Airbags for ships in trouble
« on: Apr 02, 2012, 10:12 PM »
I was just thinking about the Concordia recovery, and how they'll probably use airbags to refloat her.  Doing a bit of digging about, it seems that ultra strong airbags like this are well proven (http://www.blueoceantackle.com/ship_launching_air_bags.htm).

So.... with enough money and willingness... couldn't cruiseships be fitted with emergency airbags which could be activated if it became apparent that the ship was in danger of sinking?  Concordia, in the open seas, would have completely sunk with a couple of hundred lost lives.  With airbags, surely this could have at very least have been slowed down, or added enough stability for a while to deploy all the lifeboats?

I wonder what it would cost...

Interesting thought Rob - surely it has to be worth a feasability study at least?

Rob, very interesting thought.
But....If Concordia had been in open seas it wouldnt have needed the "bags" in the first place.
You would have to look into the weight of ship you were expecting the bags to float...ie 1, 2, 3, or 4 compartments flooded etc.....
Where would the bags be deployed? Blow off a panel in the ships side? Inside a flooded tank?
Space would definately be an issue along with space for gas bottles etc.
Do not forget...before they deploy airbags, as many holes as possible will have been sealed and water pumped out.
Nice thought but unworkable I think.

You would not want to be around when the airbag went off in the compartment you were occupying. Potentially it could kill as many as the ship sinking

What about external airbags then? Aircrafts emergency slides work exactly the same way, on a ship it would just need to be... much bigger. I don't know wheter it could make a sinking ship float, but it would surely slow down the event.
