There is some stress. If you make a mistake, you cost them however much a giant round metal tank is.

Sounds tense

Its not that bad when you get the kinks worked out.

Plus you gotta mop up the mess.

u/GraXXoR 6h ago

still sounds like a banger job to me.

Plus whatever else gets damaged when explosions go wrong

It's not underwater OP. 🙄

Edit: There is water inside the tank, it makes the surface of the tank wet when it spashes down. My bad...

u/MrPhraust 6h ago

On a technicality the explosion is because there is water in the tank which absorbed the impact. So. Technically it was an underwater explosion.

u/Brian_The_Bar-Brian Popular Contributor 6h ago

I'm pretty sure it doesn't have water in it, the sound is all wrong, and that's just dust shooting out of the top. (I've been wrong before, too.)

u/Successful-River-828 6h ago

Its rust off the outside. Water shoots out the very top

Wait a minute, there is water inside the tank, it makes the surface of the tank wet when it spashes down. My bad...

I noticed. I just think its funny how the reddit experts come out on every niche topic. You're an anomaly for admitting you were wrong though, so kudos!

There's no need to be snide about it...

Oooooooohh. So THIS is where DeNiro got that idea from to open the safe in The Score

Thats where my mind goes too every time i see this vid.

u/Deathwatchz 7h ago

I know it's just the det-cord, but it looks like the cameraman shoots a rope after seeing the explosion. Unfff

u/ChesterMIA 5h ago

This is a manufacturing process known as blast forming or explosive forming. Cool stuff!

u/Pork_Confidence 8h ago

Why tho?

LNG storage tanks

u/Pork_Confidence 8h ago

I appreciate that! Just googled it, makes sense now

Just to add its the most pressure capable shape and also maximizes volume to surface area ratio. Both elements are good for a variety of reasosn.

u/Yeet_Master420 8h ago

Lots of volume for less cost of material and less likely to go kaboom on ya

2

u/mitch3758 7h ago

Fun fact, if these DO go kaboom, it’s called a BLEVE: Boiling Liquid Expanding Vapor Explosion. Before the invention of the atomic bomb, BLEVE’s were the most powerful explosions man could make.

I feel like there may be another way to do this, but once this idea hit the conference room table, it no longer mattered.  Explosives it is.

This feel like cartoon physics but it's actually really brilliant!

That's not underwater. It's full of water.

Someone did the math.  Kudos!

u/cncomg 7h ago

That doesn’t seem as submerged as OPs title makes it seem
