It’s probably a floating roof. In the petro they use this for several reasons. Less contact between the product and air reduces oxidation. There is also less gass formed above the product reducing odour. But funny enough, it is mainly used to reduce risk of explosion …
I think that part kinda makes sense. The lid is domed, which increases its strength. The seam where the lid meets the walls would tend to be the weakest point. I’m more surprised there was such a violent explosion in the first place, usually they just burn. Could be that tank was partially empty and the area beneath the lid was a highly combustible fuel/air mix. Drone hits the tank, vapour ignites, and pop.
Domes are great in one direction, because any given section has something below it. They’re a 3D arch, something whoch would fall apart immediately if turned upside down. The great part about big rounded edges is that they distribute pressure more evenly and reduce the amount of seams present unlike a welded cube, for example.
More likely is that, yes, the connection between the roof and the rest was the weaker point and also the dome was able to basically be a parachute so it coukd catch air instead of just being flung in some random direction.
Yup, I’m not sure about this lid specifically, but some slide up and down the tank, since water is denser than oil they don’t really care if rain water gets past the seal.
Same logic could apply to airplanes. “In the unlikely event of a water landing, your seat cushion will become a flotation device.” Oh that’s nice, then why doesn’t the plane become A BOAT!? - some standup comic.
All jokes aside, I’m seriously impressed that the roof structure maintained it’s integrity and didn’t just shred to pieces in the explosion

Sure is.
Heyoooo (☞ﾟヮﾟ)☞

An arch or dome made of stone would instantly fall apart if flipped upside down. A steel one will perform just as well, as steel is isotropic.
IIRC, the lid can move up and down depending on how much content there’s in the tank. Something something provides pressure if it’s a gas.

Yeah I can’t believe they just didn’t make the entire building like that.
