Dome collapse

[Ioannis Georgiou]

Hi!

So far as I know the dome (forward and aft) were oval.

 

[Lajos Berínyi]

It's wrong, I think.

The forward dome was oval, the aft was circle. The fore dome has 7 pillars, but the aft has 5. The width was same. It's from the Olympic's, beacaouse we have photos only about these.

 

[Ioannis Georgiou]

Sorry, yes the aft dome was circle. But it was not the same sizes. The forward oval was 19x26 and the aft circle was having a diameter of 18,6.

Thank you that helps alot because some of the blueprints i have found and looked at showed the forward one being a circle to but after looking at some pictures i noticed the chandelier was oval and circles and ovals don't mix

Hello!When did the dome collapse?

 

[Augusto Félix Solari]

I think it collapsed at 2.15 am. Hope it helps.

 

[Haowei Shi]

Ok.

So the Grand Staircase's dome imploded because of water pressure, but there were windows and doors leading to the Grand Staircase, if the dome was covered in water to implode, how come these windows and doors didn't break and flood the area before the dome could implode?

 

[Yourj Benig]

I'm just wondering what caused the dome be broken. Was it because of the rushing water or because of the 2nd funnel? I'm just really curious.

 

[Brad Rousse]

I would assume the crushing weight of the water against a skylight and a dome never designed for such pressure did both in before the funnel keeled over. Besides, the second funnel heeled over to one side as it collapsed; in order to damage the skylight, it would have to have come straight down.

Thank you for that fine forensic explanation.. as the Old Rose said to mr. Bodine in Titanic. THANKS FOR THE INFO.

You always hear about the Dome over the forward Grand Staircase imploding due to the pressure of the seawater above it, this confuses me because there were obviously windows and doors which lead to the Grand Staircase, wouldn't have to water flowed through these doors and windows and the Grand Staircase area will with water before the water could cover the dome?

 

[TimTurner]

It depends on the exact situation. It takes water time to flow, plus the dome windows would have been beneath the dome itself. Plus, there's more than 80 feet of ship under the staircase, which is basically a big well down into the ship, flowing into most decks all the way down to F deck. So there's plenty of space for that water to go before it starts pooling up under the dome.

There's a good chance that there was a lot of air under the dome when it got pulled under. The weight of the seawater above would have pushed the dome inward into this air pocket.

I see what your saying there, I was under the impression that the water inside the staircase rose up to meet the waterline. Does this mean that water from the boat deck doors and windows flowing down into the stairwell could have created a whirlpool affect and sucked passengers deep into the ship?

Such a dome was not designed to be submerged with the force of many tons of water against it. It might have held together for a while but eventually the water was always going to swamp it. What surprises me is that there are actually so many windows still intact, both on the exterior and interior of the ship.

Cheers,
Adam.
