In email messages seen by the BBC, Mr Rush had previously dismissed safety worries from one expert, saying he was "tired of industry players who try to use a safety argument to stop innovation".
Seems as though he thought he was fighting against the stifling of innovation. In reality it seems he truly was unsafe and definitely should have had better oversight.
The pressure is why I’m wondering what was survived. I mean, fire pistons are a thing- and that’s a far smaller pressure differential. They were probably flash-steamed before they ever knew what happened.
the forces involved in an implosion are significantly worse than the average person thinks. if they find anything that isn't raspberry jam I'll be very surprised.
Exactly this. The reality is his submersible was dangerously unsafe, it’s a bit of a misconception that it was a ticking time bomb because of fatigue- that is a thing related to metallic (crystalline )structures and stress cycles-as a composite, CF doesn’t have that.
What Cameron was getting at is that with titanium and steel, it’s can be modeled very easily- and because steel has a relatively high tolerance before fatiguenstarts… they literally can engineer around it and make parts that effectively don’t have fatigue (unlike aluminum, where every elastic bend degrades it’s structure.)
The problem with composites is that they are very difficult to model. You degrade the polymer (that is epoxy) and it weakens the hull. You drop the sub on the deck, get a delaminated bit. Whatever, once there’s damage to the structure it’s done for.
CF bikes for example, used in professional bike racing are retired after a crash because there’s no way to examine delaminating off the edge, which makes them extremely dangerous to ride,
The kind of people unwilling to have 3rd party certification to do much as validate your pressure hill is thick enough is unlikely to scrap an entire custom pressure hill because some idiot screwed the monitor into it. (Or dropped it. Or noticed that there was some delam around the hatch or whatever else.)
Yes I saw in another video that monitor stands were attached to the wall somehow. Screws straight into the carbon fiber doesn't sound ideal, although I think they had some sort of internal cage structure, so it probably wasn't that bad.
If I were building a submersible, I’d have an internal fairing to allow mounting things like that, yes.
But then I’d also have included seats, and used viewport domes rated for the pressure depth…. And have someone not me give the sub a certification- because I recognize that I’m human and sometimes make mistakes.
There isn't any regulation of commercial submersibles like there is for ground or air. Anywhere around the world. So the "de" of deregulation is not applicable.
Should there be regulation? Yeah absolutely, if submersibles are going to be a thing. But that's just called regulation.
i think they are trying to say this is a perfect example of where things will head if we continue with deregulating industry as republicans think we should. where your boss can say "fuck safety i wanna make more money and if a few people are killed or injured well thats the cost of doing business."
Bingo. I've been to lots of countries with far fewer safety regulations than the US, and can we please stop fetishizing the cheapening of human life and well-being for profit in the US? Please? We came out of that phase in our development for good reasons.
