 found more pics. the O rings weren't properly designed, the one on the left sits too deep because the groove wasn't machined correctly. There's also a plunge hole (presumably to get the undercutting tool in) that is a serious weak point. the end sections of the hull, after being machined down to length, left these pieces behind, which show evidence of delamination. on the right, they put a bright light behind it and you can see it all the way through. very bad! the flooring material (they used HDPE, high density polyethylene) was definitely not flameproof. what if some of that messy wiring shorted out and set fire to the floor? just everything about this vehicle was shoddy.  @tubetime I’ve seen disposable drug smuggling boats wash up on the coast that are more resilient than this.  @tubetime am thisclose to a panic attack (no, am not joking) reading this. this was a death sentence from the very beginning. when Walter Benjamin said that capitalism is a death cult, this is exactly what he meant. @tubetime "Fake it 'til you make it"-mentality when it comes to extreme conditions.  @tubetime summary of the report: this is what happens when you let billionaires/techbros design and/or build stuff that should keep lives secure and safe.  @tubetime Sheesh, this feels more like a movie prop than something intended to go to extreme ocean depths. We've all done hacky things but not in such unforgivable environments with risk of life for....tourism. @tubetime You are doing an important service by posting all this information. Thank you!   @tubetime They were probably thinking when has a failed O-ring ever been the weak point that led to the catastrophic failure of a hugely expensive vehicle while carrying a civilian to an extreme environment where only a tiny few humans can afford to visit? @tubetime this "conical" groove means the o-ring will expand in it under pressure and prevent it from being watertight enough, or is it just me? Not only this requires a tool entry hole that adds a point of failure, but a simpler straight groove might have been much better for watertightness, right? Who designed that? Looks like they didnt even do basic homework on this. @f4grx no this is the standard way to capture an O-ring. a square groove would allow it to fall out. the trick is to use the right parameters so it compresses the correct amount. and i'm pretty sure there's a clever trick to eke the tool into place without leaving a plunge hole.  @tubetime alright, time to load up the next billionaire and keep it going, no time to waste, chop chop ⌚  @tubetime this is actually the most wild bit to me so far. Like the other stuff is mostly just being scrappy to an inappropriate degree and doing the same sort of stuff we'd do in robotics club but with lives on the line. But the fact that someone had to sit there and manually type in all of the numbers... that's not even scrappy that's just absolutely bizrarre. I always thought there was something funny how they had zero info on what happened to the ship... makes sense now.  @tubetime The more I read, the more horrified I am about how slipshod this venture was. |
