How to Sink a $3B Dollar Submarine: Leave a Hatch Open

Unfair to single them out. Submarines sink regularly, often due to human error. Grounding, collisions, even arson. Periscope hatches left open, oxygen ports closed.

Ever drive off and leave your trunk lid open? Forget a kid at the mall? Not call your Mom on Mothers' Day? Then you understand how easy it is for human error to occur.

When it’s a nuclear submarine and cost nearly $3 billion, you aren’t allowed to make mistakes of this magnitude. It really is that simple.

If a $3 bi product relies on not allowing people to make mistakes then their owner isn't allowed to complain when it inevitably fails.

I suggest reviewing the history of lost submarines, for perspective.

I’ve read many of them.

I suspect we are coming at the same thing from different angles.

You can’t have a culture that tolerates accidents like this, so get some systems in place to prevent them. It’s not about one person or piece of equipment. Swiss cheese model etc.

You said something quite different sounding than here. Here you mention systems to prevent mistakes. Your original post said

    you aren’t allowed to make mistakes of this magnitude. It really is that simple.

That does not mention prevention systems and instead put the blame squarely on the person making the mistake. They "simply should not have made the mistake, duh!"

Someone has allowed some crap systems to exist by the time something like this happens.

You’re right that my initial post makes it sound like I blame one person, and I do. However it isn’t just the person who didn’t close the hatch. I blame the whole command structure and particularly those at the top of it.

For humans, sure. Because we're all human. Hyperbole about perfect people is, what? Flagrant fantasy?

Yes, people do make mistakes; often. Airline pilots have long checklists of things they have to do before taking off, and more checklists for dealing with problems that inevitably crop up.

A doctor named Atul Gawande wrote a book named The Checklist Manifesto https://www.amazon.com/Checklist-Manifesto-How-Things-Right/...

Early in his career he did some research that showed that a simple pre-surgery checklist could reduce serious complications by more than a third. https://www.pbs.org/newshour/health/dr-atul-gawande-surgical...

Sure, but that's why modern cars have sensors and warnings when you accidentally leave a door open or don't use the seatbelt.

If leaving a hatch open causes one year of repairs and it contains a nuclear reactor maybe some automated sensors or checklists would be quite sensible.

My car will not start in gear, nor will it start without a foot on the brake.

Understanding and preventing human error is a basic part of design. Especially for things that cost $3B.

Human error that can be easily predicted and fixed with tech is kind of a design issue though. Shouldn't those all have sensors on them to stop this? People use Google calendar to remember what day is Mother's day, submarines can do the same.

Really all human error that has happened before is predictable. My rule for myself is to assume any mistake I've ever made, or imagined making, is possible.

I guess mistakes are more common than we would like them to be

Reads like clickbait. The thing you want to read is below the unrelated Youtube video talking about Russia's military strength. :-|
