Raising the Kursk
imrdkl writes: "Theres a conglomeration of Euro companies, from Euro countries renowned for their sea-prowess, who are working together with the Russians to raise their stricken sub. This will be some happy news, when they get it finished. Hopefully before winter gets bad up there in the "circle". A pretty good article, with a nifty flash animation which gives some notion of the scope of this engineering feat is to be found at USA Today."
It's very encouraging to hear about some good news throughout this very unsettling time. The Kursk is certainly a tragedy to itself, and I'm glad to hear that the men who died on that submarine are not being forgotten, especially in something as terrible as the recent terror attacks. Perhaps is this acceptance from Russia of European help a side-effect of the world-unity we are starting to experience? Hopefully this is a trend we can look forward to.

"Russian officials want to raise the submarine to eliminate any potential threat to the area's rich fishing grounds from its twin nuclear reactors and try determine the cause of its sinking."
I don't think romatic views take precedence over glowing fish... but I could be wrong.
Probably control. The lift bag system is nice and cheap, but tough to control. Once the load starts lifting the gas in the bags expands. That produces more lift, it rises faster, the gas expands more etc. The bags can rupture or dump their gas and then the whole thing sinks again.Jacks and big barge is the way to go here.
