

Old retired Engineer here, mostly worked in Aerospace. I think you covered this very well. I would like to touch on 2 points if I may.
First off is redundancy. When we build experimental aircraft, we try to figure in back up systems. You touched on this with the inability to navigate, locate, and exit the craft. Unlike most airliners flying today that have a whole backup system for comm, hydraulics, navigation, even the artificial horizon, this craft had little to no backup systems, from what I have seen.
Second is the fact that Engineers get constantly surprised even on the simple things. I recall that the Galaxy C-5 Starlifter was found to have the main supports turned to powder on the inside, showing no signs of stress on the outside. The only way to determinate this was through a destructive test.
While Carbon Fiber is a remarkable material, it is not a "one size fits all" material.
The people probably never knew what hit them. From what I was told, the implosion took 2 nanoseconds, and it takes 4 nanoseconds for your brain to register pain from your nerves.
Thank you your thought out presentation, I think you covered it very well. Also for letting me put my 2 cents in.
Smiles.

I've watched about 30 videos on this subject.
This is the most concise, informative of them all.
Excellent presentation.

I’m a retired nuclear submarine mechanic of 33yrs. Every thing that I touched to repair I and a QA inspector had to sign our name and badge number and the date for every nut and bolt that was to be torqued. Like I told my apprentice, “I want you speak out if you think something is wrong because, “if you fail, I fail, if I fail you fail and that is not an option, the boat depends on us”!

Great video. I’m a Mechanical Engineer with 40 years of experience and am appalled at what the owner of OceanGate did with this project and the lack of following basic engineering protocols and procedures to verify the safety of the vessel for multiple dives with passengers. If the owner wanted to risk his life fine. But I’m sure the Father did not understand the risk he was undertaking with his son. The saying “You don’t know what you don’t know” is so true. What the owner did is criminal in my opinion.

[suemccord]

NDT inspector here. Great explanation. I'm absolutely floored no stress testing was done after every use.

[tonyelkan]

The hull was made of two different materials, carbon fiber and titanium. I would assume that those materials deform differently under such extreme pressure. Wouldn't that create a huge additional risk of failure at the joint between them?

Nice video Ricky! I'm an electrical engineer with about 45 years of experience, and the attitude Stockton (may he rest in peace) articulated, that at some point, safety becomes pure waste horrified me. We should NEVER put human safety on a back burner like that. Yes, there are always risks in any endeavor, but the risks must be managed, not ignored.

It's a cemetery not a circus attraction. I'm sorry for the lost and their loved ones but it shouldn't be a tourist attraction.

Passengers said they could hear cracking when they were in the sub. One guy said he was allowed to drive it and could tell when he was going deeper because the cracking sounds would increase. When you hear cracking, you're hearing the fibers of the carbon fiber breaking OR you're hearing the resin that holds the fibers together breaking or both. When you hear cracking, your carbon fiber part is now weaker, even if you can't tell there is anything wrong with it by looking at it.

[tinacatharinaeden]

Wow! This video explained in more detail and was easier to understand than most videos and comments on this unfortunate disaster. Well done! Thank you so much.

[SleepNeed]

The more I hear, the more shocked I am that it survived as many dives as it did before this happened. As the phrase goes, "Regulations are written in blood." So many corners cut, so many lessons from the past ignored, and so much ego on Rush. 

Sadly, this ended in a predictable fashion and it cost the lives of five people. At least I take some solace in knowing that they all died instantly and without pain.

[toolittletoolate]

How is this twice as long as the CBS post yet a million times more informative? Fantastic work. Crazy to live in this new age where niche youtubers do a better job at reporting on events then the news.

[LXSeaV]

I’m not an engineer but I think conscientious engineers just got a lot more respect and appreciation!

[stitchlilo]

Great presentation! Thank you for that thorough explanation as to what happened. At the end of the day, five lives were lost and no amount of money in the world will bring them back.

I just feel extremely bad for the young man that perished in this disaster. He didn't even want to go but he wanted to bond with his father so much he threw out his fears and went anyway. That bothers me a lot.

[Elric]

James Cameron himself voiced concerns about the composite hull on repeated dives. He didn't say anything before the accident because he assumed an engineer would flag the weakness. And an engineer DID flag the weakness. They fired him. A tragedy.

[corylyonsmusic]

Not enough people are talking about Mr lockridge. Good on him for doing his job like he's supposed to and caring about the safety of the product.
