alright. in my tepidly professional opinion* here are the actual major red flags with the titanic submersible
first, stuff that people are clowning on that isn’t actually a red flag at all
using starlink satcoms for their overall [surface] communications
i know it’s fun to clown on elon musk but starlinks are like. Fine. they work fine as satcoms. this is not the issue. none of these problems would have been solved if they’d been using KVH or somebody else instead
also these have fuck all to do with the tiny sub, since radio waves physically do not penetrate water enough to be useful for communications lol
the stupid game controller to steer
it’s actually super common to use COTS (commercial off the shelf) parts like that instead of some bespoke steering system.
they’re easily replaceable if they break, they’re designed to be integrated into larger systems, and you don’t have to do a huge amount of design work before you can even steer your thing
that being said. here is the fucked up design stuff that i notice
Where The Fuck Are The Chairs
if you don’t have seats inside your vessel, you don’t actually have a way of securing passengers during rough movement. i suspect that this makes it very dangerous or difficult to ascend quickly in an emergency.
i presume that they mean “messages in the form of text, sent via an acoustic signal”, not “they are literally using cell phones to text each other” because obvs cell phones (and most radio) would not work
it’s actually extremely unclear to me what system the sub and the mothership are using to communicate. idk if this is a “technology reporting hard” issue or if these people are being deliberately cagey. anyway they’re probably using some form of underwater acoustic communications, but what specific form it takes idk
regardless, the fact that they’ve had problems with this system in the past is a red flag
and the fact that their sub has apparently no internal navigation system is also a red flag. “not having GPS” isn’t really, since GPS doesn’t really work underwater (you need radio 😔), but they should have some kind of internal navigation– at the very least “here is my speed and heading and based on that my expected position is here on a map”
in a power failure situation, they would have been SOL
while it is “normal” for structures that are exposed to regular massive changes in pressure to have fatigue (imagine bending a piece of metal in and out over and over, eventually it will break– you want to catch and replace that before it happens), it’s weird to me that
the vessel’s depth rating was downgraded
without any public statement about what repairs were done, it nevertheless went back to the 4000ft depth less than a year later (in 2021)
they obviously have no “black box” system or any way to locate a missing vessel
most boats are required to have this! because most boats are required to be registered with and inspected by various authorities!
these guys deliberately skirted that rule by launching off a boat rather than from a port and therefore avoiding the need to get registered or inspected. lmao!
not that it likely would have helped to save these people if they had been alerted earlier, but it shows a desire to cover up mistakes
and like. obviously. you should get your shit inspected. nobody taking paying passengers anywhere should be allowed to be their own safety inspection authority.
the original sinking of the titanic was what led to SOLAS (safety of life at sea) rules being instituted. they’ve been updated several times since then, but they don’t yet cover submersibles like this, since they are relatively new. it’s likely that this incident will cause a new interest in updating the rules. as they say: every regulation is written in blood
*i’m a mechanical engineer who works in the maritime industry, but not like, a particularly related section of the industry– i do shit with cargo containers mainly. no further info on my credentials will be given since i have no desire to doxx myself on tumblr dot edu. i’ve tried not to say anything too wrong or out of my depth in this post but my opinion is “guy with an engineering degree who reads news articles” level of informed. so take your maximum grains of salt
