DKTanker Posted June 21 Share Posted June 21 What I find interesting is that the craft was a free swimmer, I was under the impression that all crewed deep sea diving vessels were tethered. Link to comment Share on other sites More sharing options...
Stuart Galbraith Posted June 21 Share Posted June 21 Pretty sure Alvin, which Dr Ballard used to discover the Titanic, was a free swimmer. When you have 12000 feet of line, a tether would probably cause more problems than it solves, at least for manned vessels. Link to comment Share on other sites More sharing options...
Burncycle360 Posted June 21 Share Posted June 21 Do they have a second craft on standby for these sorts of things? Does the submersible emit an audible sound like a periodic chirp? Link to comment Share on other sites More sharing options...
Stuart Galbraith Posted June 21 Share Posted June 21 Nope. Reportedly they hung banging last night in 30 minute intervals for 4 hours, but thats about it. Link to comment Share on other sites More sharing options...
Josh Posted June 21 Share Posted June 21 Even if they find it, I can’t imagine there’s anyway to transfer personnel off it. They were all dead the moment they no showed. Link to comment Share on other sites More sharing options...
Stuart Galbraith Posted June 21 Share Posted June 21 There are apparently 7 different systems to get to the surface. The easiest is the sandbags which can be dropped leaving just positive boyancy. They had a similar problem on Alvin when they had an electrical failure. They jettisoned the concrete ballast, voila, bobbed to the surface. That this hasnt happened suggests major structural failure. For all we know the hammering might have been someone doing running repairs to a trawler.

EchoFiveMike Posted June 21 Share Posted June 21 Take all the decision makers at this shitshow business, wrap them up in cyclone fencing, attach a 500lb(ish) granite memorial stone and kick them out over the Titanic site. Liquidate all their assets to recover some of the public funds squandered on this shitshow. S/F....Ken M Link to comment Share on other sites More sharing options...

I'd place a little more confidence in these stories were it not for the fact that these tapping noises seem to be reported every time a sub sinks. The crew of the Kursk for example were also reportedly banging on the hull days after the accident, but we know now that that can not have been real. Unfortunately it is looking like it is a goner.

Stuart Galbraith Posted June 21 Share Posted June 21 Yeah, the report from the coasties sounded a lot more pessimistic about the banging sounds. For all we know it might be the sound of Titanic breaking up. Link to comment Share on other sites More sharing options...

shep854 Posted June 22 Author Share Posted June 22 Simply not being able to open the hatch from the inside would be a trip killer for me, no matter how safe the vessel seemed to be. Link to comment Share on other sites More sharing options...

Of all the criticisms of the vessel, IMO, that is one of the least concerns. The only time it would be safe to open that hatch is on or near the surface. Any deeper than that and the pressure of ingressing water would be overwhelming and that's if the pressure wasn't so great that pressure prevented the hatch from being opened.

Harold Jones Posted June 22 Share Posted June 22 I'm really surprised that there isn't some kind of locator beacon on the thing. It seems like a no brainer to have one. Link to comment Share on other sites More sharing options...

Any deeper than that and the pressure of ingressing water would be overwhelming and that's if the pressure wasn't so great that pressure prevented the hatch from being opened. A hatch on the topside would make more sense. Either way, if the pressure differential were beyond a few psi, noone could open a hatch outwards. A pressure equalizing valve would have to be added just for basic opening to handle modest barometric pressure differences. Remember, a psi difference across a large surface adds all of that square inch amount against the size of that hatch. So a 3 foot diameter hatch with a 5 psi outside difference would require 5000 lbs of force to open. 18”*3.14^2=1017x5psi This is why exploding truck tires are super dangerous when they let lose.

shep854 Posted June 22 Author Share Posted June 22 . Agreed about all the other potential flaws, but after realizing how the hatch was secured, I would have bailed right there. As Aaron pointed out, imagine bobbing on the surface and suffocating because the hatch. Apollo I was also horrifying... Link to comment Share on other sites More sharing options...
