According to the NYTimes, OceanGate refused to undergo any sort of external audit/certification process [0]. I would imagine using an off the shelf, cheap controller would have been one of the first things to be flagged. Makes you wonder how many other critical components did they skimp on [0] https://www.nytimes.com/live/2023/06/20/us/titanic-missing-s...

I control+f'd for "refus" and didn't see a mention of this. To whom did they refuse? To whom do they owe a certification?

I don’t know in this case, but it’s often an insurance company.

Earlier quoted context omitted.

"Surfacing" unassisted would mean floating with the top of the submarine at water level. You still won't be able to open the door.

That's possible. Then at least some form of ventilation usable after surfacing should have been included if you're locking people in.

There is 96 hours of oxygen onboard, and even without any supplement, 5 people would survive in a space that large for at least half a day with no fresh air

The founder/CEO has said that he hasn't been on a single trip where everything went to plan...

I think the founder/CEO should be on a trip to prison for the negligence and mind bogglingly poor decision making surrounding this debacle.

He was on the sub.

He's one of the people on the lost submarine

With all the talk about failure modes of carbon fiber, the scariest part of this article is the photo of the display and light held up by screws drilled into the side of the pressure vessel.

Imagine someone falling onto that monitor at 4000 meters. When the operator accidently moves because of the joystick. If it wouldnt be so sad, it could be funny actually.

Are they required to carry insurance?

The US Navy uses an Xbox 360 controller in active service [0] Mass market has a lot of R&D to leverage so it makes sense. Nothing to say this is the cause of the fault and probably going to be more reliable than something hand rolled. [0] https://www.theverge.com/2017/9/19/16333376/us-navy-military...

Yeah, I'm not convinced this is in any way related to the issues. I'm far more concerned with the system that such a controller was plugged into than the controller itself. Commercial off the shelf pc? What kind of redundancy? How was power and power backup managed?

The guidance and control system seems to run on a GTK (?) app running on what looks like Ubuntu 10.04. An HDMI cable can be seen running to the monitor.

If I had to take a random guess, this system is probably some form of an embedded Atom/Geode type device (if not just a notebook PC) with some CAN or RS485/422/232 interfaces attached via USB.

From what I read it is also the first carbon fiber deep water vessel. I find that scary as carbon fiber does not start to bend before falure, it fails catastrophically.

I would honestly choose that over sitting on the bottom for 96 hours. Something about sitting there for 4 days with no hope is more terrifying to me.

You can donate a day to the remaining 4 people then.
