The Titanic director has made 33 dives to the shipwreck and visited ocean depths in a submersible he built himself. He compares OceanGate to the Titanic in that both ignored safety warnings.
Pressure hulls should be made out of contiguous material like steel, titanium, ceramic or acrylic, he explained, in order to do modeling and finite element analysis to "understand the number of cycles that it can take." That's not the case with a composite material, like carbon fiber, made of two different materials blended together.
"And so we all knew that the danger was delamination and progressive failure over time with microscopic water ingress and ... what they call cycling fatigue," he added. "And we knew if the sub passed its pressure test it wasn't gonna fail on its first dive ... but it's going to fail over time, which is insidious. You don't get that with steel or titanium."
Apparently he built the sub he used to go to the titanic and into the Mariana trench. Dude must be intimately familiar with this sort of thing with that experience.
Like, I don't trust carbon fiber for my bicycle frame and stick to steel because that shit cracks easily. I can't believe this guy rolled the dice with carbon fiber on a fucking deep-sea submarine.
The real red flags here were the carbon fiber hull and the fact that the Titan wasn't even certified or properly tested to ensure it could survive the stress of repeated dives to such extreme depths.
It's kinda insane that OceanGate got away with taking paying tourists down in that thing for as long as they did.
Cmdr. Reed Koepp told USA Today at the time the controllers were cost-effective and came with an added bonus — young sailors already knew how to handle them.
At least two major weapons systems that the US military is focusing on utilize Xbox-style controllers, Task and Purpose reported in March.
Girguis said making fun of the gaming controller in the submersible was appealing because it's "an easy target" but that a lot of undersea vessels "use similar controllers."
It's a question of quality control. Military grade equipment is not the same as consumer grade equipment. That's why we have grade in the first place.
