NTSB Titan Sub Report: Carbon Fiber Hull Defects, More

Jeff Ostroff reviews photos and preliminary testing released by the NTSB of the doomed OceanGate Titan submersible wreckage sitting on the ocean floor just 330 yards from the bow of the RMS Titanic, which sank in 1912. Testing reveals defects during the carbon fiber hull manufacturing, and the RMS's potential failure (real-time hull monitoring system) to indicate a hull failure was imminent. The wreckage of the OceanGate Titan sub was recorded as rescuers salvaged the debris from the bottom of the ocean floor with the Pelagius Research ROV known as Odysseus 6000. The ROV Odysseus 6K is an easily transportable, competent, and deep-sea system that integrates into ships. The ROV supports executing time-critical search, rescue, and recovery operations.

This video shows the Ocean Gate Titan submersible from a titanium hemisphere nose cone and a piece of carbon fiber in the foreground.

I'm retired from 45yrs in aviation. While working at Textron Aviation, I was composite certified for carbon fiber and Kevlar repairs. When working carbon fiber, you never sand thru layers of fiber. If you do, you just compromised the structural strength of the carbon fiber. Just the fact they were sanding out wrinkles in the layers means that whole area was compromised. The peelply is woven teflon fabric used for keeping bagging material from sticking to the epoxy matrix during curing. after cure, the peel ply is just peeled off and discarded.

Aerospace NDT Inspector here: this is horrifying on a whole other level. Delamination, porosity, cracks, I look for these things down to .030" and reject them due to the fact that they'll eventually grow to threaten the structural integrity of the vehicle. To think that something this riddled with defects was sent down nearly 2.5 miles underwater... absolute death trap.

Thank you so much for the great analysis!

[devzeppelin]

If Rush hadn't died in the implosion he'd be royally fucked right now.

[thomasm.]

Thanks for all the details and the calm analysis... I am not an expert on submarines, but I was a welder in the German military for mobile bridges and anything that was sunk in water. All our work was checked with ultrasound. Sorry, I would never trust my life to any technology that I couldn't check down to the smallest detail.

Maybe the loud noise on dive 80 was the 5 inch thick hull becoming 5 one inch thick hulls when the layer adhesive failed in a hoop

[krags.allander]

This is the best video of the aftermath of the Titan I've seen. Very well done.

[ryanrohauer]

the idea that they were sanding down inperfections is BONKERS to me thats obviously going to weaking the carbonfiber wraps... INSANE

[s.porter]

Retired submariner, this thing was an accident waiting to happen..see thresher...many corners cut, and no inspection and recertification, I'm an so not surprised! One the company that built it, two, many submersible professionals advised not to construct like this

[DeeEditor]

The acoustic sensor data was very interesting to see epsecially when they layered all of them over each other. Sensor data should have been checked and compared after every dive with the previous one. Maybe it was checked and briefed by the analyst team, and Stockton simply brushed it aside.

[flapjack]

@10:25. That's not a crack. Note the five bolt ends protruding from it. I think it's the twisted remains of the steel frame that the outer skin attached to.

[Mikahaan]

Jeff, those green things are the green oxygen bottles that were on-board to supply oxygen to the internal atmosphere ... they are totally crushed and folded from the energy of the implosion. Solid steel O2 bottles!

[beeble]

26:05 Not sure exactly what that guy's doing with his cloth, but he's getting his greasy fingers on one part of the titanium ring while he's wiping another part. Is that the side that gets the glue?

[mercoid]

It was a toilet paper core wrapped in duct tape with two halves of a plastic Easter egg glued to either end. And people paid 1/4 million a head for the privilege get in it. Stupid.

[manofaction]

Anyone who walks into an established close-knit community like divers and submariners, and throws money around like a drunken sailor just to try to come in and "Rewrite the rules", needs to be avoided and exposed at all costs.

These people are guilty of negligent homicide. The arrogance, lack of safety, and lack of their own amature self awareness exhibited by all involved is just staggering.

For all involved, Carbon Fiber is not used to make submersibles, no matter how much you wish it to be so. parts, maybe, depending on the part, but not for deep dive subs.

This is just tragically comical at how willfully arrogant in their ignorance this whole organization was in this endeavor.

I've watched more than a few videos on Oceangate, and yours is the best of all of them as far as explaining complicated topics to the general public. The graphics help a lot, too. Thank you!

[JK-trmt]

The message is clear. The titanium domes survived. The carbon fibre delaminated under the immense pressures. At those depths and huge pressures use titanium or some strong metal, not carbon fibre! All those previous noises on previous dives suggest that toilet roll was continually delaminating. Did Stockton ignore what the sensors was telling him all along?

[arturobandini]

I have no prior interest in this subject (deep sea exploration) but this shocking case really feeds my layperson's and morbid curiosity.

[wtkgkpv]

I was a Oil Industry NDT Inspector I did UT and PMI (Ultrasound and Positive Material Identification). When I saw the defects and visual voids. My mouth just dropped. How did this make it out of the factory. Just the visual inspection alone is enough. I wouldn't want to be the Inspector that passed that carbine fiber to be used for what it was used for. After the BP accident we were warned heavily to double check our work before we sign off on anything. Because just like this accident people's lives are on the line with this stuff and criminal charges can be filed for negligence.

[soulure]

If Cockton Mush had somehow survived, I feel I can hear his dumb voice in my head during this video saying, "look at all these reusable parts!"
